Subject: [PATCH] ARM: dts: vf610-zii-scu4-aib: Specify 'i2c-mux-idle-disconnect'
Date: Thu, 3 Oct 2019 22:41:15 -0700 [thread overview]
Message-ID: <20191004054115.26082-1-andrew.smirnov@gmail.com> (raw)
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.
Fixes: ca4b4d373fcc ("ARM: dts: vf610: Add ZII SCU4 AIB board")

Shawn:
If this is possible, I'd like this one to go into 5.4.
Thanks,
