[PATCH] dt-bindings: clock: brcm,iproc-clocks: fix armpll properties

From: Rafał Miłecki <zajec5@gmail.com>
Date: 2021-08-19 05:29:41
Also in: linux-arm-kernel, linux-clk
Subsystem: common clk framework, open firmware and flattened device tree bindings, the rest · Maintainers: Michael Turquette, Stephen Boyd, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds

From: Rafał Miłecki <rafal@milecki.pl>

armpll clocks (available on Cygnus and Northstar Plus) are simple clocks
with no cells. Adjust binding props #clock-cells and clock-output-names
to handle them.
