Hi Sean,
Could you give some comments for this patch?
Thanks

We will ignored PSR setting if panel not support it. So, in this case, we should
return from analogix_dp_enable/disable_psr() without any error code.
Let's retrun 0 instead of -EINVAL when panel not support PSR in
analogix_dp_enable/disable_psr().

There's a race between when bridge_disable and when vop_crtc_disable are called.
If the flush timer triggers a new psr work between these, we will operate eDP
