Hi Dafna, cc'ing Wolfram and linux-i2c ML Missatge de Dafna Hirschfeld <dafna.hirschfeld@collabora.com> del dia dj., 27 de febr. 2020 a les 15:58: > > Convert the binding file i2c-cros-ec-tunnel.txt to yaml format. > > This was tested and verified on ARM and ARM64 with: > > make dt_binding_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/i2c/google,cros-ec-i2c-tunnel.yaml > make dtbs_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/i2c/google,cros-ec-i2c-tunnel.yaml > > Signed-off-by: Dafna Hirschfeld <dafna.hirschfeld@collabora.com> From my side: Reviewed-by: Enric Balletbo i Serra <enric.balletbo@collabora.com> We still need Rob's review and as this is a driver in the I2C subsystem I assume this should go through the Wolfram's tree (note that was not cc'ied, it is now). I can also pick the patch through platform-chrome tree if Wolfram is fine.
