Subject: ARM: dts: aspeed: catalina: add i2c-mux-idle-disconnect to all mux
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=28805afcc74b1a6b6583dc463bd352d251436d28;p=users%2Fjedix%2Flinux-maple.git

ARM: dts: aspeed: catalina: add i2c-mux-idle-disconnect to all mux

Add the `i2c-mux-idle-disconnect` property to all i2c-mux nodes to
ensure proper behavior when switching between multiple I2C buses.
This avoids potential confusion caused by device addresses appearing on
multiple buses when they are not actively selected.
