[ Upstream commit bd91abb218e0ac4a7402d6c25d383e2a706bb511 ]
This change converts the old binding for the AXI clkgen driver to a yaml format.
As maintainers, added: - Lars-Peter Clausen lars@metafoo.de - as original author of driver & binding - Michael Hennerich michael.hennerich@analog.com - as supporter of Analog Devices drivers
