[Intel-gfx] [PATCH] drm/i915/display: Do both crawl and squash when changing cdclk

2022-09-27 Thread Anusha Srivatsa
From: Ville Syrjälä For MTL, changing cdclk from between certain frequencies has both squash and crawl. Use the current cdclk config and the new(desired) cdclk config to construtc a mid cdclk config. Set the cdclk twice: - Current cdclk -> mid cdclk - mid cdclk -> desired cdclk v2: Add check in
