[Why] get_channel_status() can return 0 in returned_bytes, and report a successful operation result. This is because it prunes the first status byte out. This was preventing read_channel_reply() from being called (due to the faulty condition), and consequently preventing the AUX reply status from being set. [How] Fix the conditional so that it accounts for when get_channel_status() returns 0 bytes read. [Fixes] Fixes possible edid read failures during S3 resume, where we are now relying on DRM's DP AUX handling.

[Why] Some monitors mark 4K@60 capable HDMI port only have 300MHz TMDS maximum, but the edid includes 4K@60 mode in cea extension block. [How] To enable 4K@60, need to limit BW by allowing YCbCr420 ONLY mode. Add YCbCr420 only support for monitors that do not fully support HDMI2.0, e.g., ASUS PA328. The YCbCr420 only support applies to DCN, DCE112 or higher. Signed-off-by:

bug fix: phy test PLTAT is special 80bit test pattern. The 80bit data should be hard coded within driver so that user does not need input the deata. previous driver does not have hard coded 80 bits pattern data for PLTPAT. Other than this PLTPAT, user has to input 80 bits pattern data. In case user input less than 10 bytes data, un-input data byte will be filled by 0x00. Signed-off-by:

Currently we still go through DC code that does error checking, retries, etc. There's no need for that since DRM already does that for us. This simplifies the code a bit and makes it easier to debug. This also ensures we correctly tell DRM how many bytes have actually been read, as we should. This allows DRM to correctly read the EDID on the Chamelium DP port. Signed-off-by:

DRM's DP helpers take care of dealing with the error code for us. In order not to step on each other's toes we'll need to be able to simply read auch channel replies without further logic based on return values. Signed-off-by:

Access to GPIO needs to be serialized. Aux transactions are already serialized in DRM but we also need to serialize access to the GPIO pin for purposes of DP dongle detection. Call is_dp_sink_present through DM so we can lock correctly. This follows the same pattern used for DPCD transactions. Signed-off-by:
