Subject: [PATCH 2/9] ARM: dts: exynos: Add pinctrl sleep state for 542x i2s module
Date: Fri, 23 Dec 2016 13:24:42 +0100 [thread overview]
Message-ID: <1482495889-6201-3-git-send-email-m.szyprowski@samsung.com> (raw)
In-Reply-To: <1482495889-6201-1-git-send-email-m.szyprowski@samsung.com>
Add a special "sleep" state for Exynos I2S module. This state will be used
to let I2S driver to notify pin controller that it is ready for turning
power off, so the pin controller can also change its runtime state to
suspended and in the result let power domain to turn off.
