[PATCH 4/4] drm/msm/dsi: Add phy configuration for MSM8937

[Barnabás Czémán]

From: Daniil Titov <daniilt971@gmail.com>

Add phy configuration for 28nm dsi phy found on MSM8937 SoC. Only
difference from existing msm8916 configuration is number of phy
and io_start addresses.

This is an automated instruction, just in case, because many review tags
are being ignored. If you know the process, you can skip it (please do
not feel offended by me posting it here - no bad intentions intended).
If you do not know the process, here is a short explanation:

Please add Acked-by/Reviewed-by/Tested-by tags when posting new
versions, under or above your Signed-off-by tag. Tag is "received", when
provided in a message replied to you on the mailing list. Tools like b4
can help here. However, there's no need to repost patches *only* to add
the tags. The upstream maintainer will do that for tags received on the
version they apply.

Is this would be qcom,mdss-has-source-split in downstream, because if
it is i think it is a mistake and it is wrong at msm8953 also.
