[PATCH v3 1/2] dt-bindings: pwm: Allow decimal format in addition to hex format

[Tony Lindgren]

Let's allow node numbering in decimal format too.

Simple human-readable increments/IDs are usually decimal, hex is only for
addresses as noted by Krzysztof Kozlowski <krzysztof.kozlowski at linaro.org>.

Let's use an improved match suggested by Krzysztof Kozlowski
<krzysztof.kozlowski at linaro.org> and improved a bit by Uwe Kleine-König
<u.kleine-koenig at pengutronix.de>.
