[PATCH 0/4] drm/display: hdmi: provide common code to get Audio Clock Recovery params

[Dmitry Baryshkov]

HDMI standards define a recommended set of values to be used for Audio
Clock Regeneration. Nevertheless, each HDMI driver dealing with audio
implements its own way to determine those values. Implement a common
helper and use it for MSM HDMI (tested), VC4 and DW-HDMI (compile-tested
only) drivers.
