Hi,
Here's version 3 of the DSS DT series.
The previous version can be found from:
v1: http://permalink.gmane.org/gmane.linux.ports.arm.omap/108249
v2: http://permalink.gmane.org/gmane.linux.ports.arm.omap/108866
The main changes to v2 are:
- DT Binding documentation
- OMAP2 DSS support
- Split DSI register space
- DSS nodes disabled by default
- Hack to have generic DT bindings but OMAP specific drivers (for now)
This series can also be found from:

omapdss driver uses a omapdss platform device to pass platform specific
function pointers and DSS hardware version from the arch code to the
driver. This device is needed also when booting with DT.
This patch adds omapdss_init_of() function, called from board-generic at
init time, which creates the omapdss device.

omapdss driver uses a omapdss platform device to pass platform specific
function pointers and DSS hardware version from the arch code to the
driver. This device is needed also when booting with DT.
This patch adds omapdss_init_of() function, called from board-generic at
init time, which creates the omapdss device.

As there is no common panel framework in the kernel, we have OMAP
specific panel drivers. However, the DT data should be generic. This
brings the issue that some other platform could use the same panels, and
would need to create a driver with the same 'compatible' string as the
OMAP driver.
In the long run, we have to get a common panel framework. For the time
being, this patch solves the issue:
At early boot time, we go through the DT nodes looking for the panels
the kernel supports for OMAP. For each found node, the 'compatible'
string is prepended with "omapdss,", i.e. "sony,acx565akm" becomes
"omapdss,sony,acx565akm". The OMAP display drivers all have "omapdss,"
at the beginning of their compatible field.
This allows us to have generic DT data, but OMAP specific display
drivers.

* [PATCHv3 02/41] ARM: OMAP2+: DT 'compatible' tweak for displays
@ 2014-01-21 10:56 ` Tomi Valkeinen

As there is no common panel framework in the kernel, we have OMAP
specific panel drivers. However, the DT data should be generic. This
brings the issue that some other platform could use the same panels, and
would need to create a driver with the same 'compatible' string as the
OMAP driver.
In the long run, we have to get a common panel framework. For the time
being, this patch solves the issue:
At early boot time, we go through the DT nodes looking for the panels
the kernel supports for OMAP. For each found node, the 'compatible'
string is prepended with "omapdss,", i.e. "sony,acx565akm" becomes
"omapdss,sony,acx565akm". The OMAP display drivers all have "omapdss,"
at the beginning of their compatible field.
This allows us to have generic DT data, but OMAP specific display
drivers.

Add support to get the label (i.e. a "nickname") for a display from the
DT data. If there is no label defined, use the display's alias (e.g.
'display0') as a name.

We currently create a "displayX" style alias name for all displays,
using a number that is incremented for each registered display. With the
new DSS device model there is no clear order in which the displays are
registered, and thus the numbering is somewhat random.
This patch improves the behavior for DT case so that if the displays
have been assigned DT aliases, those aliases will be used as DSS
aliases.
This means that "display0" is always the one specified in the DT alias,
and thus display0 can be used as default display in case the user didn't
specify a default display.

The regulator names used for DSS components are somewhat ugly for DT
use. As we're just adding DT support, it's simple to change the
regulator names.
This patch makes the DSS driver get the regulators with somewhat cleaner
names. For example, this allows us to define HDMI's VDDA regulator in
the DT data as:
vdda-supply = <...>;
instead of
vdda_hdmi_dac-supply = <...>;
The code also still tries to get the regulators with the old names, if
the regulator_get with the new names fail. This keep backward
compatibility, and can be removed after we have moved to DT.

Add DT support for DSS. Contrary to the non-DT version, the DSS in DT
mode contains DPI and SDI outputs, which better reflects the hardware.
The non-DT code will be removed after all boards have been converted to
DT, so there's no need to change the non-DT code to act the same way.
The code for DPI and SDI needs to be refined later to make it possible
to add multiple DPI ports. For now, handling just a single DPI port is
enough for all the boards.

