From f9c10a9b96a31b4a82a4fa807400c04f00284068 Mon Sep 17 00:00:00 2001 From: Keith Packard Date: Sat, 30 May 2009 12:16:25 -0700 Subject: drm/i915: Change I2C api to pass around i2c_adapters The existing API passed around intel_i2c_chan pointers, which are dependent on the i2c bit-banging algo. This precluded the driver from using outputs which use a different algo. Switching to the more general i2c_adpater allows the driver to support non bit-banging DDC. This also required moving the slave address into the output private structures.
