Generic PWM framework driver for Crystalcove (CRC) PMIC based PWM

+obj-$(CONFIG_PWM_CRC) += pwm-crc.o
PWM_CRC is a bool symbol. So pwm-crc.o can never be part of a module.
(If I'm wrong, and that object file can actually be part of a module, you can stop reading here.)

Perhaps this include is not needed.
+static const struct pwm_ops crc_pwm_ops = {
- .config = crc_pwm_config,
- .enable = crc_pwm_enable,
- .disable = crc_pwm_disable,
- .owner = THIS_MODULE,
For built-in only code THIS_MODULE is basically equivalent to NULL (see include/linux/export.h). So I guess this line can be dropped.

Speaking from memory: for built-in only code this is equivalent to calling platform_driver_register(&crystalcove_pwm_driver);
from a wrapper, and marking that wrapper with device_initcall().

These macros will be effectively preprocessed away for built-in only code.
