Subject: [PATCH 1/3] ALSA: hda/tegra: property for card name
Date: Wed, 20 Feb 2019 20:43:22 +0530	[thread overview]
Message-ID: <1550675604-14788-1-git-send-email-spujar@nvidia.com> (raw)

An optional property "nvidia,model" is introduced for hda to pass custom
name for the sound card. The suffix "-hda" in the name passed is useful
to distinguish between multiple cards available for a platform.
When the property is not specified, default name("tegra-hda") mentioned
in hda driver is used. This property can be added in platform specific
file of the board and card name can relate to the board in use.
