This replaces [1] and [2]. The main changes since then: - A device link between i915 and HDA (added meanwhile as a separate change). - Split the CDCLK change to happen before or after any updates to the pipe depending on whether we're increasing or decreasing CDCLK. - Wait for vblank after an optimized CDCLK update. Abhay confirmed that the patchset fixes the audio issues his team saw due to too low CDCLK.
