This prepares the pwm-ep93xx driver to further changes of the pwm core outlined in the commit introducing devm_pwmchip_alloc(). There is no intended semantical change and the driver should behave as before.

This prepares the pwm-dwc driver to further changes of the pwm core outlined in the commit introducing devm_pwmchip_alloc().

This prepares the driver for further changes that will drop struct pwm_chip chip from struct dwc_pwm. Use the pwm_chip as driver data and return value of dwc_pwm_alloc() instead of the dwc_pwm to get access to the pwm_chip in dwc_pwm_probe() and dwc_pwm_suspend() without using dwc->chip. Thanks to Raag Jadav for providing a hunk of this patch that Uwe missed during creation of this patch.

This prepares the pwm-cros-ec driver to further changes of the pwm core outlined in the commit introducing devm_pwmchip_alloc(). There is no intended semantical change and the driver should behave as before. The probe function had to be changed a bit because the number of PWMs must be determined before allocation of the pwm_chip and its private data now. Reviewed-by:

pwm_chip allocation and registration is about to change. For that the number of PWM devices must be known earlier in cros_ec_pwm_probe(). So make cros_ec_pwm_get_duty() and cros_ec_num_pwms() independent of struct cros_ec_pwm_device which is only available later. Reviewed-by:

There is already a pointer to the pwmchip, make use of it directly instead of using the struct crystalcove_pwm *crc_pwm just obtained from it. This also has the advantage of not using struct crystalcove_pwm::chip any more which will be dropped soon.

This function allocates a struct pwm_chip and driver data. Compared to the status quo the split into pwm_chip and driver data is new, otherwise it doesn't change anything relevant (yet). The intention is that after all drivers are switched to use this allocation function, its possible to add a struct device to struct pwm_chip to properly track the latter's lifetime without touching all drivers again. Proper lifetime tracking is a necessary precondition to introduce character device support for PWMs (that implements atomic setting and doesn't suffer from the sysfs overhead of the /sys/class/pwm userspace support). The new function pwmchip_priv() (obviously?) only works for chips allocated with pwmchip_alloc().

These functions are useful to store and query driver private data depending on the pwm_chip. After struct pwm_chip got its own struct device, this can make use of dev_get_drvdata() and dev_set_drvdata() on that device. These functions are required already now to convert drivers to pwmchip_alloc() which must happen before changing pwm_chip::dev. Reviewed-by:

Currently a pwm_chip stores in its struct device *dev member a pointer to the parent device. Preparing a change that embeds a full struct device in struct pwm_chip, this accessor function should be used in all drivers directly accessing chip->dev now. This way struct pwm_chip and this new function can be changed without having to touch all drivers in the same change set. Make use of this function in the framework's core sources. Reviewed-by:
