Subject: [PATCH v6 1/2] i2c: s3c2410: add Sysreg phandle to i2c device nodes
Date: Mon, 24 Nov 2014 14:17:46 +0530 [thread overview]
Message-ID: <1416818867-29156-2-git-send-email-pankaj.dubey@samsung.com> (raw)
In-Reply-To: <1416818867-29156-1-git-send-email-pankaj.dubey@samsung.com>
This patch adds syscon based phandle to i2c device nodes of exynos5250
and exynos5420. These phandles will be used to save restore i2c sysreg
configuration register during s2r from i2c driver.
