2901f89170 drivers/pwm: fix pwm_qmsi_set_values() return error
When user wants to set all the PWM ports in one call,
pwm_qmsi_set_values() should call __set_one_port() for
each PWM port. The current pwm_qmsi_set_values() will
return after setting the first PWM port. It's illogical.

58ed60457c pwm/dw: Make config_info pointers const.
Mutable driver state relocated from config_info to driver_info.

This driver is unused by any board, nor can it be compiled for any
board.  Hence this patch reflects the mechanical change that should be
made to the driver in order to support a const config_info, but the
patch has been neither compiled, nor tested.

aba245daad drivers qmsi: Fix power management with reentrancy disabled
The new device control API added a 'device_power_state' variable to the
driver's data structure to keep track of the current power state set
for a device. This member variable is conditionally built into the
runtime data structure of each driver, but in some cases the whole data
structure is conditional on its respective API_REENTRANCY config
variable.

In those cases where the runtime data was previously used only for
reentrancy protection, the runtime data pointer used for device
initialization is NULL, and when power management is enabled, this
invalid pointer ends up dereferenced to get the device_power_state
member.

Make the declaration of the runtime data dependent on any of its
conditional members, and NULL only when all of those settings are
disabled.

6e367c4db0 pwm: k64_ftm: Move suspend and resume hooks to pm_ops
The suspend and resume hooks in the pwm_driver_api struct are relics
from before the current power management infrastructure was in place.
The correct way to implement this now is through the device_pm_ops
struct, by way of the DEFINE_DEVICE_PM_OPS and DEVICE_AND_API_INIT_PM
macros, which make the hooks available through a generic mechanism for
all devices, rather than using per-type APIs.

Since the existing pwm_suspend() and pwm_resume() functions don't check
if the driver_api hooks are NULL, there's now a place holder function
to prevent breaking functionality until the hooks are removed.
