I think the patch order should be reversed. Each commit should work. Can be applied in a different order without resending. There's maybe a bit too much happening in patch 2 for my liking, but *shrug*.

Currently, we may bump into pll mismatch errors during the state verification stage. This happens when we try to use fastset instead of full modeset. Hence, we would need to add a check for pipe configuration to ensure that the sw and the hw configuration will match. In case of hw and sw mismatch, we would need to disable fastset and use full modeset instead. However, first we need to revert the patch that disables fastset for C10. v2: Fix C10 error on PLL comparison (BAT) Use memcmp instead of fixed loops for pll config comparison (Jani) Clean up and use intel_cx0pll_dump_hw_state() to dump pll information (Jani) Signed-off-by: Mika Kahola <mika.kahola@intel.com> Mika Kahola (2): drm/i915/display: Revert "drm/i915/display: Skip C10 state verification in case of fastset" drm/i915/display: Add compare config for MTL+ platforms drivers/gpu/drm/i915/display/intel_cx0_phy.c | 80 ++++++++++++++++--- drivers/gpu/drm/i915/display/intel_cx0_phy.h | 8 +- drivers/gpu/drm/i915/display/intel_display.c | 33 ++++++++ drivers/gpu/drm/i915/display/intel_dpll_mgr.h | 1 + 4 files changed, 109 insertions(+), 13 deletions(-)
