[cip-dev] [PATCH 4.19.y-cip 01/40] media: ov5645: Remove unneeded regulator_set_voltage()

[Lad Prabhakar]

[-- Attachment #1: Type: text/plain, Size: 2525 bytes --]

From: Fabio Estevam <festevam@gmail.com>

commit 45ffbd15ede6add6e4fb150e4bab7a27cfe62552 upstream.

There is no need to call regulator_set_voltage() for each regulator
that powers the camera.

The voltage value for each regulator should be retrieved from the
device tree, so remove the unneeded regulator_set_voltage().

[cip-dev] [PATCH 4.19.y-cip 02/40] media: device property: Add a function to test is a fwnode is a graph endpoint

[Lad Prabhakar]

[-- Attachment #1: Type: text/plain, Size: 1708 bytes --]

From: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>

commit 35694afc92646ac24d7f3ef34a7387876d998fe7 upstream.

Drivers may need to test if a fwnode is a graph endpoint. To avoid
hand-written solutions that wouldn't work for all fwnode types, add a
new fwnode_graph_is_endpoint() function for this purpose. We don't need
to wire it up to different backends for OF and ACPI for now, as the
implementation can simply be based on checkout the presence of a
remote-endpoint property.

[cip-dev] [PATCH 4.19.y-cip 03/40] media: v4l2-async: Accept endpoints and devices for fwnode matching

[Lad Prabhakar]

[-- Attachment #1: Type: text/plain, Size: 3437 bytes --]

From: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>

commit b98158d837efa0b2f2f59ee2ff77f4791f978d74 upstream.

fwnode matching was designed to match on nodes corresponding to a
device. Some drivers, however, needed to match on endpoints, and have
passed endpoint fwnodes to v4l2-async. This works when both the subdev
and the notifier use the same fwnode types (endpoint or device), but
makes drivers that use different types incompatible.

Fix this by extending the fwnode match to handle fwnodes of different
types. When the types (deduced from the presence of remote endpoints)
are different, retrieve the device fwnode for the side that provides an
endpoint fwnode, and compare it with the device fwnode provided by the
other side. This allows interoperability between all drivers, regardless
of which type of fwnode they use for matching.

[cip-dev] [PATCH 4.19.y-cip 04/40] media: v4l2-async: Pass notifier pointer to match functions

[Lad Prabhakar]

[-- Attachment #1: Type: text/plain, Size: 3371 bytes --]

From: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>

commit 3e33392a9561fd64515049317041646ab3bf32aa upstream.

The notifier is useful to match functions to access information about
the device matching a subdev. This will be used to print messages using
the correct struct device and driver name.

[cip-dev] [PATCH 4.19.y-cip 05/40] media: v4l2-async: Log message in case of heterogeneous fwnode match

[Lad Prabhakar]

[-- Attachment #1: Type: text/plain, Size: 2521 bytes --]

From: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com>

commit e80cdf0a3843fe570c891cb976feb0c136b19fb7 upstream.

When a notifier supplies a device fwnode and a subdev supplies an
endpoint fwnode, incorrect matches may occur if multiple subdevs
correspond to the same device fwnode. This can't be handled
transparently in the framework, and requires the notifier to switch to
endpoint fwnodes. Log a message to notify of this problem. A second
message is added to help accelerating the transition to endpoint
matching.

[cip-dev] [PATCH 4.19.y-cip 06/40] media: v4l: ctrl: Provide unlocked variant of v4l2_ctrl_grab

[Lad Prabhakar]

[-- Attachment #1: Type: text/plain, Size: 3366 bytes --]

From: Sakari Ailus <sakari.ailus@linux.intel.com>

commit 7a9b109d91cfc6089006378efd515cc287bdef67 upstream.

Sometimes it may be necessary to grab a control while holding the control
handler's lock. Provide an unlocked variant of v4l2_ctrl_grab for the
purpose --- it's called __v4l2_ctrl_grab.

[cip-dev] [PATCH 4.19.y-cip 07/40] media: rcar-vin: fix wrong return value in rvin_set_channel_routing()

[Lad Prabhakar]

[-- Attachment #1: Type: text/plain, Size: 1261 bytes --]

From: Niklas Söderlund <niklas.soderlund+renesas@ragnatech.se>

commit 8d19d5d03b4d09177b0ae87f964eb751e6f51b7b upstream.

If the operation in rvin_set_channel_routing() is successful the 'ret'
variable contains the runtime PM use count for the VIN master device.
The intention is not to return the use count to the caller but to return
0 on success else none zero.

Fix this by always returning 0 if the operation is successful.

[cip-dev] [PATCH 4.19.y-cip 09/40] media: rcar-vin: Invalidate pipeline if conversion is not possible on input formats

[Lad Prabhakar]

[-- Attachment #1: Type: text/plain, Size: 1616 bytes --]

commit fd22e8eb4145852223b36b0e6c7e308ed5905ad2 upstream.

