Convert documentation from txt format to yaml. Add documentation about reset-gpio. Set reset gpio to high on ak8975_power_on, set reset gpio to low on ak8975_power_off. Without setting it to high on ak8975_power_on driver's probe fails on ak8975_who_i_am while checking for device identity for AK09911 chip AK09911 has a reset gpio to handle register's reset. If reset gpio is set to low it will trigger the reset. AK09911 datasheed says that if not used reset pin should be connected to VID and this patch emulates this situation Jonathan Albrieux (3): dt-bindings: iio: magnetometer: ak8975: convert txt format to yaml dt-bindings: iio: magnetometer: ak8975: add gpio reset support iio: magnetometer: ak8975: Add gpio reset support .../bindings/iio/magnetometer/ak8975.txt | 30 -------- .../bindings/iio/magnetometer/ak8975.yaml | 70 +++++++++++++++++++ drivers/iio/magnetometer/ak8975.c | 21 +++++- 3 files changed, 89 insertions(+), 32 deletions(-) delete mode 100644 Documentation/devicetree/bindings/iio/magnetometer/ak8975.txt create mode 100644 Documentation/devicetree/bindings/iio/magnetometer/ak8975.yaml -- 2.17.1
