v3: - fix patch messages style - align reset gpio comment to kernel doc reccomendation - introduce changelog. 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 datasheed says that, if not used, reset pin should be connected to VID. This patch emulates this situation.
