[PATCH 2/3] ARM: dts: meson8: add the DDR clock controller

From: Martin Blumenstingl
Date: Sun Dec 08 2019 - 13:05:53 EST


Add the DDR clock controller and pass it's DDR_CLKID_DDR_PLL to the main
(HHI) clock controller as "ddr_clk". The "ddr_clk" is used as one of the
inputs for the audio clock muxes.
