dda59d2424 pwm: xilinx: Make use of devm_pwmchip_alloc() function 
This prepares the pwm-xilinx 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.

4caa211522 pwm: xilinx: Prepare removing pwm_chip from driver data 
This prepares the driver for further changes that will drop struct
pwm_chip chip from struct xilinx_pwm_device. Use the pwm_chip as driver
data instead of the xilinx_pwm_device to get access to the pwm_chip in
xilinx_pwm_remove() without using xilinx_pwm->chip.

This prepares the pwm-vt8500 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.

Also convert the to_vt8500_chip() helper macro to a static inline to
get some type safety.

2eb3ff5f4c pwm: sun4i: Consistently name driver data sun4ichip

	v6.8-rc1:drivers/pwm/pwm-sun4i.c:       struct sun4i_pwm_chip *sun4i_pwm = to_sun4i_pwm_chip(chip);

	v6.8-rc1:drivers/pwm/pwm-sun4i.c:       struct sun4i_pwm_chip *sun4ichip;
	v6.8-rc1:drivers/pwm/pwm-sun4i.c:       struct sun4i_pwm_chip *sun4ichip = platform_get_drvdata(pdev);

"chip" is usually reserved for variables of type struct pwm_chip. So
pick sun4ichip as common name which better matches the type name than
sun4i_pwm.

e315bf700b pwm: stm32: Change prototype of helper that detects npwm to prepare further changes 
When the stm32 pwm driver is converted to pwmchip_alloc(), the number of

allocated. So rework the helper function that determines this number to
not take the driver private data struct as input parameter.

Most functions use "hi_pwm_chip" as name. Make use of this in the
remaining two functions (that used "pwm_chip" before, which isn't
optimal as this is a type name, too).

This prepares the pwm-atmel-hlcdc 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 driver for further changes that will drop struct
pwm_chip chip from struct atmel_hlcdc_pwm. Use the pwm_chip as driver
data instead of the atmel_hlcdc_pwm to get access to the pwm_chip in
the .suspend() and .resume() callbacks and atmel_hlcdc_pwm_remove()
without using atmel->chip.

024913dbf9 pwm: Provide pwmchip_alloc() function and a devm variant of it 
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().

4e59267c7a pwm: Provide an inline function to get the parent device of a given chip 
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.
