Subject: [PATCH v5 4/9] ARM: STi: DT: STiH407: Add Device Tree node for the LPC
Date: Wed,  4 Mar 2015 18:06:33 +0000	[thread overview]
Message-ID: <1425492398-27340-5-git-send-email-lee.jones@linaro.org> (raw)
In-Reply-To: <1425492398-27340-1-git-send-email-lee.jones@linaro.org>

On current ST platforms the LPC controls a number of functions.  This
patch enables support for the LPC Watchdog and LPC RTC devices on LPC1
and LPC2 respectively.
