drm/i915/display: Allow display PHYs to reset power state
The dedicated display PHYs reset to a power state that blocks S0ix,
increasing idle system power. After a system reset (cold boot,
S3/4/5, warm reset) if a dedicated PHY is not being brought up
shortly, use these steps to move the PHY to the lowest power state
to save power.
1. Follow the PLL Enable Sequence, using any valid frequency such
as DP 1.62 GHz. This brings lanes out of reset and enables the
PLL to allow powerdown to be moved to the Disable state.
2. Follow PLL Disable Sequence. This moves powerdown to the Disable
state and disables the PLL.
v2: Rename WA function to more descriptive (Jani)
For PTL, only port A needs this wa
Add helpers to check presence of C10 phy and pll enabling (Imre)
v3: Rename wa function (Imre)
Check return value of C10 pll tables readout (Imre)
Use PLL request to check pll enabling (Imre)
v4: Move intel_cx0_pll_is_enabled() right after
intel_cx0_pll_disable() (Imre)
Add drm_WARN_ON() if C10 state cannot be calculated from
the tables (Imre)
