[Intel-gfx] [PATCH 3/3] drm/i915/tgl+: Sanitize DKL PHY register definitions

Imre Deak imre.deak at intel.com
Tue Oct 18 17:20:42 UTC 2022


Not all Dekel PHY registers have a lane instance, so having to specify
this when using them is awkward. It makes more sense to define each PHY
register with its full internal PHY offset where bits 15:12 is the lane
for lane-instanced PHY registers and just a register bank index for other
PHY registers. This way lane-instanced registers can be referred to with
the (tc_port, lane) parameters, while other registers just with a tc_port
parameter.

An additional benefit of this change is to prevent passing a Dekel
register to a generic MMIO access function or vice versa.
