Hello,
This series depends on v4 of "media: rkisp1: Misc bug fixes and cleanups" [1].
The ISP integrated in the i.MX8MP is nearly the same as the rkisp1, and
so we can reuse the rkisp1 driver for it.
This series does some cleanup and refactoring of the rkisp1 driver,
(patches 1/55 to 46/55), and then adds support for the i.MX8MP (patches
47/55 to 55/55).

Add a register dump file in debugfs for some of the buffer-related
registers in MI, for the base address, the size, and the offset. Also
dump the appropriate shadow registers.

That's a very specialized file. I wonder if we should call it just
"mi_mp" if it needs to be extended later with other memory interface
registers for the main path. Or maybe even just "mi", to cover the self
path too ? The latter may be a tad too generic. What do you think ?

If the v4l2_device_register() call fails, runtime PM is left enabled.
Fix it.

There's no need to read the ID register every time streaming is started.
Do it once, at probe time.

The rkisp1_match_data structure contains device model-specific
information. It it referenced from OF match data, but that's an
implementation detail. Rename it to rkisp1_info to reflect its main
purpose.

The rkisp1_match_data structure contains device model-specific
information. It it referenced from OF match data, but that's an
implementation detail. Rename it to rkisp1_info to reflect its main
purpose.

To make it possible to use the rkisp1_info after probe time (for
instance to make code conditional on the ISP version), save it in the
main rkisp1_device structure. To achieve this, also move the info
structure into the common header, and document it.
While at it, drop a NULL check in rkisp1_probe() for the match data as
it can't happen.

Because it can't happen. The probe() function is only called if the
platform device matches one of the of_device_id, so
of_device_get_match_data() can't return NULL.

Because it can't happen. The probe() function is only called if the
platform device matches one of the of_device_id, so
of_device_get_match_data() can't return NULL.

The ISP version is stored in the media_device hw_revision field and
access from there in the driver. Now that we store a pointer to the
match data in the rkisp1_device structure, access the ISP version from
there to make the code clearer and avoid depending on the media_device.

* [PATCH 09/55] media: rkisp1: Make rkisp1_isp_mbus_info common

The upcoming CSI receiver split from the ISP to a separate source file
will need to be able to access the list of formats supported by the
driver. Move it out of the ISP's header and into the common header, and
add helper functions for accessing it so that the format list doesn't
need to be stored in the header.

The upcoming CSI receiver split from the ISP to a separate source file
will need to be able to access the list of formats supported by the
driver. Move it out of the ISP's header and into the common header, and
add helper functions for accessing it so that the format list doesn't
need to be stored in the header.

You could write this as
for (i = 0; ; i++) {
const struct rkisp1_mbus_info *fmt =
rkisp1_mbus_info_get_by_index(i);
if (!fmt)
return -EINVAL;
and drop the rkisp1_mbus_info_length() function. Up to you. Either way,

You could write this as
for (i = 0; ; i++) {
const struct rkisp1_mbus_info *fmt =
rkisp1_mbus_info_get_by_index(i);
if (!fmt)
return -EINVAL;
and drop the rkisp1_mbus_info_length() function. Up to you. Either way,

I usually recommend dev_dbg() for conditions that are triggered directly
by userspace, to avoid giving unpriviledged applications an(other) easy
way to flood the kernel log.

Agreed, this is a sensible thing to do. I'm still wondering if this
information might be missing, when having a build without DYNAMIC_DEBUG.
Nevertheless I'm fine to start with this debug output at least.

Move the calls to the active sensor's .s_stream() operation to the ISP
subdev's .s_stream(). This groups all handling of the active sensor in
one place, preparing for a rework of that code.

The rkisp1 driver requires the sensor to implement the pixel rate
control. Trying to operate without it will cause an error when starting
streaming. Catch the issue earlier, at bound time.

* [PATCH 13/55] media: rkisp1: Create link from sensor to ISP at notifier bound time

Links from sensors to the ISP can be created as sensors are bound. Move
the link creation from rkisp1_create_links() to the bound notifier, and
clean up the rkisp1_create_links() function while at it.

