dts: bindings: trivial clock bindings doc fixes
fix a typo in the "clock specifiers" discussion, clarify that clock specifiers (the integer cells part that goes with the phandle) may be empty Cc: Rob Herring <rob.herring@calxeda.com> Cc: Pawel Moll <pawel.moll@arm.com> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Stephen Warren <swarren@wwwdotorg.org> Cc: Ian Campbell <ijc+devicetree@hellion.org.uk> Cc: devicetree@vger.kernel.org Acked-by: Mark Rutland <mark.rutland@arm.com> Signed-off-by: Gerhard Sittig <gsi@denx.de> Signed-off-by: Rob Herring <robh@kernel.org>

outputs to clock inputs. Similar to the gpio specifiers, a clock

specifier is an array of zero, one or more cells identifying the clock

value of a #clock-cells property in the clock provider node.
