Subject: [PATCH v1 05/14] mfd: twl6040: Register child device for twl6040-pdmclk
Date: Mon, 30 May 2016 11:55:13 +0300 [thread overview]
Message-ID: <20160530085522.30398-6-peter.ujfalusi@ti.com> (raw)
In-Reply-To: <20160530085522.30398-1-peter.ujfalusi@ti.com>
The McPDM in OMAP4/5 is using the pdmclk from twl6040 as functional clock.
The twl6040-pdmclk driver provides a clock which can be used to make sure
that the pdmclk is active when the McPDM is in use.