From: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
Links from sensors to the ISP can be created as sensors are bound. Move
the link creation from rkisp1_create_links() to the bound notifier, and
clean up the rkisp1_create_links() function while at it.

* [PATCH 16/55] media: v4l2-async: Add notifier operation to destroy asd instances

Drivers typically extend the v4l2_async_subdev structure by embedding it
in a driver-specific structure, to store per-subdev custom data. The
v4l2_async_subdev instances are freed by the v4l2-async framework, which
makes this mechanism cumbersome to use safely when custom data needs
special treatment to be destroyed (such as freeing additional memory, or
releasing references to kernel objects).
To ease this, add a .destroy() operation to the
v4l2_async_notifier_operations structure. The operation is called right
before the v4l2_async_subdev is freed, giving drivers a chance to
destroy data if needed.

Drivers typically extend the v4l2_async_subdev structure by embedding it
in a driver-specific structure, to store per-subdev custom data. The
v4l2_async_subdev instances are freed by the v4l2-async framework, which
makes this mechanism cumbersome to use safely when custom data needs
special treatment to be destroyed (such as freeing additional memory, or
releasing references to kernel objects).
To ease this, add a .destroy() operation to the
v4l2_async_notifier_operations structure. The operation is called right
before the v4l2_async_subdev is freed, giving drivers a chance to
destroy data if needed.

This patch is needed by this series, but I think it could also be
reviewed and merged standalone already.

* [PATCH 17/55] media: rkisp1: Fix sensor source pad retrieval at bound time

When a sensor is bound, its source pad is retrieved in the .bound()
operation with a call to media_entity_get_fwnode_pad(). The function
should be called with the source endpoint fwnode of the sensor, but is
instead called with the sensor's device fwnode.
Fix this, which involves storing a reference to the source endpoint
fwnode in the rkisp1_sensor_async structure, and thus implementing the
subdev notifier .destroy() operation to release the reference.

making it optional, move code related to the CSI-2 receiver to a
separate file.

Not all ISP instances include a MIPI CSI-2 receiver. To prepare for
making it optional, move code related to the CSI-2 receiver to a
separate file.

Make sure the ISP is ready to receive data before starting the CSI-2
receiver by starting it first. Similarly, stop the CSI-2 receiver before
the ISP when stopping streaming.

* [PATCH 20/55] media: rkisp1: csi: Handle CSI-2 RX configuration fully in rkisp1-csi.c

From: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
The ISP layer now calls multiple functions of the CSI-2 RX layer to
configure, start and stop it, with the steps for the last two
operations. Move those calls to rkisp1_mipi_csi2_start() and
rkisp1_mipi_csi2_stop() to simplify the ISP code and the API exposed by
the CSI-2 receiver component.

From: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
The ISP layer now calls multiple functions of the CSI-2 RX layer to
configure, start and stop it, with the steps for the last two
operations. Move those calls to rkisp1_mipi_csi2_start() and
rkisp1_mipi_csi2_stop() to simplify the ISP code and the API exposed by
the CSI-2 receiver component.

To prepare for the removal of the active_sensor field from the
rkisp1_device structure, pass the sensor pointer to the
rkisp1_csi_config() function instead of accessing it through
active_sensor.

To prepare for the removal of the active_sensor field from the
rkisp1_device structure, pass the media bus type of flag to the
rkisp1_config_cif() function instead of accessing them through
active_sensor.

From: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
To prepare for the removal of the active_sensor field from the
rkisp1_device structure, pass the media bus type of flag to the
rkisp1_config_cif() function instead of accessing them through
active_sensor.

* [PATCH 27/55] media: rkisp1: isp: Rename rkisp1_device.active_sensor to source

From: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
The active_sensor field of the rkisp1_device structure points to the ASD
data for the active source. The source may however not be a sensor, so
the naming is a bit confusing. Furthermore, the driver doesn't need to
access the full ASD from the active_sensor field, only the subdev
pointer is needed, when stopping streaming.
Rename the field to source, and turn it into a v4l2_subdev pointer.

