[PATCH v3 02/15] dt-bindings: display: rockchip: analogix-dp: Add support for RK3588
Posted by Damon Ding 12 months ago
Compared with RK3288/RK3399, the HBR2 link rate support is the main
improvement of RK3588 eDP TX controller, and there are also two
independent eDP display interfaces on RK3588 Soc.

Acked-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org>
Signed-off-by: Damon Ding <damon.ding@rock-chips.com>

Changes in v2:
- Add the main defferences of the RK3588 eDP and the previous versions
  in commit message

Changes in v3:
- expand the property clock-names, resets and reset-names

Drop, patch was very different.

Adding new properties invalidates reviews. The patch is entirely, really
significantly different so keeping the review is not acceptable.

No, this cannot be flexible for existing variants.

No, you must list the items.

I don't understand what happened here but all this is NAK. Why suddenly
existing variants became different/changed? Nothing in commit msg
explains this.

Best regards,

I will drop the 'spdif' because the audio feature has not been added to 
the analogix-dp driver in this patch series.

The newly added 'apb' reset is to ensure the APB bus of eDP controller 
works well on the RK3588 SoC. I will mention it in commit message in the 
next version.

The fixed patch will be like:

And I will add the APB reset operation in Rockchip analogix-dp driver, 
which was forgotten in the [PATCH v3 03/15].
