Subject: arm: dts: armada-38x-solidrun-microsom: configure i2c0 bus
X-Git-Url: http://git.dujemihanovic.xyz/html/static/%7B%7B%20.Permalink%20%7D%7D?a=commitdiff_plain;h=52f7530e2d0f432d6978affc12732c756b522b85;p=u-boot.git

arm: dts: armada-38x-solidrun-microsom: configure i2c0 bus

SolidRun Armada-388 SoM has an i2c bus supporting on-som eeprom, and
peripherals on a carrier.
armada-38x.dtsi disables this bus by default, it should be enabled by
som or carrier dts.

Linux has moved i2c0 from helios-4 board dts to som dtsi, including
status, pinctrl and clock speed.
Copy these settings from mainline.

This fixes accessing i2c bus from u-boot commandline.
