Hello Linus,

the following changes since commit 6de23f81a5e08be8fbf5e8d7e9febc72a5b5f27f:

  Linux 7.0-rc1 (2026-02-22 13:18:59 -0800)

are available in the Git repository at:

  https://git.kernel.org/pub/scm/linux/kernel/git/ukleinek/linux.git tags/pwm/for-7.1-rc1

for you to fetch changes up to aa8f35172ab66c57d4355a8c4e28d05b44c938e3:

  pwm: th1520: fix `CLIPPY=1` warning (2026-03-29 09:37:13 +0200)

Very few patches this time around. I think there are a few patches on
the pwm mailing list that might be ready, but I didn't come around to
review them in time for the merge window, so it's just these 5 commits.

All changes are in next since next-20260330, I don't expect any
complications.

Thanks for pulling these into v7.1-rc1.

Best regards
Uwe

pwm: Changes for v7.1-rc1

Just two minor fixes, a device tree binding addition to support a few
more SoCs (without the need for driver adaptions), a driver include
cleanup and the addition of the #linux-pwm irc channel to MAINTAINERS.

  pwm: atmel-tcb: Cache clock rates and mark chip as atomic (2026-04-22 07:24:33 +0200)

While writing the tag text I thought about splitting the "mark chip as
atomic" part of Sangyun's fix into a separate change for the next merge
window. But it's still early in the development cycle and I don't expect
problems here, so I kept the change as it was tested. Also the patch is
a bit unelegant as it results in keeping a clock on during the lifetime
of the driver; I expect this to be addressed in one of the next
development cycles. Compared to the sleep-in-atomic this is a very minor
annoyance and I don't want to delay the fix because of that.

The pwm-stm fix is in next for a week already, the atmel-tcb fix is only
contained since next-20260422 with no problem reports.

Thanks for pulling this into your tree at your convenience,
Uwe

pwm: Two driver fixes

After having added some more code to libpwm checking the pwm rounding
rules for the userspace interface I spotted an issue in the pwm-stm32
driver where in some cases involving inverted polarity the wrong
hardware settings for the duty offset are chosen. I think it has little
practical effect because the duty offset is in most cases an artificial
property of the output waveform. Still it's relevant to get this fixed
because this driver serves as a reference implementation for the still
young waveform API.

The second fix addresses a sleep-in-atomic issue in the pwm-atmel-tcb
driver.
