Subject: drm/i915/vlv: add early DPIO init v3
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=f42bb70d4ff976b134fcbfb50301a87e7523f042;p=openwrt%2Fstaging%2Fblogic.git

drm/i915/vlv: add early DPIO init v3

Just add an early init since we may need to access DPIO regs early on.
The init call in modeset_init_hw is also needed for the resume case,
when we need to reset DPIO to keep things happy.

v2: split reset and reg init
v3: split patches (Daniel)
