commit 905801fe upstream. CDCLK has to be at least twice the BLCK regardless of audio. Audio driver has to probe using this hook and increase the clock even in absence of any display. v2: Use atomic refcount for get_power, put_power so that we can call each once(Abhay). v3: Reset power well 2 to avoid any transaction on iDisp link during cdclk change(Abhay). v4: Remove Power well 2 reset workaround(Ville). v5: Remove unwanted Power well 2 register defined in v4(Abhay). v6: - Use a dedicated flag instead of state->modeset for min CDCLK changes - Make get/put audio power domain symmetric - Rebased on top of intel_wakeref tracking changes.
