Hello, This series adds a clock driver for the ZynqMP. On ZynqMP, Barebox does not have direct access to the hardware but needs to go through the firmware to configure the clock tree. Patches 1 and 2 update how firmware device tree nodes are populated. The behavior for this is copied from Linux. Patch 3 provides the size of the return value from the ZynqMP firmware to firmware client drivers. This is necessary to use the "query" call. Patch 4 adds the actual driver. Patches 5 and 6 add the firmware to the device tree and connect various devices to the clock controller.
