Subject: ARM: dts: vf610-zii-scu4-aib: Specify 'i2c-mux-idle-disconnect'
X-Git-Tag: v5.15~4939^2~22^2~12
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=71936a6d18c33c63b4e9e0359fb987306cbe9fae;p=platform%2Fkernel%2Flinux-starfive.git

ARM: dts: vf610-zii-scu4-aib: Specify 'i2c-mux-idle-disconnect'

Specify 'i2c-mux-idle-disconnect' for both I2C switches present on the
board, since both are connected to the same parent bus and all of
their children have the same I2C address.
