Subject: [PATCH] arm64: dts: meson: add A1 periphs and PLL clock nodes
Date:   Wed, 11 Dec 2019 15:08:34 +0800
Message-ID: <20191211070835.83489-1-jian.hu@amlogic.com>

Precedence: bulk

Add A1 periphs and PLL clock controller nodes, Some clocks
in periphs controller are the parents of PLL clocks, Meanwhile
some clocks in PLL controller are those of periphs clocks.
They rely on each other. Compared with the previous series,
the register region is only for the clock. So syscon is not
used in A1.
