Subject: [PATCH v4 10/14] ASoC: dt-bindings: Add WCD9335 MBHC specific properties
Date: Sun, 16 Sep 2018 17:57:23 -0700	[thread overview]
Message-ID: <20180917005727.32728-11-srinivas.kandagatla@linaro.org> (raw)
In-Reply-To: <20180917005727.32728-1-srinivas.kandagatla@linaro.org>

From: Srinivas Kandagatla <srinivas.kandagatla@linaro.org>

This patch add new bindings required to support MBHC
(Multi Button Headset Control) block in the codec.
This block is used for jack insert/removal detection,
headset type detection and 8 button press/release events.

All these properties are very much specific to board.
