When using a 24-bit panel on a 8-bit serial bus, the pixel clock requested by the panel has to be multiplied by 3, since the subpixels are shifted sequentially.
The code (in ingenic_drm_encoder_atomic_check) already computed crtc_state->adjusted_mode->crtc_clock accordingly, but clk_set_rate() used crtc_state->adjusted_mode->clock instead.

Hi,
Can I have an ACK for this patch?
Then I can apply it to drm-misc-next-fixes.

Since you're committer it's expected that you go actively out to look for review or trade with someone else who has some patches that need a quick look. It will not happen automatically, this is on you.
Also generally after 2 weeks the patch is lost and you need to ping it. -Daniel

I maintain all drivers, platform code and DTS for Ingenic SoCs so I do my part, just not in this subsystem.
Also generally after 2 weeks the patch is lost and you need to ping it.
OK. Then I guess I'll just include this one in a future patchset.

Well you do have an ack now. I just meant to highlight that generally it doesn't happen automatically, and also that after 2 weeks generally a patchset wont get attention anymore. -Daniel
