[Intel-gfx] [PATCH 10/13] drm/i915/mtl: Power up TCSS

2023-04-20 Thread Mika Kahola
Add register writes to enable powering up Type-C subsystem i.e. TCSS. For MeteorLake we need to request TCSS to power up and check the TCSS power state after 500 us. In addition, for PICA we need to set/clear the Type-C PHY ownnership bit when Type-C device is connected/disconnected.
