[PATCH 2/5] drm: msm: a6xx: Add support for A618

[Sharat Masetty]

This patch adds support for enabling Graphics Bus Interface(GBIF)
used in multiple A6xx series chipets. Also makes changes to the
PDC/RSC sequencing specifically required for A618. This is needed
for proper interfacing with RPMH.

fwiw, this one we already landed, but in the future for things like
this, a Fixes tag is a good idea so that patches get backported to
appropriate stable branches.  In this case,

Fixes: 1707add81551 ("drm/msm/a6xx: Add a6xx gpu state")

Re: [PATCH 5/5] arm: dts: sc7180: Add A618 gpu dt blob

[Matthias Kaehlcke]

Hi Sharat,

on which tree is this patch based on? It does not apply against qcom/arm64-for-5.6-to-be-rebased.

In one of my repos which has a non-upstream Qualcomm tree as remote git can
make sense of the hashes in the index line, however the parent of your patch
looks quite different from the maintainer version.

Another thing that hints towards a custom tree:

> +			interconnects = <&gem_noc 35 &mc_virt 512>;

To my knowledge no patches have been posted to add the referenced interconnect
nodes for SC7180.

Please base your patches on the appropriate maintainer tree(s).

Thanks

Matthias
