Subject: [PATCH 5/5] ARM: dts: Add max77802 device node for exynos5420-peach-pit
Date: Mon, 9 Jun 2014 11:37:50 +0200 [thread overview]
Message-ID: <1402306670-17041-6-git-send-email-javier.martinez@collabora.co.uk> (raw)
In-Reply-To: <1402306670-17041-1-git-send-email-javier.martinez@collabora.co.uk>
Peach pit board uses a Maxim 77802 Power Management IC to
drive regulators and its Real Time Clock. This patch adds
support for this chip.
These are the device nodes and pinctrl configuration that
is present on the Peach pit DeviceTree source file in the
the Chrome OS kernel 3.8 tree.