Add DT support for DSS. Contrary to the non-DT version, the DSS in DT
mode contains DPI and SDI outputs, which better reflects the hardware.
The non-DT code will be removed after all boards have been converted to
DT, so there's no need to change the non-DT code to act the same way.
The code for DPI and SDI needs to be refined later to make it possible
to add multiple DPI ports. For now, handling just a single DPI port is
enough for all the boards.

Add DT support to VENC.
In contrast to non-DT version, the DT version gets the invert-polarity
and connector type via venc's endpoint, not from the connector.

Add the code to make the DSI driver work with device tree on OMAP3 and
OMAP4.
A minor hack is needed at the moment in the DSI driver: the DSS driver
needs to know the ID number of a DSI device, as clocks are routed in
different ways to the DSI devices. At the moment we don't have any
proper way to manage this, so this patchs adds a simple lookup table
that is used to deduce the ID from the DSI device's base address.

Add DT data for OMAP4 display subsystem, which contains the following
blocks:
dss - the wrapper/glue for the display modules
dispc - display controller
dsi - MIPI DSI encoder (two independent modules)
rfbi - MIPI DBI encoder
venc - analog TV encoder
hdmi - HDMI encoder

For booting Panda and 4430SDP with DT, while DSS did not support DT, we
had to had small hacks in the omapdss driver to get the regulators. With
DT now supported in DSS, we can remove those hacks.

+Texas Instruments OMAP Display Subsystem
+========================================
+
+Generic Description
+-------------------
+
+This document is a generic description of the OMAP Display Subsystem bindings.
+Binding details for each OMAP SoC version are described in respective binding
+documentation.
+
+The OMAP Display Subsystem (DSS) hardware consists of DSS Core, DISPC module and
+a number of encoder modules. All DSS versions contain DSS Core and DISPC, but
+the encoder modules vary.
+
+The DSS Core is the parent of the other DSS modules, and manages clock routing,
+integration to the SoC, etc.
+
+DISPC is the display controller, which reads pixels from the memory and outputs
+a RGB pixel stream to encoders.
+
+The encoder modules encode the received RGB pixel stream to a video output like
+HDMI, MIPI DPI, etc.
+
+Video Ports
+-----------
+
+The DSS Core and the encoders have video port outputs. The structure of the
+video ports is described in Documentation/devicetree/bindings/video/video-
+ports.txt, and the properties for the ports and endpoints for each encoder are
+described in the SoC's DSS binding documentation.
+
+The video ports are used to describe the connections to external hardware, like
+panels or external encoders.
+
+Aliases
+-------
+
+The board dts file may define aliases for displays to assign "displayX" style
+name for each display. If no aliases are defined, a semi-random number is used
+for the display.
+
+Example
+-------
+
+A shortened example of the DSS description for OMAP4, with non-relevant parts
+removed, defined in omap4.dtsi:
+
+dss: dss@58000000 {
+ compatible = "ti,omap4-dss", "simple-bus";
+ reg = <0x58000000 0x80>;
+ status = "disabled";
+ ti,hwmods = "dss_core";
+ #address-cells = <1>;
+ #size-cells = <1>;
+ ranges;
+
+ dispc@58001000 {
+ compatible = "ti,omap4-dispc";
+ reg = <0x58001000 0x1000>;
+ interrupts = <GIC_SPI 25 IRQ_TYPE_LEVEL_HIGH>;
+ ti,hwmods = "dss_dispc";
+ };

+};
+
+A shortened example of the board description for OMAP4 Panda board, defined in
+omap4-panda.dts.
+
+The Panda board has a DVI and a HDMI connector, and the board contains a TFP410
+chip (MIPI DPI to DVI encoder) and a TPD12S015 chip (HDMI ESD protection & level
+shifter). The video pipelines for the connectors are formed as follows:

+OMAP HDMI --(HDMI)--> TPD12S015 --(HDMI)--> HDMI COnnector

+Video Ports
+===========
+
+The video port bindings used for display devices is a superset of the v4l2 video
+ports described here:
+
+Documentation/devicetree/bindings/media/video-interfaces.txt
+
+The only difference is a more compact way to describe devices with only one
+endpoint. In cases like that, the 'ports' and 'port' nodes are not needed. For
+example, a DPI panel with a single input endpoint:
+
+lcd0: display@0 {
+ compatible = "samsung,lte430wq-f0c", "panel-dpi";
+
+ lcd_in: endpoint {
+ remote-endpoint = <&dpi_out>;
+ };
+};
+
+The rest of the bindings are the same as in v4l2 video port bindings and not
+described here.

