[Why] If bandwidth allocation feature is enabled, connection manager wont limit the dp tunnel bandwidth. So, need to do display mode validation for streams on dpia links to avoid oversubscription of dp tunnel bandwidth. [How] - To read non reduced link rate and lane count and update reported link capability. - To calculate the bandwidth required for streams of dpia links per host router and validate against the allocated bandwidth for the host router.

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. Tested-by:

[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. Reviewed-by:

[Why] We can hang in place trying to send commands when the DMCUB isn't powered on. [How] For functions that execute within a DC context or DC lock we can wrap the direct calls to dm_execute_dmub_cmd/list with code that exits idle power optimizations and reallows once we're done with the command submission on success. For DM direct submissions the DM will need to manage the enter/exit sequencing manually. We cannot invoke a DMCUB command directly within the DM execution helper or we can deadlock.

[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.
