[PATCH 0/6] ZynqMP clock driver

[Michael Tretter <m.tretter@pengutronix.de>]

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.