* [PATCH 29/55] media: rkisp1: isp: Add rkisp1_device backpointer to rkisp1_isp

The rkisp1_isp structure documentation mentions a backpointer field to
rkisp1_device, but the field is missing. Add it, and use it to replace
more complicated constructs using container_of() on the v4l2_device.

The ISP_ACQ_PROP register is set twice, once in rkisp1_config_isp() for
most of its fields, and once in rkisp1_config_dvp() (called from
rkisp1_config_path()) to configure the input selection field. Move the
latter to rkisp1_config_isp() to write the register once only, and drop
the now empty rkisp1_config_dvp() function.

The rkisp1_config_isp() function stores the value of the input selection
and polarity configuration in two different local variables, OR'ed
together when writing the register. Merge them into a single acq_prop
variable.

Rename the rkisp1_get_remote_source() function to
rkisp1_isp_get_source() to use a consistent rkisp1_isp_* prefix for all
ISP functions, and drop the "remote" as the source can't be local.

* [PATCH 37/55] media: mc-entity: Add a new helper function to get a remote pad

The media_entity_remote_pad() helper function returns the first remote
pad it find connected to a given pad. Beside being possibly ill-named
(as it operates on a pad, not an entity) and non-deterministic (as it
stops at the first enabled link), the fact that it returns the first
match makes it unsuitable for drivers that need to guarantee that a
single link is enabled, for instance when an entity can process data
from one of multiple sources at a time.
For those use cases, add a new helper function,
media_entity_remote_pad_unique(), that operates on an entity and returns
a remote pad, with a guarantee that only one link is enabled. To ease
its use in drivers, also add an inline wrapper that locates source pads
specifically. A wrapper that locates sink pads can easily be added when
needed.

Shouldn't this be called media_entity_remote_source_pad_unique?
After all, it has the uniqueness constraint, but that's not reflected in the name.
With that change you can add my:

Question: of all the callers of this function, are there any that really
need media_entity_remote_pad() instead of media_pad_remote_pad_unique()?
Would it be possible to replace all callers of the old function with the
new function? If that's the case, then the _unique suffix can be dropped,
since that would effectively be the default. And if a function is needed
to handle the case where there are multiple enabled links, then a new
function should be created.
Also, media_entity_remote_pad() should really be renamed to
media_pad_remote_pad_first() or something like that, right? I'm not saying
you should, but that's really what it does, as I understand it.

I don't think so. media_entity_remote_pad() operates on a pad, switching
to media_pad_remote_pad_unique() wouldn't work on subdevs that have
multiple sink or source pads with one active link each.

Yes, I think that would make sense, and it would freethe
media_entity_remote_pad() name, so the new function wouldn't need the

I don't think so. media_entity_remote_pad() operates on a pad, switching
to media_pad_remote_pad_unique() wouldn't work on subdevs that have
multiple sink or source pads with one active link each.

Yes, I think that would make sense, and it would freethe
media_entity_remote_pad() name, so the new function wouldn't need the
_unique suffix. I'll give it a try.

The rename was easy enough, but I've decided to keep the
media_entity_remote_pad_unique() name and renamed
media_entity_remote_source_pad() to
media_entity_remote_source_pad_unique() to make the API clearer. If
those names end up being too long, we can rename them later.

The rename was easy enough, but I've decided to keep the
media_entity_remote_pad_unique() name and renamed
media_entity_remote_source_pad() to
media_entity_remote_source_pad_unique() to make the API clearer. If
those names end up being too long, we can rename them later.

Re-reading my reply, it seems I may have been mistaken. We may be able
to ditch media_pad_remote_pad_first() and replace it with
media_pad_remote_pad_unique() (at least in the majority of cases), but
we'll need to carefully review each user.

Does this need another guard here to make sure the link isn't an
ancillary link? Only likely to happen at least in the immediate future
where the entity represents a camera sensor, so possibly not applicable
here - I couldn't find where the new function is used in the series to
check. I _think_ it would actually work ok regardless...media_gobj
type-punning makes my brain ache, but I think the local_pad->entity ==
entity comparison would actually compare the entity->name member of the
entity at the end of an ancillary link to the entity parameter, not find
a match and so continue the loop without failing, but that feels a bit
sub-optimal.