+Video Ports
+=====+
+The video port bindings used for display devices is a superset of the v4l2 video
+ports described here:
+
+Documentation/devicetree/bindings/media/video-interfaces.txt
+
+The only difference is a more compact way to describe devices with only one
+endpoint. In cases like that, the 'ports' and 'port' nodes are not needed. For
+example, a DPI panel with a single input endpoint:
+
+lcd0: display@0 {
+ compatible = "samsung,lte430wq-f0c", "panel-dpi";
+
+ lcd_in: endpoint {
+ remote-endpoint = <&dpi_out>;
+ };
+};
+
+The rest of the bindings are the same as in v4l2 video port bindings and not
+described here.

+Texas Instruments OMAP Display Subsystem
+========================================
+
+Generic Description
+-------------------
+
+This document is a generic description of the OMAP Display Subsystem bindings.
+Binding details for each OMAP SoC version are described in respective binding
+documentation.
+
+The OMAP Display Subsystem (DSS) hardware consists of DSS Core, DISPC module and
+a number of encoder modules. All DSS versions contain DSS Core and DISPC, but
+the encoder modules vary.
+
+The DSS Core is the parent of the other DSS modules, and manages clock routing,
+integration to the SoC, etc.
+
+DISPC is the display controller, which reads pixels from the memory and outputs
+a RGB pixel stream to encoders.
+
+The encoder modules encode the received RGB pixel stream to a video output like
+HDMI, MIPI DPI, etc.
+
+Video Ports
+-----------
+
+The DSS Core and the encoders have video port outputs. The structure of the
+video ports is described in Documentation/devicetree/bindings/video/video-
+ports.txt, and the properties for the ports and endpoints for each encoder are
+described in the SoC's DSS binding documentation.
+
+The video ports are used to describe the connections to external hardware, like
+panels or external encoders.
+
+Aliases
+-------
+
+The board dts file may define aliases for displays to assign "displayX" style
+name for each display. If no aliases are defined, a semi-random number is used
+for the display.
+
+Example
+-------
+
+A shortened example of the DSS description for OMAP4, with non-relevant parts
+removed, defined in omap4.dtsi:
+
+dss: dss at 58000000 {
+ compatible = "ti,omap4-dss", "simple-bus";
+ reg = <0x58000000 0x80>;
+ status = "disabled";
+ ti,hwmods = "dss_core";
+ #address-cells = <1>;
+ #size-cells = <1>;
+ ranges;
+
+ dispc at 58001000 {
+ compatible = "ti,omap4-dispc";
+ reg = <0x58001000 0x1000>;
+ interrupts = <GIC_SPI 25 IRQ_TYPE_LEVEL_HIGH>;
+ ti,hwmods = "dss_dispc";
+ };
+
+ hdmi: encoder at 58006000 {
+ compatible = "ti,omap4-hdmi";
+ reg = <0x58006000 0x200>,
+ <0x58006200 0x100>,

+Video Ports
+===========
+
+The video port bindings used for display devices is a superset of the v4l2 video
+ports described here:
+
+Documentation/devicetree/bindings/media/video-interfaces.txt
+
+The only difference is a more compact way to describe devices with only one
+endpoint. In cases like that, the 'ports' and 'port' nodes are not needed. For
+example, a DPI panel with a single input endpoint:
+
+lcd0: display at 0 {
+ compatible = "samsung,lte430wq-f0c", "panel-dpi";
+
+ lcd_in: endpoint {
+ remote-endpoint = <&dpi_out>;
+ };
+};
+
+The rest of the bindings are the same as in v4l2 video port bindings and not
+described here.

