Merge tag 'pwm/for-5.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm
Pull pwm updates from Thierry Reding: "Quite a large number of conversions this time around, courtesy of Uwe who has been working tirelessly on these. No drivers of the legacy API are left at this point, so as a next step the old API can be removed. Support is added for a few new devices such as the Xilinx AXI timer- based PWMs and the PWM IP found on Sunplus SoCs. Other than that, there's a number of fixes, cleanups and optimizations" * tag 'pwm/for-5.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm: (43 commits) pwm: pwm-cros-ec: Add channel type support dt-bindings: google,cros-ec-pwm: Add the new -type compatible dt-bindings: Add mfd/cros_ec definitions pwm: Document that the pinstate of a disabled PWM isn't reliable pwm: twl-led: Implement .apply() callback pwm: lpc18xx: Implement .apply() callback pwm: mediatek: Implement .apply() callback pwm: lpc32xx: Implement .apply() callback pwm: tegra: Implement .apply() callback pwm: stmpe: Implement .apply() callback pwm: sti: Implement .apply() callback pwm: pwm-mediatek: Add support for MediaTek Helio X10 MT6795 dt-bindings: pwm: pwm-mediatek: Add documentation for MT6795 SoC pwm: tegra: Optimize period calculation pwm: renesas-tpu: Improve precision of period and duty_cycle calculation pwm: renesas-tpu: Improve maths to compute register settings pwm: renesas-tpu: Rename variables to match the usual naming pwm: renesas-tpu: Implement .apply() callback pwm: renesas-tpu: Make use of devm functions pwm: renesas-tpu: Make use of dev_err_probe() ...
