Subject: [PATCH] overlays: Make the i2c-gpio overlay safe again
|
|
|
|
Like many overlays, the i2c-gpio overlay goes to efforts to avoid
|
|
generating warnings about #address-cells and #size-cells not
|
|
being defined, which it does by defining them. Unfortunately this
|
|
is fatal if they don't match what the system requires, and the
|
|
recent switch to #size-cells = 2 on 2711 made i2c-gpio very
|
|
dangerous.
|
|
|
|
In the absence of the knowledge of a clean way to fix this, just delete
|
|
the declarations and suffer the warnings.
