One noteworthy change is that PWM consumers can now pass a hint to the PWM core about the PWM usage, enabling PWM providers to implement various optimizations. There's also a fair bit of simplification here with the addition of some device-managed helpers as well as unification between the DT and ACPI firmware interfaces" * tag 'pwm/for-5.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm: (50 commits) pwm: Remove redundant assignment to pointer pwm pwm: ep93xx: Fix read of uninitialized variable ret pwm: ep93xx: Prepare clock before using it pwm: ep93xx: Unfold legacy callbacks into ep93xx_pwm_apply() pwm: ep93xx: Implement .apply callback pwm: vt8500: Only unprepare the clock after the pwmchip was removed pwm: vt8500: Drop if with an always false condition pwm: tegra: Assert reset only after the PWM was unregistered pwm: tegra: Don't needlessly enable and disable the clock in .remove() pwm: tegra: Don't modify HW state in .remove callback pwm: tegra: Drop an if block with an always false condition pwm: core: Simplify some devm_*pwm*() functions pwm: core: Remove unused devm_pwm_put() pwm: core: Unify fwnode checks in the module pwm: core: Reuse fwnode_to_pwmchip() in ACPI case pwm: core: Convert to use fwnode for matching docs: firmware-guide: ACPI: Add a PWM example dt-bindings: pwm: pwm-tiecap: Add compatible string for AM64 SoC dt-bindings: pwm: pwm-tiecap: Convert to json schema pwm: sprd: Don't check the return code of pwmchip_remove() ... 2021-06-30T22:51:09+00:00 Linus Torvalds torvalds@linux-foundation.org 2021-06-30T22:51:09+00:00 urn:sha1:dbe69e43372212527abf48609aba7fc39a6daa27 Pull networking updates from Jakub Kicinski: "Core: -

In order to avoid an ambiguity, the GPIO polarity is considered being always Active High. Add note about this to the respective documentation file.
