Nicholas Kazlauskas fbbd3f8f6b drm/amd/display: Add GPINT handler interface ... [Why] The General Purpose Interrupt is used on the DMCUB to pass lightweight commands via a register to the DMCUB. This is limited to 32-bit command and 32-bit response. This will be used for shutting down the firmware in a clean manner. [How] Add the command IDs and the data register to correctly format the commands. Add the interface functions to dmub_srv for sending and receiving the commands.
