2012-07-23pwm: pwm-mxs: encode soc name in compatible stringShawn Guo1-2/+2
Encode soc name in the compatible string to know the specific version hardware block. This is the general approach adopted for most bindings. Change mxs-pwm binding to use the approach. Signed-off-by: Shawn Guo <shawn.guo@linaro.org> Signed-off-by: Thierry Reding <thierry.reding@avionic-design.de>
