This patchset addresses a couple of issues with the i915 gmbus implementation.
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
