From a0d183c329165fdd77becba1f58bbe22a5f72ae9 Mon Sep 17 00:00:00 2001 From: Sameer Pujar Date: Wed, 20 Feb 2019 20:43:22 +0530 Subject: ALSA: hda/tegra: property for card name 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.
