Subject: [PATCH 2/5] ASoC: cs35l35: Add device tree binding for I2S drive configuration
Date: Wed, 8 Mar 2017 16:42:48 +0000 [thread overview]
Message-ID: <1488991371-22513-2-git-send-email-ckeepax@opensource.wolfsonmicro.com> (raw)
In-Reply-To: <1488991371-22513-1-git-send-email-ckeepax@opensource.wolfsonmicro.com>
Add a binding for setting how the I2S pins are driven in unused slots,
currently the chip will just use the default of drive 0, however
this causes issues when multiple devices are attached to the same bus.
