Subject: [PATCH 3/3] ARM: sun8i: a83t: Add device node for PRCM
Date: Fri, 26 May 2017 16:00:25 +0800	[thread overview]
Message-ID: <20170526080025.28532-4-wens@csie.org> (raw)
In-Reply-To: <20170526080025.28532-1-wens-jdAy2FN1RRM@public.gmane.org>

The A83T's PRCM has the same set of clocks and resets as the A64.
However, a few dividers are different. And due to the lack of a low
speed 32.768 kHz oscillator, a few of the clock parents are different.

The PRCM also has controls for various power domains. These are not
supported yet, neither in software nor in the device tree binding.
