2024-02-19pwm: img: Make use of pwmchip_parent() accessorUwe Kleine-König1-8/+8
struct pwm_chip::dev is about to change. To not have to touch this driver in the same commit as struct pwm_chip::dev, use the accessor function provided for exactly this purpose.

struct img_pwm_chip::dev is only assigned to, but the member variable is never used. So drop it. Link: https://lore.kernel.org/r/7b7de753caa453c7fe591228c9a45d0baf8b5878.1707900770.git.u.kleine-koenig@pengutronix.de Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>

struct pwm_chip::dev is about to change. To not have to touch this driver in the same commit as struct pwm_chip::dev, use the accessor function provided for exactly this purpose.

2024-02-15pwm: Provide pwmchip_alloc() function and a devm variant of itUwe Kleine-König1-0/+58
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().

2024-02-15pwm: Provide an inline function to get the parent device of a given chipUwe Kleine-König2-23/+23
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.

2024-02-15pwm: Reorder symbols in core.cUwe Kleine-König1-309/+310
This moves the functions called by pwm consumers above the functions called by pwm providers. When character device support is added later this is hooked into the chip registration functions. As the needed callbacks are a kind of consumer and make use of the consumer functions, having this order is more natural and prevents having to add declarations for static functions. Also move the global variables for pwm tables to the respective functions to have them properly grouped.