Does this need another guard here to make sure the link isn't an
ancillary link? Only likely to happen at least in the immediate future
where the entity represents a camera sensor, so possibly not applicable
here - I couldn't find where the new function is used in the series to
check. I _think_ it would actually work ok regardless...media_gobj
type-punning makes my brain ache, but I think the local_pad->entity ==
entity comparison would actually compare the entity->name member of the
entity at the end of an ancillary link to the entity parameter, not find
a match and so continue the loop without failing, but that feels a bit
sub-optimal.

Or perhaps a better approach would be to provide something like a
"list_for_each_data_link()" iterator - the potential problem here (as
with Quentin's recent issue with the rkisp1 driver) is the assumption
that all links are data links, so maybe it's best to just guarantee that
if we can.

I agree with you, without a dedicated iterator, we're bound to repeat
the mistake over and over.

name it for_each_media_entity_data_link() or something similar.

I've started one - I'll send it later (using your function name though,
naming things was never my strong suit!)

I've modified this patch to skip non-data links manually, to avoid
depending on your series. If the iterator gets merged first, I'll update
the media_entity_remote_pad_unique() helper to use it.

* [PATCH 38/55] media: mc-entity: Add a new helper function to get a remote pad for a pad

The newly added media_entity_remote_source_pad() helper function handles
use cases where the entity has a link enabled uniqueness constraint
covering all pads. There are use cases where the constraint covers a
specific pad only. Add a new media_pad_remote_pad() function to handle
this. It operates as media_entity_remote_source_pad(), but on a given
pad instead of on the entity.

I'm fine with that (and for the previous patch too). I'll wait for
Sakari's opinion and will then make the change.

* [PATCH 39/55] media: rkisp1: isp: Disallow multiple active sources

The ISP supports multiple source subdevs, but can only capture from a
single one at a time. The source is selected through link setup. The
driver finds the active source in its .s_stream() handler using the
media_entity_remote_pad() function. This fails to reject invalid
configurations with multiple active sources. Fix it by using the
media_entity_remote_source_pad() helper instead, and inline
rkisp1_isp_get_source() in rkisp1_isp_s_stream() as the function is
small and has a single caller.

From: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
The ISP supports multiple source subdevs, but can only capture from a
single one at a time. The source is selected through link setup. The
driver finds the active source in its .s_stream() handler using the
media_entity_remote_pad() function. This fails to reject invalid
configurations with multiple active sources. Fix it by using the
media_entity_remote_source_pad() helper instead, and inline
rkisp1_isp_get_source() in rkisp1_isp_s_stream() as the function is
small and has a single caller.

* [PATCH 40/55] media: rkisp1: csi: Implement a V4L2 subdev for the CSI receiver

The CSI receiver is a component separate from the ISP or the resizers.
It is actually optional, not all device model include a CSI receiver. On
some SoCs CSI-2 support can be provided through an external CSI-2
receiver, connected to the ISP's parallel input.
To support those use cases, create a V4L2 subdev to model the CSI
receiver. It will allow the driver to handle both internal and external
CSI receivers the same way.
The next commit will plumb the CSI subdev to the rest of the driver,
replacing direct function calls.

Connect the CSI receiver subdevice into the rest of the driver. This
includes:
- calling the subdevice via the v4l2 subdev API
- moving the async notifier for the sensor from the ISP to the CSI
receiver
- in the ISP, create a media link to the CSI receiver, and remove the
media link creation to the sensor
- in the CSI receiver, create a media link to the sensor

'Connect the CSI subdevice between the source

Also the sketch 'Media Topology' in rkisp1-dev.c should be updated.
I'd also wonder if we should ignore src configuration of the isp entity
since it must be identical to the sink of the csi.

