Adds support for clock requests for the various parts of the DCN3.1 IP and the interfaces and definitions for sending messages to SMU/PMFW. Includes new support for z9/10, detecting SMU timeout and p-state support enablement. Acked-by: Huang Rui Signed-off-by: Nicholas Kazlauskas Signed-off-by: Alex Deucher

drm/amd/display: Support for DMUB AUX

2021-05-10T22:06:44+00:00

[WHY] To process AUX transactions with DMUB using inbox1 and outbox1 mail boxes. [How] 1) Added inbox1 command DMUB_CMD__DP_AUX_ACCESS to issue AUX commands to DMUB in dc_process_dmub_aux_transfer_async(). DMUB processes AUX cmd with DCN and sends reply back in an outbox1 message triggering an outbox1 interrupt to driver. 2) In existing driver implementation, AUX commands are processed synchronously by configuring DCN reg. But in DMUB AUX, driver sends an inbox1 message and waits for a conditional variable (CV) which will be signaled by outbox1 ISR. 3) DM will retrieve Outbox1 message and send back reply to upper layer and complete the AUX command Signed-off-by: Jude Shih Reviewed-by: Hanghong Ma Reviewed-by: Nicholas Kazlauskas Acked-by: Wayne Lin Tested-by: Daniel Wheeler Signed-off-by: Alex Deucher
