Subject: [PATCH v3 0/5] drm/msm/dp: Allow variation in register regions
Date: Fri, 1 Oct 2021 10:43:55 -0700 [thread overview]
Message-ID: <20211001174400.981707-1-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
