Merge tag 'pwm/for-5.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm
Pull pwm updates from Thierry Reding: "Mostly cleanups and minor improvements with some new chip support for some drivers" * tag 'pwm/for-5.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm: (37 commits) pwm: Remove set but not set variable 'pwm' pwm: sun4i: Initialize variables before use pwm: stm32: Remove automatic output enable pwm: sun4i: Narrow scope of local variable pwm: bcm2835: Allow building for ARCH_BRCMSTB pwm: imx27: Eliminate error message for defer probe pwm: sun4i: Fix inconsistent IS_ERR and PTR_ERR pwm: sun4i: Move pwm_calculate() out of spin_lock() pwm: omap-dmtimer: Allow compiling with COMPILE_TEST pwm: omap-dmtimer: put_device() after of_find_device_by_node() pwm: omap-dmtimer: Simplify error handling pwm: omap-dmtimer: Remove PWM chip in .remove before making it unfunctional pwm: Implement tracing for .get_state() and .apply_state() pwm: rcar: Document inability to set duty_cycle = 0 pwm: rcar: Drop useless call to pwm_get_state() pwm: Fix minor Kconfig whitespace issues pwm: atmel: Implement .get_state() pwm: atmel: Use register accessors for channels pwm: atmel: Document known weaknesses of both hardware and software pwm: atmel: Replace loop in prescale calculation by ad-hoc calculation ...
