Subject: [PATCH 0/6] ZynqMP clock driver
Date: Tue, 12 Mar 2019 11:20:49 +0100	[thread overview]
Message-ID: <20190312102055.12386-1-m.tretter@pengutronix.de> (raw)

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.

Michael
