Subject: [RFC 4/7] ARM: dts: sun9i: Add PRCM device node for the A80 dtsi
Date: Thu, 14 May 2015 14:10:08 +0800	[thread overview]
Message-ID: <1431583811-25780-5-git-send-email-wens@csie.org> (raw)
In-Reply-To: <1431583811-25780-1-git-send-email-wens@csie.org>

The PRCM is a collection of clock controls, reset controls, and various
power switches/gates. Some of these can be independently listed and
supported, while a number of CPU related ones are used in tandem with
CPUCFG for SMP bringup and CPU hotplugging.
