[PATCH AUTOSEL 6.14 601/642] ASoC: hdmi-codec: allow to refine formats actually supported

[Sasha Levin <sashal@kernel.org>]

From: Olivier Moysan <olivier.moysan@foss.st.com>

[ Upstream commit 038f79638e0676359e44c5db458d52994f9b5ac1 ]

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.
