From 93e2323b5c85a2b7ac4260d720de26ca5d5ad796 Mon Sep 17 00:00:00 2001 From: Matt Roper Date: Mon, 4 May 2020 15:52:13 -0700 Subject: [PATCH] drm/i915/rkl: Add power well support RKL power wells are similar to TGL power wells, but have some important differences: * PG1 now has pipe A's VDSC (rather than sticking it in PG2) * PG2 no longer exists * DDI-C (aka TC-1) moves from PG1 -> PG3 * PG5 no longer exists due to the lack of a fourth pipe Also note that what we refer to as 'DDI-C' and 'DDI-D' need to actually be programmed as TC-1 and TC-2 even though this platform doesn't have TC outputs.
