drm/amd/display: add event type check before restart the authentication

2020-01-07T17:13:42+00:00

[Why] Some combined docks will always trigger CP_IRQ but there's nothing the driver needs to take care of, but the CP_IRQ breaks the original hdcp state and triggers the driver to restart the authentication.

drm/amd/display: Add delay after h' watchdog timeout event

2020-01-07T17:13:35+00:00

[WHY] Some monitors trigger HDCP2.x timeout after reinitializing (e.g. toggling HDR) by taking longer than expected to return h' (h prime) Previously the 200ms watchdog timer retry count would hit MAX_NUM_OF_ATTEMPTS (4), causing fallback to HDCP1.x [HOW] Adding a 1s delay after an h' watchdog timeout provides enough time for affected monitors to return h' in time without hitting MAX_NUM_OF_ATTEMPTS Signed-off-by: Michael Strauss Reviewed-by: Wenjing Liu Acked-by: Harry Wentland Signed-off-by: Alex Deucher

drm/amdgpu/display: use msleep rather than udelay for HDCP

2019-12-18T23:04:13+00:00

ARM has a 2000us limit for udelay. Switch to msleep. This code executes in a worker thread so shouldn't be an atomic context.
