Subject: [PATCH] ARM: DTS: CROS5250: Add max77686 device tree support
Date: Wed, 28 Nov 2012 16:21:40 +0530 [thread overview]
Message-ID: <1354099900-24779-1-git-send-email-a.kesavan@samsung.com> (raw)
The exynos5250 based chromebooks have a max77686 pmic on i2c channel 0.
Add support for the pmic in the common cros5250 dts file.
Tested after enabling cpufreq support for exynos5250 SoC and varying the
arm frequency/voltage using the userspace governer.
