[PATCH v3 0/4] media: rockchip: rga: PX30 support and YUV2YUV fix

[Paul Kocialkowski]

Hi,

This series adds support for the Rockchip PX30 SoC in the V4L2 M2M RGA driver.
It also contains a fix for the YUV2YUV case that was not properly handled.

Changes since v2:
- Used RK3288 compatible in PX30 dts, removed PX30 compatible from driver;
- Added cleanup patch with format macros;
- Added comment about CSC mode fix.

Changes since v1:
- Rebased on media tree master (changed dt binding to yaml);
- Removed spurious line removal.

Cheers,

Paul

Are you sure about this? The rk3228 above does it as I did it and other examples
like allwinner,sun4i-a10-csi.yaml appear to be doing the same too.

The case with rockchip,rk3288-rga alone already seems covered.

Paul

Re: [PATCH v3 1/4] dt-bindings: rockchip-rga: Add PX30 compatible

[Johan Jonker]

Hi Paul,

With help of enum each additional compatibility string with fall back
'rockchip,rk3288-rga' adds only 1 extra line instead of 3.

See my and Heiko's response at the review of 'rockchip-saradc.yaml'.

The use of enum starts from 2 or more identical fall back strings.
'allwinner,sun4i-a10-csi.yaml' has 2 different fall back strings.

properties:
  compatible:
    oneOf:
      - const: allwinner,sun4i-a10-csi1
      - const: allwinner,sun7i-a20-csi0
      - items:
        - const: allwinner,sun7i-a20-csi1
        - const: allwinner,sun4i-a10-csi1
      - items:
        - const: allwinner,sun8i-r40-csi0
        - const: allwinner,sun7i-a20-csi0

The use of enum starts from 2 or more identical fall back strings.
'allwinner,sun4i-a10-csi.yaml' has 2 different fall back strings.

properties:
  compatible:
    oneOf:
      - const: allwinner,sun4i-a10-csi1
      - const: allwinner,sun7i-a20-csi0
      - items:
        - const: allwinner,sun7i-a20-csi1
        - const: allwinner,sun4i-a10-csi1
      - items:
        - const: allwinner,sun8i-r40-csi0
        - const: allwinner,sun7i-a20-csi0

What's the rationale behind this (besides alphabetic sorting, which I don't
believe is a rule for dt properties)? Some nodes above in the file have it in
the same order that I do, and I like to see clocks followed by resets.

My short list.
There is no hard rule... It mostly depend on Heiko...

For nodes:
If exists on top: model, compatible and chosen.
Sort things without reg alphabetical first,
then sort the rest by reg address.

Inside nodes:
If exists on top: compatible, reg and interrupts.
In alphabetical order the required properties.
Then in alphabetical order the other properties.
And as last things that start with '#' in alphabetical order.
Add status below all other properties for soc internal components with
any board-specifics.
Keep an empty line between properties and nodes.

Exceptions:
Sort pinctrl-0 above pinctrl-names, so it stays in line with clock-names
and dma-names.
Sort simple-audio-card,name above other simple-audio-card properties.
Sort regulator-name above other regulator properties.
Sort regulator-min-microvolt above regulator-max-microvolt.

My short list.
There is no hard rule... It mostly depend on Heiko...

For nodes:
If exists on top: model, compatible and chosen.
Sort things without reg alphabetical first,
then sort the rest by reg address.

Inside nodes:
If exists on top: compatible, reg and interrupts.
In alphabetical order the required properties.
Then in alphabetical order the other properties.
And as last things that start with '#' in alphabetical order.
Add status below all other properties for soc internal components with
any board-specifics.

For the record, if needed I do any re-sorting myself normally, so there is
no need to respin patches just because nodes are sorted differently.

But yes, since the early Chromebook project in 2014 we agreed on
doing in Rockchip dts files:

----
compatible
reg
interrupts
[alphabetical]
status [if needed]
----

This works most of the time, but sometimes gets missed but is not _that_
big a deal if that happens ;-) .

[PATCH v3 3/4] media: rockchip: rga: Introduce color fmt macros and refactor CSC mode logic

[Paul Kocialkowski]

This introduces two macros: RGA_COLOR_FMT_IS_YUV and RGA_COLOR_FMT_IS_RGB
which allow quick checking of the colorspace familily of a RGA color format.

These macros are then used to refactor the logic for CSC mode selection.
The two nested tests for input colorspace are simplified into a single one,
with a logical and, making the whole more readable.

[PATCH v3 4/4] media: rockchip: rga: Only set output CSC mode for RGB input

[Paul Kocialkowski]

Setting the output CSC mode is required for a YUV output, but must not
be set when the input is also YUV. Doing this (as tested with a YUV420P
to YUV420P conversion) results in wrong colors.

Adapt the logic to only set the output CSC mode when the output is YUV and
the input is RGB. Also add a comment to clarify the rationale.