This is not very clear, 'source' should point to the remote source (the one outside this driver)
so why should it be 'csi.sd' ?
Or is it that now 'rkips1->source' might be either the remote source or csi? if so I think it is a bit confusing.

Now that isp should call 's_stream' for 'rkisp1->csi->sd' and not 'rkisp1->source'.
thanks,

This is not very clear, 'source' should point to the remote source (the one outside this driver)
so why should it be 'csi.sd' ?
Or is it that now 'rkips1->source' might be either the remote source or csi? if so I think it is a bit confusing.

Now that isp should call 's_stream' for 'rkisp1->csi->sd' and not 'rkisp1->source'.

Oh.
Paul, did you get so used to the fact that checkstyle.py is integrated
in git hooks in libcamera that you forgot that checkpatch.pl has to be
run manually ? :-)

I don't think so, because one could connect a parallel sensor directly
to the ISP parallel input. This isn't well supported in the driver today
though, probably because nobody has cared much about upstreaming support
for such a setup, but I think it's a valid hardware option.

rkisp1->source is the source of the ISP. it can be the CSI-2 receiver,
or if a parallel sensor is connected directly to the ISP, the sensor
itself. The check here is meant to catch bugs in the implementation
while transitioning, as in this patch external CSI-2 receivers or
parallel sensors are not supported yet. Patch "media: rkisp1: Support
the ISP parallel input" then changes this code.

As explained above, I think source is correct here, as rkisp1->csi is
the internal CSI-2 receiver, which may or may not be the source of the
ISP, depending on link configuration.

Good point, I'll do that.

Oh.
Paul, did you get so used to the fact that checkstyle.py is integrated
in git hooks in libcamera that you forgot that checkpatch.pl has to be
run manually ? :-)

I don't think so, because one could connect a parallel sensor directly
to the ISP parallel input. This isn't well supported in the driver today
though, probably because nobody has cared much about upstreaming support
for such a setup, but I think it's a valid hardware option.

rkisp1->source is the source of the ISP. it can be the CSI-2 receiver,
or if a parallel sensor is connected directly to the ISP, the sensor
itself. The check here is meant to catch bugs in the implementation
while transitioning, as in this patch external CSI-2 receivers or
parallel sensors are not supported yet. Patch "media: rkisp1: Support
the ISP parallel input" then changes this code.

As explained above, I think source is correct here, as rkisp1->csi is
the internal CSI-2 receiver, which may or may not be the source of the
ISP, depending on link configuration.

When registering the notifier, replace the manual while loop with
fwnode_graph_for_each_endpoint. This simplifies error handling.

The rkisp1 can take an input on the parallel interface. Add a port for
it, and update the required field. At least one port is required, and
both may be specified.

I don't have a real-life example of a parallel sensor connected to a
RK3399, but the i.MX8MP connects its CSI-2 receiver to the parallel
input of the ISP. I'll add an example to the other DT bindings patch
that adds the compatible string for the i.MX8MP, is that OK ?

I don't have a real-life example of a parallel sensor connected to a
RK3399, but the i.MX8MP connects its CSI-2 receiver to the parallel
input of the ISP. I'll add an example to the other DT bindings patch
that adds the compatible string for the i.MX8MP, is that OK ?

The ISP has a parallel input, exposed through port 1 in the device tree
node. While the driver supports configuring the ISP for the parallel and
BT.656 input modes, the DT parsing code, the subdev bound handler and
the ISP stream start handler only support the CSI input. Extend them to
support the parallel input.

From: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
Different ISP versions implement different sets of features. The driver
already takes the version into account in several places, but this
approach won't scale well for features that are found in different
versions. Introduce a new mechanism using a features bitmask in the
rkisp1_info structure to indicate which features the ISP support.
The first feature bit tells if the ISP has an internal CSI-2 receiver,
which is not available in all ISP versions.

Different ISP versions implement different sets of features. The driver
already takes the version into account in several places, but this
approach won't scale well for features that are found in different
versions. Introduce a new mechanism using a features bitmask in the
rkisp1_info structure to indicate which features the ISP support.
The first feature bit tells if the ISP has an internal CSI-2 receiver,
which is not available in all ISP versions.

