[PATCH v3 0/2] MIPI DSI phy for rk3588

[Daniel Semkowicz]

Hello Heiko,

> This adds the phy driver need for DSI output on rk3588.
> 
> The phy itself is used for both DSI output and CSI input, though the
> CSI part for the whole chain needs a lot more work, so is left out for
> now and only the DSI part implemented.
> 
> This allows the rk3588 with its current VOP support to drive a DSI display
> using the DSI2 controller driver I'll submit in a next step.
> 
> Only generic phy interfaces are used, so the DSI part is pretty straight
> forward.
> 
> changes in v3:
> - add Krzysztof review tag to the binding
> - address Sebastian's review comments
>   - better error handling
>   - dropping empty function
>   - headers
>   - not using of_match_ptr - this should also make the
>     test-robot happier
> 
> changes in v2:
> - fix error in dt-binding example
> - drop unused frequency table
> - pull in some more recent improvements from the vendor-kernel
>   which includes a lot less magic values
> - already include the support for rk3576
> - use dev_err_probe

Thank you very much for these patches!

I tested this series on top of v6.12 with DSI/LVDS bridge
in the following configuration:

RK3588 Tiger SoM (dsi0) --> TC358775 DSI/LVDS bridge --> LVDS display

I did not observe any undesirable artifacts on the display.
Display blank/unblank works correctly.

Kind regards
