Subject: ARM: dts: STiH407-family: Provide interconnect clock for consumption in ST SDHCI
From: Lee Jones <lee.jones@xxxxxxxxxx>
commit 78567f135d9bbbaf4538f63656d3e4d957c35fe9 upstream.
The STiH4{07,10} platform contains some interconnect clocks which are used
by various IPs. If these clocks aren't handled correctly by ST's SDHCI
driver MMC will break and the following output can be observed:
[ 13.916949] mmc0: Timeout waiting for hardware interrupt.
