Subject: [PATCH 5/6] ARM: dts: meson8: add the DDR clock controller
Date: Sat, 21 Sep 2019 17:18:34 +0200 [thread overview]
Message-ID: <20190921151835.770263-6-martin.blumenstingl@googlemail.com> (raw)
In-Reply-To: <20190921151835.770263-1-martin.blumenstingl@googlemail.com>
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.
