This seems very specific to ST environment,  looking at the driver list from
( [PATCH 4/7] pwm: Align existing pwm drivers with pwm-core ) it seems
most multi SOC environments might support PWM in either one of the SOC.

arch/arm/plat-mxc/pwm.c
arch/arm/plat-pxa/pwm.c
arch/arm/plat-samsung/pwm.c
arch/mips/jz4740/pwm.c
drivers/mfd/twl6030-pwm.c

Unless people have examples of other SOCs which might use this,
the better approach might be to go for a custom driver rather than changing
the framework.

Thanks
