Subject: [PATCH 0/8 v7] fix gmbus writes and related issues
Date: Fri, 30 Mar 2012 19:46:35 +0800 [thread overview]
Message-ID: <1333108003-6341-1-git-send-email-djkurtz@chromium.org> (raw)
This patchset addresses a couple of issues with the i915 gmbus
implementation.
v7 adds a final patch to switch to using DRM_ERROR for reporting timeouts.
Daniel Kurtz (8):
drm/i915/intel_i2c: handle zero-length writes
drm/i915/intel_i2c: use double-buffered writes
drm/i915/intel_i2c: always wait for IDLE before clearing NAK
drm/i915/intel_i2c: use WAIT cycle, not STOP
drm/i915/intel_i2c: use INDEX cycles for i2c read transactions
drm/i915/intel_i2c: reuse GMBUS2 value read in polling loop
drm/i915/intel_i2c: remove POSTING_READ() from gmbus transfers
drm/i915/intel_i2c: use DRM_ERROR on timeouts
