v7: - fix documentation style, removing documentation unnecessary parts v6: - reword documentation for gpios, add interrupt documentation https://lore.kernel.org/linux-iio/20200525151117.32540-1-jonathan.albrieux@xxxxxxxxx/ v5: - add maintainer https://lore.kernel.org/linux-iio/20200520163417.27805-1-jonathan.albrieux@xxxxxxxxx/ v4: - fix some typo - use gpio's dt-bindings for more clarity in documentation - set compatible properties without vendor prefix as deprecated https://lore.kernel.org/linux-iio/20200520073125.30808-1-jonathan.albrieux@xxxxxxxxx/ v3: - fix patch messages style - align reset gpio comment to kernel doc reccomendation - introduce changelog https://lore.kernel.org/linux-iio/20200519124402.26076-1-jonathan.albrieux@xxxxxxxxx/ v2: - rewording of reset gpio comment and patch messages to better clarify reset gpio behaviour https://lore.kernel.org/linux-iio/20200518133645.19127-1-jonathan.albrieux@xxxxxxxxx/ v1: - initial patch submission https://lore.kernel.org/linux-iio/20200519065749.4624-1-jonathan.albrieux@xxxxxxxxx/ Convert documentation from txt format to yaml. Add documentation about reset-gpio. Deassert reset on ak8975_power_on(), assert reset on ak8975_power_off(). Without reset's deassertion during ak8975_power_on(), driver's probe fails on ak8975_who_i_am() while checking for device identity for AK09911 chip. AK09911 has an active low reset gpio to handle register's reset. AK09911 datasheet says that, if not used, reset pin should be connected to VID. This patch emulates this situation.
