LinuxLists.cc - [PATCH v5 7/7] drm/msm/dp: Add sc8180x DP controllers

2021-10-18 03:39:08

Subject: [PATCH v5 7/7] drm/msm/dp: Add sc8180x DP controllers

The sc8180x has 2 DP and 1 eDP controllers, add support for these to the
DP driver.

Link: https://lore.kernel.org/linux-arm-msm/[email protected]/
Signed-off-by: Bjorn Andersson <[email protected]>

Changes since v4:
- Use the MSM_DP_CONTROLLER_n enums
- const the msm_dp_desc array

No, I didn't intend for this Link to go upstream, just forgot to clean
it out as I was sending out the patches.

@Rob, @Dmitry, can you drop this as you apply the patch, or would you
prefer a resend?

Thanks,

It seems that SC8180x DPU support was never merged (because of
hw_interrupt rework, because of hw_catalog TODOs and FIXMEs). Could you
please post new iteration of that patchset, squashing this one into it?
