[PATCH 0/4] move Rockchip ISP bindings out of staging / add ISP DT nodes for RK3399

[PATCH 0/4] 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

Tested by verifying images streamed from RockPi 4 board with imx219
module.

Hi Helen,

I was wondering if we couldn't also move the phy driver out of staging.

Thanks,

Maybe a little sort? But keep rest as it is. Also in example.

		iommus = <&isp0_mmu>;
		phys = <&mipi_dphy_rx0>;
		phy-names = "dphy";
		power-domains = <&power RK3399_PD_ISP0>;

Move reg above #address-cells. Change that in example as well.

				reg = <0>;
				#address-cells = <1>;
				#size-cells = <0>;

Are you proposing only to move power-domains after phy? And keep the rest?
What is the main logic?

There is no hard rule... It mostly depend on Heiko...

For nodes:
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.

The use of '@0' makes "#address-cells" and "#size-cells" also a requirement.

- "#address-cells"
- "#size-cells"

Incomplete example.
From i2c-rk3x.yaml:

Nothing required here?

The use of '@0' makes "#address-cells" and "#size-cells" also a requirement.

- "#address-cells"
- "#size-cells"

How about 'reg'?

Incomplete example.
From i2c-rk3x.yaml:

  - compatible

I was thinking that if there is no endpoint, then nothing is required.
But if there is, then #address-cells, #size-cells and reg are. I guess
I can just add them as required.

I'll add it in the patchseries.

The idea was to exemplify how to connect to the sensor nodes below.
But I don't see a problem adding a complete i2c example, I'll add it.

I'll add it in the patchseries.

The idea was to exemplify how to connect to the sensor nodes below.
But I don't see a problem adding a complete i2c example, I'll add it.

[PATCH 3/4] arm64: dts: rockchip: add rx0 mipi-phy for rk3399

[Helen Koike]

From: Shunqian Zheng <zhengsq@rock-chips.com>

Designware MIPI D-PHY, used for ISP0 in rk3399.

Verified with:
make ARCH=arm64 dtbs_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/phy/rockchip-mipi-dphy-rx0.yaml

Signed-off-by: Shunqian Zheng <zhengsq@rock-chips.com>
Signed-off-by: Jacob Chen <jacob2.chen@rock-chips.com>
Signed-off-by: Helen Koike <helen.koike@collabora.com>

---

This patchset came from the original ISP series from Rockchip:

    https://patchwork.kernel.org/patch/10267409/

The only difference is:
- add phy-cells
- update compatible to "rockchip,rk3399-mipi-dphy-rx0"
- commit message

Similar to main nodes ... so things without reg alphabetical,
the rest by reg address

.@..

or

with reg values first:

.@..

For the record, pinctrl at the bottom of a soc.dtsi is ok.
