Device Tree • Re: PWM driver questions

I am trying to do what cleverca22 and aBUGSworstnightmare suggested and add compatible to the PWM in the device tree and then have the driver loaded via compatible value. The issue I have is when I add compatible to the overlay node target=<&pwm> the setting of pin12 and alt func 4 stop being applied.

In short how do I get my compatible set at the same time as redefining pin12 to alt func4?

Code:

/dts-v1/;/plugin/;/ {compatible = "brcm,bcm2835";fragment@0 {target = <&gpio>;__overlay__ {pwm_pins: pwm_pins {brcm,pins = <12>;brcm,function = <4>;};};};fragment@1 {target = <&pwm>;__overlay__ {pinctrl-names = "default";/*    I have tried this here with no luck *//*                      compatible = "williespwm";   */pinctrl-0 = <&pwm_pins>;assigned-clock-rates = <10000000>;status = "okay";};};};

Thanks