The i.MX8MP ISP is compatbile with the rkisp1 driver. Add it to the list
of compatible strings. While at it, expand on the description of the
clocks to make it clear which clock in the i.MX8MP ISP they map to,
based on the names from the datasheet (which are confusing).

Is that public code ? Heiko, do you have any pointer to it ?
As far as I understand, this ISP IP has been forked, and is now
developed in parallel by Rockchip (for their own SoCs) and by
VeriSilicon (under the name of ISP8000Nano). The versioning schemes on
the two sides are different, and may have common roots. The fact that
the ISP8000Nano can be customized at synthesis time also complicates
this.
The question at hand is how to expose a single coherent versioning
scheme to userspace in this driver. The hardware has a version
identification register that we could use, but I don't know if it gives
us enough information (as in guaranteeing that the same version value
won't be used for different IP versions that would need to be
distinguished from each other in userspace). The fact that Rockchip and
VeriSilicon probably develop their own new versions without cooperating
increases the risk of collision.
We will also have to tackle the question of UABI. Newer ISP versions
will require extensions to the ISP parameters structure. The i.MX8MP has
extra processing blocks that are not supported by the driver today. One
option would be to duplicate the top-level rkisp1_params_cfg structure
per ISP version, as well as a set of lower-level structure where
appropriate (how to handle that easily and efficiently on the driver
side will be interesting to figure out). Another option is to only add
parameters to the end of the rkisp1_params_cfg structure, but I fear
that won't scale. We'll end up with a large structure where lots of data
will be irrelevant for any particular ISP version, and that will be
error-prone.
Comments and idea will be appreciated.

Thinking out loud:
The most sure way is clearly to have feature flags for each feature.
Maybe one set of internal ones that only affect the driver, and another
set for userspace to see what the hardware is capable of. On the other
hand, from the top of my head, the ones that userspace cares about could
be probed in other ways, like the presence of the self path can be
obtained from the media graph, and available controls/formats from...
the list of available controls/formats.
Also if we have flags then... what's the point of the version number? Is
there any value in letting userspace know some version number if it
doesn't particularly correlate with the actual features that are
available? Plus, we run the risk of version numbers (from the version
register) colliding between VeriSilicon and Rockchip. Plus my
understanding is that the current version number that we have right now
(V10 ~ V13) is fairly arbitrary anyway? (but we have to keep it for
compatibility reasons.)
So...
1 - Do we need a precise version number for the purpose of probing
capabilities? Can it just be replaced with feature flags?
2 - Do we need feature flags? Can all information (that userspace cares
about be obtained by some other source? (I guess this needs more
investigation)
3 - Maybe userspace doesn't care about the precise version number at
all? We could just continue with an aribitrary version number (like
IMX_V10)?
4 - Or we could just expand the version number with what we get from the
version register? And have different... labels (?) based on the vendor?
Lots of thinking out loud with no clear conclusion :D

Thinking out loud:
The most sure way is clearly to have feature flags for each feature.
Maybe one set of internal ones that only affect the driver, and another
set for userspace to see what the hardware is capable of. On the other
hand, from the top of my head, the ones that userspace cares about could
be probed in other ways, like the presence of the self path can be
obtained from the media graph, and available controls/formats from...
the list of available controls/formats.
Also if we have flags then... what's the point of the version number? Is
there any value in letting userspace know some version number if it
doesn't particularly correlate with the actual features that are
available? Plus, we run the risk of version numbers (from the version
register) colliding between VeriSilicon and Rockchip. Plus my
understanding is that the current version number that we have right now
(V10 ~ V13) is fairly arbitrary anyway? (but we have to keep it for
compatibility reasons.)
So...
1 - Do we need a precise version number for the purpose of probing
capabilities? Can it just be replaced with feature flags?
2 - Do we need feature flags? Can all information (that userspace cares
about be obtained by some other source? (I guess this needs more
investigation)
3 - Maybe userspace doesn't care about the precise version number at
all? We could just continue with an aribitrary version number (like
IMX_V10)?
4 - Or we could just expand the version number with what we get from the
version register? And have different... labels (?) based on the vendor?
Lots of thinking out loud with no clear conclusion :D

The i.MX8MP has a gasket between the CSI-2 receiver and the ISP.
Configure and enable it when starting the ISP, and disable it when
stopping.

that is currently not handled. Add a feature flag to determine which
type of crop the ISP supports and set the crop registers based on that.

