Subject: [GIT PULL] pwm: Changes for v6.17-rc1
Hello Linus,
the following changes since commit e04c78d86a9699d136910cfc0bdcf01087e3267e:
Linux 6.16-rc2 (2025-06-15 13:49:41 -0700)
are available in the Git repository at:

pwm: Changes for v6.17-rc1
Apart from the usual mix of new drivers (pwm-argon-fan-hat), adding
support for variants to existing drivers, minor improvements to both
drivers and docs, device tree documenation updates, the noteworthy
changes are:
- A pull of pm-runtime-6.17-rc1 to make it possible to apply
a582469541a3 ("pwm: img: Remove redundant pm_runtime_mark_last_busy()
calls"). Note this updates the base for my tree to 6.16-rc2.
- A hwmon companion driver to pwm-mc33xs2410 living in drivers/hwmon
and acked by Guenter Roeck
- chardev support for PWM devices
This leverages atomic PWM updates to userspace and at the same time
simplifies and accelerates PWM configuration changes.
----------------------------------------------------------------
Lee provided another immutable branch containing patches by Nuno Sá,
including PWM changes at
git://git.kernel.org/pub/scm/linux/kernel/git/lee/mfd.git ib-mfd-gpio-input-pwm-v6.17
, but I didn't merge it as there is no conflict with my tree and so I
don't see a benefit in polluting the diffstat of this PR. The pwm
related changes in there of course have my blessing anyhow.
The three topmost patches are in next only since next-20250725, the
others are in next since next-20250710. Two of the three "new" patches
are quite simple. The third is the hwmon change, that I didn't want to
hold back to free both the hwmon guys and me from the need to coordinate
this change for a whole development cycle.
I considered waiting a bit with my PR to give these changes a bit more
exposure in next, but giving your travel plans I decided to create it
early as usual.
Diffstat below and thanks too all contributors.
Please pull the pwm/for-6.17-rc1 tag into 6.17-rc1.
Thanks
Uwe
