Subject: [PATCH] ASoC: hdmi-codec: allow to refine formats actually supported
Currently the hdmi-codec driver registers all the formats that are
allowed on the I2S bus. Add i2s_formats field to codec data, to allow
the hdmi codec client to refine the list of the audio I2S formats
actually supported.
