Subject: [alsa-devel] [PATCH v2] ASoC: intel: Add Broadwell rt5650 machine driver
Date: Wed,  4 Dec 2019 16:15:58 -0800
Message-ID: <20191205001605.229405-1-cujomalainey@chromium.org> (raw)

From: Ben Zhang <benzh@chromium.org>

Add machine driver for Broadwell + rt5650.

v2 (Curtis):
* Addressed Pierre's comments
  * Added SOF dependencies
  * Added platform override
  * Fixed Kconfig
* Moved to devm register
