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. + +Signed-off-by: Phil Elwell <phil@raspberrypi.com> +--- + arch/arm/boot/dts/overlays/i2c-gpio-overlay.dts | 3 --- + 1 file changed, 3 deletions(-) + +--- a/arch/arm/boot/dts/overlays/i2c-gpio-overlay.dts ++++ b/arch/arm/boot/dts/overlays/i2c-gpio-overlay.dts +@@ -9,9 +9,6 @@ + target-path = "/"; + + __overlay__ { +- #address-cells = <1>; +- #size-cells = <0>; +- + i2c_gpio: i2c@0 { + reg = <0xffffffff>; + compatible = "i2c-gpio"; |