Thanks. Shouldn't make trivial changes, and then not run a full

I fixed the issues and pushed the branch again to work/dss-dt-review-3.
The fixes are minor, so the already posted series can be reviewed.

Can you have a look at the arch/arm/ parts in the series and ack if
they're ok, i.e, patches 1, 2, 32.
Then there are the .dts patches, 22-30, for which I haven't been able to
get any acks. I'm not sure who I should get acks from for those, but I
don't mind adding yours if you want to give it.
The .dts patches have had minor changes compared to the ones posted
here, according to the DT bindings review comments, but nothing much has
changed.

Patches 1, 2 & 32 look OK to me, so for those please feel free to add:

There's a minor merge conflict in pdata-quirks.c, but that's trivial
so it should be OK for you to queue those along with the DSS patches.

These will cause unnecessary merge conflicts all over the place:

How about do a pull request for just the .dts changes against current
omap-for-v3.15/dt branch ASAP for me so I can pull it in? That is assuming
that just the .dts changes alone won't break anything.
Then make sure your series works both ways and maybe do a follow up
patch that flips things over after the dependencies are merged.

Unfortunately they do break. At least pinmuxing is moved from the global
definitions to be handled by the respective display drivers, and there
are some regulator_name hacks that the DT patches remove.
I think those changes could be removed from my patches, and then added
back later when everything else has been merged.
The bigger issue is that suddenly there's lots of discussion about the
display DT bindings. If those are not resolved very soon, I guess I have
no choice but to again skip the merge window for the DSS DT changes.

OK. Will that cause regressions for omap3 as that's still also booting
in legacy mode?

Or you could have a second branch that also merges in omap-for-v3.15/dt
branch that you can send later towards the merge window after the arm-soc
changes have been merged. If you want to do that, then feel free to add
my ack also for the .dts changes:
Acked-by: Tony Lindgren <tony@atomide.com>
If however those changes get postponed to v3.16, it's best that you'll
redo the branch as I'm sure we'll have other merge issues for v3.16.

OK, some of these more bindings can take easily six months to reach
some kind of resolution. You may be able to use TI specific unstable
bindings meanwhile if that makese sense.

OK. Will that cause regressions for omap3 as that's still also booting
in legacy mode?

Or you could have a second branch that also merges in omap-for-v3.15/dt
branch that you can send later towards the merge window after the arm-soc
changes have been merged. If you want to do that, then feel free to add
my ack also for the .dts changes:

If however those changes get postponed to v3.16, it's best that you'll
redo the branch as I'm sure we'll have other merge issues for v3.16.

OK, some of these more bindings can take easily six months to reach
some kind of resolution. You may be able to use TI specific unstable
bindings meanwhile if that makese sense.

No, I don't think so. The problems revolve around the pdata-quirks, with
current DSS support when booting with DT. It's rather difficult to split
the series so that it could be merged freely in multiple parts.
If I split the series into three parts: 1) .dts changes 2) main DSS DT
changes 3) removal of pdata-quirks etc, I run into problems. Both 1) and
2) work fine individually, but when both are merged, there are two
competing systems, the proper DT stuff and the pdata-quirks stuff. And I
haven't found out a simple way to manage that, as the whole display
support is split into multiple independent devices.
One option would be to combine 1) and 3), so that when they are merged,
there would be proper DT data, and the pdata-quirks would be removed so
that it wouldn't be messing everything up. But that would, of course,
mean that after merging 1+3, the display wouldn't work on those boards
that rely on pdata-quirks, until 2) is merged.

Ok. At the moment I feel that the easiest option would be to keep the
DSS DT series as it is, but merge omap-for-v3.15/dt to it and solve the
conflicts. I'd keep that branch separate from the fbdev changes, so that
I could send the DSS DT pull request later, when arm-soc has been pulled.

