| Subject: [PATCH] ARM: dts: vf610-zii-scu4-aib: Specify |
| 'i2c-mux-idle-disconnect' |
| |
| commit 71936a6d18c33c63b4e9e0359fb987306cbe9fae upstream. |
| |
| 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") |
