Upstream Intel DRM developers have fixed this issue in commit 062499cc4813 (drm/i915/mtl+: Enable PPS before PLL), which addresses freedesktop work items #16098 and #16064.
The patch resolves the C10 PLL state mismatch (c10pll_hw_state / verify_crtc_state) during resume by ensuring the Panel Power Sequence (PPS) powers the PHY before state verification runs.
