Re: [PATCH v2] drm/rockchip: vop2: Scale the AXI clock to the bandwidth the mode needs

[Igor Paunovic <royalnet026@gmail.com>]

Hi Owen,

Thank you - and thank you for bringing this to the list. A fanless
RK3588J chassis at 60C ambient running dual HDMI plus DP is a far
stronger argument for scaling this clock than my bench ever was, and
the +3-5C junction delta at 750 MHz is exactly the number the
power/thermal side of this discussion was missing.

On your question - both, sequenced, because they answer different
questions:

- The BSP 6.1 48h soak first. That is your production reality and it
  needs no bring-up; what it buys is the real-world deployment
  evidence, and with your permission I will cite it in the v3 cover
  letter alongside the multi-CRTC tearing observation.

- The mainline clean-room run when your DTS bring-up is ready. v3 will
  be against drm-misc-next, and that run is the one I would attach
  your Tested-by to, so the tag attests the tree the patch actually
  targets. No rush on this one - if it lands during the v3 review
  cycle rather than before it, that is still perfect timing.

I will CC you on v3. It will state the FRL/ACLK relationship
explicitly (on my board the HDMI FRL path holds the clock at 750 MHz
independently, which is why the DP path was the one that exposed the
scaling gap), and it will pick one direction for commit_setup vs
commit_tail and defend it in the cover letter - the question to the
maintainers about a rockchip-wide hook pair is still open, and v3
cannot wait on it forever.

Regards,
Igor
