[PATCH v4 0/9] move Rockchip ISP bindings out of staging / add ISP DT nodes for RK3399

[PATCH v4 0/9] move Rockchip ISP bindings out of staging / add ISP DT nodes for RK3399

[Helen Koike]

Move the bindings out of drivers/staging and place them in
Documentation/devicetree/bindings instead.

Also, add DT nodes for RK3399 and verify with make ARCH=arm64 dtbs_check
and make ARCH=arm64 dt_binding_check.

Tested by verifying images streamed from Scarlet Chromebook

Changes in v4:
- simplify clocks with "isp", "aclk" and "hclk" as suggested by
Robin Murphy on https://patchwork.kernel.org/patch/11475007/

Changes in v3:
- dropped accepted patches
- cleanup clocks
- fix "no reg" error in dt-bindings parent@0 example
- add linux-rockchip list in MAINTAINERS and reorder items
- add Scarlet sensors dt nodes to the series

Changes in v2:
Add patches modifying bindings, as sugested by Johan Jonker in v1,
before moving them out of staging.

This will give a warning now as the default cell sizes are 1.

Just drop the unit address rather than adding all this.

This will give a warning now as the default cell sizes are 1.

[PATCH v4 3/9] media: staging: dt-bindings: rkisp1: re-order properties

[Helen Koike]

On top: compatible, reg and interrupts.
Then alphabetical order, then properties starting with '#'.

[PATCH v4 5/9] media: staging: rkisp1: remove unecessary clocks

[Helen Koike]

aclk_isp_wrap is a child of aclk_isp, and hclk_isp_wrap is a child of
hclk_isp, thus we can remove parents from the list.

Also, for the isp0, we only need the ISP clock, ACLK and HCLK.
In the future we'll need a pixel clock for RK3288 and RK3399, and a JPEG
clock for RK3288.

So with the goal to cleanup the dt-bindings and remove it from staging,
simplify clock names to isp, aclk and hclk.

For reference, this is the isp clock topology on RK3399:

 xin24m
    pll_npll
       npll
          clk_isp1
          clk_isp0
    pll_cpll
       cpll
          aclk_isp1
             aclk_isp1_noc
             hclk_isp1
                aclk_isp1_wrapper
                hclk_isp1_noc
          aclk_isp0
             hclk_isp1_wrapper
             aclk_isp0_wrapper
             aclk_isp0_noc
             hclk_isp0
                hclk_isp0_wrapper
                hclk_isp0_noc
 pclkin_isp1_wrapper

But it looks like it is the wrap clocks you are removing.

This is the correct way to describe multiple clocks.

Now the 4th and 5th clock are undefined.

This should not be more than the number of entries in 'items'.

This is the correct way to describe multiple clocks.

Now the 4th and 5th clock are undefined.

Hi Rob,

Thanks for your review.

From this binding yes, but the idea is to add in the dt wherever clock
responsible for the full ACLK path for instance.
In the example below, clock aclk_isp is ACLK_ISP0_WRAPPER.
Does this make sense?

The idea was to prepare for rk3288 and rk3399 isp1, as suggested here https://patchwork.kernel.org/patch/11475007/#23462085

Or should we do:

clocks:
  oneOf:
    # rk3288 clocks
    - items:
      - description: ISP clock
      - description: ISP AXI clock
      - description: ISP AHB clock
      - description: ISP Pixel clock
      - description: ISP JPEG source clock
    # rk3399 isp0 clocks
    - items:
      - description: ISP clock
      - description: ISP AXI clock
      - description: ISP AHB clock
    # rk3399 isp1 clocks
    - items:
      - description: ISP clock
      - description: ISP AXI clock
      - description: ISP AHB clock
      - description: ISP Pixel clock

?

If we follow what I wrote above, should we have:

    clock-names:
      oneOf:
        # rk3288 clocks
        - items:
          - const: clk_isp
          - const: aclk_isp
          - const: hclk_isp
          - const: pclk_isp_in
          - const: sclk_isp_jpe
        # rk3399 isp0 clocks
        - items:
          - const: clk_isp
          - const: aclk_isp
          - const: hclk_isp
        # rk3399 isp1 clocks
        - items:
          - const: clk_isp
          - const: aclk_isp
          - const: hclk_isp
          - const: pclk_isp

?

From this binding yes, but the idea is to add in the dt wherever clock
responsible for the full ACLK path for instance.
In the example below, clock aclk_isp is ACLK_ISP0_WRAPPER.
Does this make sense?

The idea was to prepare for rk3288 and rk3399 isp1, as suggested here https://patchwork.kernel.org/patch/11475007/#23462085

Or should we do:

clocks:
  oneOf:
    # rk3288 clocks
    - items:
      - description: ISP clock
      - description: ISP AXI clock
      - description: ISP AHB clock
      - description: ISP Pixel clock
      - description: ISP JPEG source clock
    # rk3399 isp0 clocks
    - items:
      - description: ISP clock
      - description: ISP AXI clock
      - description: ISP AHB clock
    # rk3399 isp1 clocks
    - items:
      - description: ISP clock
      - description: ISP AXI clock
      - description: ISP AHB clock
      - description: ISP Pixel clock

?

If we follow what I wrote above, should we have:

    clock-names:
      oneOf:
        # rk3288 clocks
        - items:
          - const: clk_isp
          - const: aclk_isp
          - const: hclk_isp
          - const: pclk_isp_in
          - const: sclk_isp_jpe
        # rk3399 isp0 clocks
        - items:
          - const: clk_isp
          - const: aclk_isp
          - const: hclk_isp
        # rk3399 isp1 clocks
        - items:
          - const: clk_isp
          - const: aclk_isp
          - const: hclk_isp
          - const: pclk_isp

?

The main section should have this and 'minItems: 3'. IOW, it's a
superset of what's valid. Then you can restrict specific compatibles
further with an if/then schema. For rk3288, you need one with
'minItems: 5'.

And this would be an if/then schema based on the compatible string and
defining 'maxItems: 3'.

And an if/then with { minItems: 4, maxItems: 4 }. Or really since
these are just different instances, just combine them into 1
conditional allowing 3 or 4 clocks.

There are lots of examples to follow in the tree.

The main section should have this and 'minItems: 3'. IOW, it's a
superset of what's valid. Then you can restrict specific compatibles
further with an if/then schema. For rk3288, you need one with
'minItems: 5'.

>     - items:
>       - description: ISP clock
>       - description: ISP AXI clock
>       - description: ISP AHB clock

And this would be an if/then schema based on the compatible string and
defining 'maxItems: 3'.

And an if/then with { minItems: 4, maxItems: 4 }. Or really since
these are just different instances, just combine them into 1
conditional allowing 3 or 4 clocks.

There are lots of examples to follow in the tree.
