The hope is that this method will be much faster and more reliable than bit banging for fetching EDIDs from buggy monitors or through switches, though we still preserve the bit banging as a fallback in case GMBUS fails. Based on an original patch by Jesse Barnes. Cc: Jesse Barnes Signed-off-by: Chris Wilson --- Reading git-diff-tree failed
