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:

User could unplug DP display from DP connected and plug scope to check test pattern PHY SI. If there is need unplug scope and plug DP display back, do steps below: echo 0 > phy_test_pattern unplug scope plug DP display. "echo 0 > phy_test_pattern" will re-enable HPD pin again so that video sw driver could detect "unplug scope" and "plug DP display" 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:

This reverts commit cc195141. This commit was problematic on other OSes. The real solution is to leave all the error checking to DRM and don't do it in DC, which is addressed by "Return aux replies directly to DRM" later in this patchset. v2: Add reason for revert. Signed-off-by:
