Subject: [PATCH 4.14 57/89] ARM64: dts: marvell: armada-cp110: Fix clock resources for various node

4.14-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Gregory CLEMENT <gregory.clement@...e-electrons.com>

commit e3af9f7c6ece29fdb7fe0aeb83ac5d3077a06edb upstream.

On the CP modules we found on Armada 7K/8K, many IP block actually also
need a "functional" clock (from the bus). This patch add them which allows
to fix some issues hanging the kernel:

If Ethernet and sdhci driver are built as modules and sdhci was loaded
first then the kernel hang.

Fixes: bb16ea1742c8 ("mmc: sdhci-xenon: Fix clock resource by adding an optional bus clock")
