* drm/radeon/kms/dce3+: add support for hw i2c using atomAlex Deucher2012-02-031-0/+139
Starting with DCE3 hardware, atom contains a general purpose ProcessI2cChannelTransaction similar to ProcessAuxChannelTransaction. Add an implementation using the atom tables for DCE3+ hardware. This should be a little less CPU intensive than bit banging and may work better in certain cases. Enable it by setting the radeon hw_i2c module parameter to 1. E.g., radeon.hw_i2c=1 on the kernel command line in grub. Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
