Subject: [PATCH v3 0/5] drm/msm/dp: Allow variation in register regions

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
