Subject: [PATCH 0963/1085] dtoverlays: Add a disconnect_on_idle override to
|
|
i2c-mux
|
|
|
|
When running multiple muxes, in order to be able to reuse the
|
|
same address on child buses of different muxes you have to
|
|
disconnect the mux after every transaction.
|
|
|
|
Add an override to select that option.
