drm/amd/display: read invalid ddc pin status cause engine busy

2022-12-06T15:16:24+00:00

[Why] There is no DDC_6 pin on new asic cause the mapping table is incorrect. When app try to access DDC_VGA port, driver read an invalid ddc pin status and report engine busy. [How] Add dummy DDC_6 pin to align gpio structure. Reviewed-by: Alvin Lee Acked-by: Stylon Wang Signed-off-by: Paul Hsieh Tested-by: Daniel Wheeler Signed-off-by: Alex Deucher
