[PATCH 0/7 v6] fix gmbus writes and related issues

From: Daniel Kurtz
Date: Wed Mar 28 2012 - 14:28:09 EST

This patchset addresses a couple of issues with the i915 gmbus

v6 is a rebased and trimmed version of the patchset,
since the first few patches have already been merged onto drm-intel-next-queued.
* Cleans up INDEX cycle implementation
* Only remove POSTING_READ() when it immediately precedes another I915_READ().

Daniel Kurtz (7):
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