Yep. I don't know... If the whole port/endpoint system that I currently
use is changed totally, it might be painful to support both the TI
specific bindings with the old format and the newer format.

Looks like this patch did not get merged or am I missing
something?
As you probably are aware, we have at least these boards
needing it before we can remove the omap3 legacy support:
board-am3517evm.c
board-cm-t35.c
board-devkit8000.c
board-ldp.c
board-overo.c
We could probably set the display timings based on the
compatible flag in the driver if that's an issue?
And then board-omap3pandora.c also needs support for
panel_tpo_td043mtea1_platform_data.

Tony

Looks like this patch did not get merged or am I missing
something?
As you probably are aware, we have at least these boards
needing it before we can remove the omap3 legacy support:
board-am3517evm.c
board-cm-t35.c
board-devkit8000.c
board-ldp.c
board-overo.c
We could probably set the display timings based on the
compatible flag in the driver if that's an issue?
And then board-omap3pandora.c also needs support for
panel_tpo_td043mtea1_platform_data.

Yes, I dropped it. None of the boards that I converted used panel-dpi.
There was so much discussions about the display bindings, so I thought
it's better to leave out all but the needed patches.

The timings shouldn't be an issue. But there's the backlight GPIO,
currently handled by panel-dpi, which should be removed from the panel.
We should use gpio-backlight for that one.

Yep, there's still much to do for DSS DT support. Hopefully it will be
easier now that the core support is there. I'll continue working on the
remaining boards and panels. However, I don't have any of the remaining
boards, so help is of course appreciated.

Using gpio-backlight makes sense for sure.
FYI, in the case of the LDP there are four GPIOs to configure to
get things going:
gpio55 LCD RESET panel-dpi?
gpio56 LCD QVGA panel-dpi?
twl gpio7 LCD power panel-dpi
twl gpio15 LCD backlight gpio-backlight

Yeah I can test at least the LDP here.

Using gpio-backlight makes sense for sure.
FYI, in the case of the LDP there are four GPIOs to configure to
get things going:
gpio55 LCD RESET panel-dpi?
gpio56 LCD QVGA panel-dpi?
twl gpio7 LCD power panel-dpi
twl gpio15 LCD backlight gpio-backlight

We should set the GPIO polarity based on the OF_GPIO_ACTIVE_LOW like
gpio_backlight_probe_dt is doing.
Then do we really want to do the dev_err for each -EPROBE_DEFER here?

How about let's drop the backlight_gpio as discussed since it
can be handled with gpio-backlight?
Instead, let's add the panel specific reset_gpio as suggested by
Joachim. That seems common to some dpi using panels.
Then support for the other panel specific GPIOs can then be added
as a follow-up patch when we know how we want to handle them.
Oh, and this patch needs the related binding documentation too in
Documentation/devicetree/bindings.

Tony

Instead of doing it with the old gpio API, and checking the 'active'
flag everywhere, I think we can use the new gpiod API which handles the
polarity automatically.
I attached prototype patches (based on -rc2) for panel dpi using that
approach. It's a bit messier than I'd like, because for non-DT boot we
need to request the gpio using the old API, and then convert it to
gpio_desc. We can remove that code when all the boards use DT.
I've compiled tested this only, as I don't have DPI panels I could use.
I did try similar approach for TFP410, and it seemed to work fine.

Instead of doing it with the old gpio API, and checking the 'active'
flag everywhere, I think we can use the new gpiod API which handles the
polarity automatically.
I attached prototype patches (based on -rc2) for panel dpi using that
approach. It's a bit messier than I'd like, because for non-DT boot we
need to request the gpio using the old API, and then convert it to
gpio_desc. We can remove that code when all the boards use DT.
I've compiled tested this only, as I don't have DPI panels I could use.
I did try similar approach for TFP410, and it seemed to work fine.

Just FYI, you can use the gpiod API with non-DT platforms if you register GPIO
lookup entries in board code with gpiod_add_lookup_table().

Right, but as the board files are going away, I'd rather not touch them
at all if possible.

