From: Anthony Koo <Anthony.Koo@xxxxxxx>
- Add is_drr parameter to indicate DRR is enabled on
the panel to determine whether SubVP MCLK switch
logic should be enabled
- Add DRR manual trigger in FW (instead of driver)
because manual trigger programming triggers DRR
update pending and can block SubVP MCLK switches
from taking place
