Subject: [PATCH 2/2] pinctrl: pinctrl-imx8mq: Add support PM operations
Date: Mon, 25 Mar 2019 13:48:51 +0000 [thread overview]
Message-ID: <1553521721-12061-2-git-send-email-abel.vesa@nxp.com> (raw)
In-Reply-To: <1553521721-12061-1-git-send-email-abel.vesa@nxp.com>
Add suspend/resume pm ops to the pinctrl i.MX8MQ driver.
Make the suspend late and the resume early since some of the
pins might be needed active very late.
These call the pinctrl-imx generic handlers.