The ISP version in the i.MX8MP has a set of registers currently not
handled by the driver for output size configuration. Add a feature flag
to determine if the ISP requires this, and set the registers based on
that.

On the ISP that is integrated in the i.MX8MP, the DMA base addresses are
encoded in 34-bit. Shift them to the left by 2 bits so that they can be
contained in 32 bits.

Hi Paul,
Thank you for the patch.

The important part here is that this is how the address is encoded in
the hardware. I suppose it's obvious, otherwise it woudln't work at all,
but maybe it could be explained more explicitly ?
On the ISP that is integrated in the i.MX8MP, DMA addresses have been
extended to 34 bits, with the 32 MSBs stored in the DMA address
registers and the 2 LSBs set to 0. Shift the buffer addresses right by 2
on that platform.

Hi Paul,
Thank you for the patch.

The important part here is that this is how the address is encoded in
the hardware. I suppose it's obvious, otherwise it woudln't work at all,
but maybe it could be explained more explicitly ?
On the ISP that is integrated in the i.MX8MP, DMA addresses have been
extended to 34 bits, with the 32 MSBs stored in the DMA address
registers and the 2 LSBs set to 0. Shift the buffer addresses right by 2
on that platform.

If the 32 MSB are all stored in the in the dma address then why do we
need to shift?

On Rokchip SoCs the DMA address is 32-bit wide, and stored as-is in the
registers. On i.MX8MP, the DMA address is 34-bit, and must be aligned to
a multiple of 4 bytes, so the two LSBs are guaranteed to be 0. The DMA
registers are still 32-bit wide, and store bits [33:2] of the DMA
addresses, hence the shift.

On Rokchip SoCs the DMA address is 32-bit wide, and stored as-is in the
registers. On i.MX8MP, the DMA address is 34-bit, and must be aligned to
a multiple of 4 bytes, so the two LSBs are guaranteed to be 0. The DMA
registers are still 32-bit wide, and store bits [33:2] of the DMA
addresses, hence the shift.

The ISP that is integrated in the i.MX8MP uses different bits in the
MRSZ_CTRL and SRSZ_CTRL registers for updating the configuration
compared to the on in the RK3399. In addition, it adds a new bit for
enabling crop. Add new definitions for these bits for i.MX8MP devices,
and update where they are set.

* [PATCH 55/55] media: rkisp1: Fix RSZ_CTRL bits for i.MX8MP

The ISP that is integrated in the i.MX8MP uses different bits in the
MRSZ_CTRL and SRSZ_CTRL registers for updating the configuration
compared to the on in the RK3399. In addition, it adds a new bit for
enabling crop. Add new definitions for these bits for i.MX8MP devices,
and update where they are set.

Does it make sense to move this kind of information into struct rkisp1_info?
This way you can skip the if (isp_ver == ...) thing.

Good question. Paul, what do you think ? If it doesn't get moved to the
structure, I think I'd condition it by the RKISP1_FEATURE_RSZ_CROP
feature bit instead of a version check, as it seems closely related. I'm
actually leaning towards the latter.

Hi Paul,
Thank you for the patches.

I have a few questions about the i.MX8MP support (the main one being
about the version numbering scheme), which I'll ask in replies to the
corresponding patches. Patches 01/55 to 46/55 could be merged already,
once reviewed of course. As the series is large, let's see if we can
motivate any reviewer :-)

I have a few questions about the i.MX8MP support (the main one being
about the version numbering scheme), which I'll ask in replies to the
corresponding patches. Patches 01/55 to 46/55 could be merged already,
once reviewed of course. As the series is large, let's see if we can
motivate any reviewer :-)
