[Why] Fix minor issues in BW Allocation Phase2. [How] - In set_usb4_req_bw_req(), link->dpia_bw_alloc_config.response_ready flag should be reset before writing DPCD REQUEST_BW. - Fix the granularity for value of 2 in get_bw_granularity(). - Removed bandwidth allocation support display fw boot option as the fw would read feature enable status from bios. - Clean up DPIA_EST_BW_CHANGED and DPIA_BW_REQ_SUCCESS cases in dpia_handle_bw_alloc_response(). - Removed allocate_usb4_bw and deallocate_usb4_bw. - Optimized loop in get_lowest_dpia_index(). - Updated link_dp_dpia_allocate_usb4_bandwidth_for_stream() and set_usb4_req_bw_req() to always issue request bw.

2024-01-03drm/amd/display: Don't allow FPO if no planesAlvin Lee
In DCN32/321 FPO uses per-pipe P-State force. If there is no plane, then then HUBP is power gated, in which case any programming in HUBP has no effect and the pipe is always asserting P-State allow. This is contrary to what we want to happen for FPO (FW should moderate the P-State assertion), so block FPO if there's no plane for the FPO pipe.

2023-12-19drm/amd/display: Only clear symclk otg flag for HDMIAlvin Lee
[Description] There is a corner case where the symclk otg flag is cleared when disabling the phantom pipe for subvp (because the phantom and main pipe share the same link). This is undesired because we need the maintain the correct symclk otg flag state for the main pipe. For now only clear the flag only for HDMI signal type, since it's only set for HDMI signal type (phantom is virtual). The ideal solution is to not clear it if the stream is phantom but currently there's a bug that doesn't allow us to do this. Once this issue is fixed the proper fix can be implemented.

2023-12-19drm/amd/display: Refactor DMCUB enter/exit idle interfaceNicholas Kazlauskas
[Why] We can hang in place trying to send commands when the DMCUB isn't powered on. [How] We need to exit out of the idle state prior to sending a command, but the process that performs the exit also invokes a command itself. Fixing this issue involves the following: 1. Using a software state to track whether or not we need to start the process to exit idle or notify idle. It's possible for the hardware to have exited an idle state without driver knowledge, but entering one is always restricted to a driver allow - which makes the SW state vs HW state mismatch issue purely one of optimization, which should seldomly be hit, if at all. 2. Refactor any instances of exit/notify idle to use a single wrapper that maintains this SW state. This works simialr to dc_allow_idle_optimizations, but works at the DMCUB level and makes sure the state is marked prior to any notify/exit idle so we don't enter an infinite loop. 3. Make sure we exit out of idle prior to sending any commands or waiting for DMCUB idle. This patch takes care of 1/2. A future patch will take care of wrapping DMCUB command submission with calls to this new interface.

2023-12-19drm/amd/display: Unify optimize_required flags and VRR adjustmentsAric Cyr
[why] There is only a single call to dc_post_update_surfaces_to_stream so there is no need to have two flags to control it. Unifying this to a single flag allows dc_stream_adjust_vmin_vmax to skip actual programming when there is no change required. [how] Remove wm_optimze_required flag and set only optimize_required in its place. Then in dc_stream_adjust_vmin_vmax, check that the stream timing range matches the requested one and skip programming if they are equal.
