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.

At first duplicate sdvo fixed mode for adjustment, then according to fixed mode line valid all modes, at last adjust input mode to fit our requirement.
