From: Maxime Chevallier maxime.chevallier@bootlin.com Date: Wed, 25 Apr 2018 13:07:31 +0200 Subject: [PATCH] ARM64: dts: marvell: armada-cp110: Add clocks for the xmdio node
The Marvell XSMI controller needs 3 clocks to operate correctly : - The MG clock (clk 5) - The MG Core clock (clk 6) - The GOP clock (clk 18)
This commit adds them, to avoid system hangs when using these interfaces.
