Subject: [PATCH 0/5] drm/msm/dp: Allow variation in register regions
Date: Wed, 21 Jul 2021 19:42:22 -0700	[thread overview]
Message-ID: <20210722024227.3313096-1-bjorn.andersson@linaro.org> (raw)

It turns out that sc8180x (among others) doesn't have the same internal layout
of the 4 subblocks. This series therefor modifies the binding to require all
four regions to be described individually and then extends the driver to read
these four regions. The driver will fall back to read the old single-reg format
and apply the original offsets and sizes.

Bjorn Andersson (5):
  dt-bindings: msm/dp: Change reg definition
  drm/msm/dp: Use devres for ioremap()
  drm/msm/dp: Refactor ioremap wrapper
  drm/msm/dp: Store each subblock in the io region
  drm/msm/dp: Allow sub-regions to be specified in DT