Up until now the VIN was capable to convert any of its supported input mbus
formats to any of it's supported output pixel formats. With the addition of
RAW formats this is no longer true.

This patch invalidates the pipeline by adding a check if given vin input
format can be converted to supported output pixel format.

[cip-dev] [PATCH 4.19.y-cip 13/40] media: i2c: Add driver for Sony IMX219 sensor

[Lad Prabhakar]

[-- Attachment #1: Type: text/plain, Size: 37067 bytes --]

From: Dave Stevenson <dave.stevenson@raspberrypi.com>

commit 1283b3b8f82b9004fbb94398cade5c8e797a2c8d upstream.

Adds a driver for the 8MPix Sony IMX219 CSI2 sensor.
Whilst the sensor supports 2 or 4 CSI2 data lanes, this driver
currently only supports 2 lanes.
8MPix @ 15fps, 1080P @ 30fps (cropped FOV), and 1640x1232 (2x2 binned)
@ 30fps are currently supported.

[cip-dev] [PATCH 4.19.y-cip 14/40] media: i2c: imx219: Fix power sequence

[Lad Prabhakar]

[-- Attachment #1: Type: text/plain, Size: 2074 bytes --]

commit ca45448a56659c6df6e0436188e97f6cc65dea8a upstream.

When supporting Rpi Camera v2 Module on the RZ/G2E, found the driver had
some issues with rcar mipi-csi driver. The sensor never entered into LP-11
state.

The powerup sequence in the datasheet[1] shows the sensor entering into
LP-11 in streaming mode, so to fix this issue transitions are performed
from "streaming -> standby" in the probe() after power up.

With this commit the sensor is able to enter LP-11 mode during power up,
as expected by some CSI-2 controllers.

[cip-dev] [PATCH 4.19.y-cip 17/40] media: i2c: imx219: Implement get_selection

[Lad Prabhakar]

[-- Attachment #1: Type: text/plain, Size: 5328 bytes --]

From: Jacopo Mondi <jacopo@jmondi.org>

commit e6d4ef7d58aa7e64aa735e1b3c7b670e4fb34d6f upstream.

Implement the get_selection pad operation for the IMX219 sensor driver.
The supported targets report the sensor's native size, the crop default
rectangle and the crop rectangle.

[cip-dev] [PATCH 4.19.y-cip 18/40] media: i2c: imx219: Fix a bug in imx219_enum_frame_size

[Lad Prabhakar]

[-- Attachment #1: Type: text/plain, Size: 1463 bytes --]

From: Dafna Hirschfeld <dafna.hirschfeld@collabora.com>

commit b2bbf1aac61186ef904fd28079e847d3feadb89e upstream.

When enumerating the frame sizes, the value sent to
imx219_get_format_code should be fse->code
(the code from the ioctl) and not imx219->fmt.code
which is the code set currently in the driver.

[cip-dev] [PATCH 4.19.y-cip 19/40] media: i2c: imx219: Selection compliance fixes

[Lad Prabhakar]

[-- Attachment #1: Type: text/plain, Size: 2755 bytes --]

From: Hans Verkuil <hverkuil-cisco@xs4all.nl>

commit 1ed36ecd1459b653cced8929bfb37dba94b64c5d upstream.

To comply with the intended usage of the V4L2 selection target when
used to retrieve a sensor image properties, adjust the rectangles
returned by the imx219 driver.

The top/left crop coordinates of the TGT_CROP rectangle were set to
(0, 0) instead of (8, 8) which is the offset from the larger physical
pixel array rectangle. This was also a mismatch with the default values
crop rectangle value, so this is corrected. Found with v4l2-compliance.

While at it, add V4L2_SEL_TGT_CROP_BOUNDS support: CROP_DEFAULT and
CROP_BOUNDS have the same size as the non-active pixels are not readable
using the selection API. Found with v4l2-compliance.

[reword commit message, use macros for pixel offsets]

[cip-dev] [PATCH 4.19.y-cip 20/40] media: i2c: imx219: take lock in imx219_enum_mbus_code/frame_size

[Lad Prabhakar]

[-- Attachment #1: Type: text/plain, Size: 4658 bytes --]

From: Hans Verkuil <hverkuil-cisco@xs4all.nl>

commit 81015221a269e0d9bf6dbc3fda099b09a876ebb7 upstream.

These two functions did not take the imx219->mutex lock, but
imx219_get_format_code checks that a lock is taken, so it issues
a warning:

[cip-dev] [PATCH 4.19.y-cip 21/40] arm64: dts: renesas: r8a774c0-cat874: Add support for AISTARVISION MIPI Adapter V2.1

[Lad Prabhakar]

[-- Attachment #1: Type: text/plain, Size: 6235 bytes --]

commit 0e36587c0832af5df894f5e5fcc45fb5a05cea5b upstream.

