Subject: [RFC PATCH 7/9] clk: sunxi-ng: add support for suniv SoC
Date: Sat, 20 Jan 2018 07:17:33 +0800 [thread overview]
Message-ID: <20180119231735.61504-8-icenowy@aosc.io> (raw)
In-Reply-To: <20180119231735.61504-1-icenowy@aosc.io>
The suniv SoC (the chip in some new F-series products of Allwinner) has
a CCU which seems to be a stripped version of the CCU in SoCs after
sun6i.
Add support for the CCU.
