Subject: [PATCH v3 1/3] ASoC: samsung: Document DT bindings for Midas sound subsystem
Date: Tue, 28 Jul 2020 15:11:09 +0200 [thread overview]
Message-ID: <20200728131111.14334-1-s.nawrocki@samsung.com> (raw)
In-Reply-To: CGME20200728131126eucas1p16365622c52f91104373a2cd3e0ebb619@eucas1p1.samsung.com
This patch adds documentation of DT biding for the Midas sound complex.
Partially based on the *txt version by Simon Shields <simon@lineageos.org>.
Signed-off-by: Sylwester Nawrocki <s.nawrocki@samsung.com>
---
Changes for v3:
- change the sound-dai property type in cpu, codec nodes from
phandle-array to phandle
Changes for v2:
- fix wrong *-gpios entries in the example,
- mark sound-dai properties as required.
