[Intel-gfx] [PATCH v3 1/2] drm/i915/gmbus: Increase the Bytes per Rd/Wr Op

2018-04-17 Thread Ramalingam C
From Gen9 onwards Bspec says HW supports Max Bytes per single RD/WR op is 511Bytes instead of previous 256Bytes used in SW. This change allows the max bytes per op upto 511Bytes from Gen9 onwards. v2: No Change. v3: Inline function for max_xfer_size and renaming of the macro.[Jani] Cc: Jani
