As there is no GPIO to reset the HiFive Unmatched board, we must directly ask the da9063 PMIC for a reset: this small patchset adds the corresponding sysreset driver and enables it for this board.
As the probing of this new device depends on a device-tree node, this series also adds the device tree bindings documentation for the da9063 device.
Changes in v2: - Add device tree probing as suggested by Heinrich - Rebased onto master
