Subject: arm64: dts: X-Gene v1: I2C0 clock is always on
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=0fe8588fcaac6fff08937a338feb8e3082fe9e57;p=linux-beck.git

arm64: dts: X-Gene v1: I2C0 clock is always on

X-Gene v1 I2C0 and I2C1 controllers share the same clock
enable register field. This patch remove clock node for I2C0
and leave I2C0 clock always on as having it toggled on/off
will affect I2C1 operation.
