Subject: [PATCH 14/15] dt-bindings: arm-gic: Drop 'clock-names' from binding document

Commit afbbd2338176 ("irqchip/gic: Document optional Clock and Power
Domain properties") documented optional clock and power-dmoain properties
for the ARM GIC. Currently, there are no users of these and for the
Tegra210 Audio GIC (based upon the GIC-400) there are two clocks, a
functional clock and interface clock, that need to be enabled.

To allow flexibility, drop the 'clock-names' from the GIC binding and
just provide a list of clocks which the driver can parse. It is assumed
that any clocks that are listed, need to be enabled in order to access
the GIC.

Signed-off-by: Jon Hunter <jonathanh@...dia.com>

Please note that I am not sure if this will be popular, but I am trying
to come up with a generic way to handle multiple clocks that may be
required for accessing a GIC.