This patch adds support for AISTARVISION MIPI Adapter V2.1 board connected
to G2E board. Common file aistarvision-mipi-adapter-2.1.dtsi is created
which have the camera endpoint nodes for imx219 and ov5645 so that this can
be re-used with other G2x platforms.

r8a774c0-ek874-mipi-2.1.dts file enables the required VIN/CSI nodes and by
default ties ov5645 camera endpoint to CSI2.

[cip-dev] [PATCH 4.19.y-cip 25/40] media: rcar-csi2: Enable support for r8a774a1

[Lad Prabhakar]

[-- Attachment #1: Type: text/plain, Size: 1308 bytes --]

From: Biju Das <biju.das@bp.renesas.com>

commit d4b87d459a4cfc8009ec4ee92893d84cef277f61 upstream.

Add the MIPI CSI-2 driver support for RZ/G2M(r8a774a1) SoC.
The CSI-2 module of RZ/G2M is similar to R-Car M3-W.

[cip-dev] [PATCH 4.19.y-cip 37/40] arm64: dts: renesas: aistarvision-mipi-adapter-2.1: Add parent macro for each sensor

[Lad Prabhakar]

[-- Attachment #1: Type: text/plain, Size: 1985 bytes --]

commit 622007d172fbb1d7556329bafd72dc28c0baf1b8 upstream.

For HiHope RZ/G2H the OV5645 sensor is populated on i2c2 whereas the imx219
sensor is populated on i2c3 so add support for handling such cases by
adding a parent macro for each sensor.

Also update r8a774c0-ek874-mipi-2.1.dts to incorporate the changes.

[cip-dev] [PATCH 4.19.y-cip 38/40] arm64: dts: renesas: Add support for MIPI Adapter V2.1 connected to HiHope RZ/G2H

[Lad Prabhakar]

[-- Attachment #1: Type: text/plain, Size: 4695 bytes --]

commit 05e6ae33cf9834dd2f0ff35001828ca09fe5af26 upstream.

Add support for AISTARVISION MIPI Adapter V2.1 board connected to HiHope
RZ/G2H board.

Common file hihope-rzg2-ex-aistarvision-mipi-adapter-2.1.dtsi is created
which will be used by RZ/G2{HMN}, by default the CSI20 node is tied to
ov5645 camera endpoint and the imx219 camera endpoint is tied to CSI40.

I assume it is 0.25 inch sensor? 1/4 inch or 0.25 inch would be
understandable, but 1/4.0 is kind of strange.

"V" should be uppercase in voltages.

I believe this should be "us" or "usec".

This is not really english.

That's really interesting piece of code. len is in bytes, but return
value is in 32 bit values, magic with be32...

Wow. When I thought above was interesting.... this is even more so.

Is this usual for other cameras? Will not it cause problems to

ctrl->val is unused in this case?

Is it correct/vital that one error path uses put_noidle() and second
uses plain put()?

This error path will leave driver in inconsistent state. hflip/vflip
controls will be locked and pm_runtime_put() is not executed.

Is it correct to call endpoint_free on error pointer?

This needs to be normal comment style, and it needs to contain
sentences. And it may be better to provide #ifdef for the alternate
configuration.

Re: [cip-dev] [PATCH 4.19.y-cip 00/40] Renesas RZ/G2{E,H,M,N} add VIN, CSI2 support

[Pavel Machek]

[-- Attachment #1.1: Type: text/plain, Size: 395 bytes --]

Hi!

I had some minor comments, but the series looks good; I guess we don't
need to delay applying.

Some of the patches are not in 5.10, so we'll need them in cip 5.10
branch, too?

Let me do some testing.

Best regards,
								Pavel

Well... test are okay, except that Renesas lab is offline so it was
not really tested on Renesas targets.

Anyway, I guess I'm okay with applying these if there are no other
comments.

I reviewed this series, I didn't see any major problems.
As Paval points out, the Renesas lab is now stopped.
If this recovers and the target hardware test is okay, I would apply this.

It is refered as "Type 1/4.0" and I'm not really sure what it means.

1/4 inch is 6.35mm, but document states it is 4.6mm.

https://www.photoreview.com.au/tips/buying/unravelling-sensor-sizes/
explains this system, but they use 1/4", not 1/4.0, and it translates
that to 4.5mm.

I guess easiest way is to say it is "4.8mm CMOS active pixel digital
image sensor" and forget about confusing inch values.

Best regards,
								Pavel

Thanks for the pointer.

Totally agree with you (^^4.5mm).

Sorry about the lab-cip-renesas issues. The lab will probably be offline until next week.
I'm happy for this series to be delayed until it's tested if that's what you'd prefer.
