drm/radeon/kms: fix up gpio i2c mask bits for r4xx 2011-12-09T16:52:23+00:00 Alex Deucher alexander.deucher@amd.com 2011-11-14T19:32:01+00:00 ff17063daf7bcf76ee1b1cc59e20ae725affc555 commit 6c47e5c23aa2a7c54ad7ac13af4bd56cd9e703bf upstream. Fixes i2c test failures when i2c_algo_bit.bit_test=1. The hw doesn't actually require a mask, so just set it to the default mask bits for r1xx-r4xx radeon ddc.

Allow the user to override whether MSIs are enabled or not on supported ASICs. MSIs are disabled by default on IGP chips as they tend not to work. However certain IGP chips only seem to work with MSIs enabled. I suspect this is a chipset or bios issue, but I'm not sure what the proper fix is.