Got these working by updating my test patch to use enable-gpios instead
of gpios, and had to change from GPIO_ACTIVE_LOW to GPIO_ACTIVE_HIGH.
Are we now also breaking legacy booting by reversing the polarity?
In any case, looks like we have some duplicate panel code.. Turns
out most panel dpi users for omap3 board-*.c files are just
sharp-ls037v7dw01 panels but configured in QVGA mode. At least for
EVM and and LDP based on looking at the pictures and the configuration
pins (using the names kernel):
QVGA = lcd MO
reset = lcd RESB
...
Then the enable_gpio should be just a GPIO controlled 3.3V regulator
in most cases. I suggest we move them over to ls037v7dw01 and allow
configuring them both for VGA and QVGA depending on the orientation.
I guess you do have some device with ls037v7dw01 since you've been
patching it?

Tony

Got these working by updating my test patch to use enable-gpios instead
of gpios, and had to change from GPIO_ACTIVE_LOW to GPIO_ACTIVE_HIGH.
Are we now also breaking legacy booting by reversing the polarity?
In any case, looks like we have some duplicate panel code.. Turns
out most panel dpi users for omap3 board-*.c files are just
sharp-ls037v7dw01 panels but configured in QVGA mode. At least for
EVM and and LDP based on looking at the pictures and the configuration
pins (using the names kernel):
QVGA = lcd MO
reset = lcd RESB
...
Then the enable_gpio should be just a GPIO controlled 3.3V regulator
in most cases. I suggest we move them over to ls037v7dw01 and allow
configuring them both for VGA and QVGA depending on the orientation.
I guess you do have some device with ls037v7dw01 since you've been
patching it?

I don't think so. The GPIOs should be active-high by default, if I'm not
mistaken, so the polarities should be the same for legacy boot with or
without those patches. Of course, I don't have the boards so I have no
idea if the polarities have been correct even before.
debugfs/gpio shows the actual value of the gpio, so you could check from
there what it is.

Hmm, true, board-ldp.c's panel looks very much like sharp-ls037v7dw01.
Which EVM are you talking about?

Looking at the panel spec, it has the following pins:
RESB - reset
MO - VGA/QVGA
UD - vertical scanning direction
LR - horizontal scanning direction
INI - power on control
And it needs 3.3V power.
Are you saying that on some boards the gpio used for enable_gpio is
actually used to switch on a 3.3V regulator?

No, I don't have any boards with that panel.

Yes it seems so also based on the photos of the LCD panel. And 3430sdp
also seems to have something similar but it's upside down.

The LogicPD omap3 EVMs TMDSEVM3530 and TMDSEVM3730. The am335x EVM
has a different larger panel.

The 3.3V GPIO regulator is needed in addition to the configurable pins,
I guess some ls037v7dw01 panels only have a subset of the pins
controllable by GPIOs, and the GPIO regulator may be used instead of
the INI. But that's hard to know without schematics.

OK. I'll move my boards over to ls037v7dw01 and do a DT conversion
patch for it that just sets a standard gpios property for panel
ls037v7dw01. The gpios entry can have 0 entries in the middle
depending on wiring configuration and there should not be any need
to name each GPIO.
As far as I'm concerned, your panel-dpi patch is fine with me,
and we should not add more configuration to it for the ls037v7dw01
panels.

The LogicPD omap3 EVMs TMDSEVM3530 and TMDSEVM3730. The am335x EVM
has a different larger panel.

The 3.3V GPIO regulator is needed in addition to the configurable pins,
I guess some ls037v7dw01 panels only have a subset of the pins
controllable by GPIOs, and the GPIO regulator may be used instead of
the INI. But that's hard to know without schematics.

OK. I'll move my boards over to ls037v7dw01 and do a DT conversion
patch for it that just sets a standard gpios property for panel
ls037v7dw01. The gpios entry can have 0 entries in the middle
depending on wiring configuration and there should not be any need
to name each GPIO.
As far as I'm concerned, your panel-dpi patch is fine with me,
and we should not add more configuration to it for the ls037v7dw01
panels.

Tony
