Merge tag 'pwm/for-6.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm
Pull pwm updates from Thierry Reding: "The bulk of this is trivial conversions to the new .remove_new() callback for drivers as part of Uwe's effort to clean that up. Other than that a driver is added for Apple devices and various small fixes are included for existing drivers. Last but not least, this finally gets rid of the old pwm_request() and pwm_free() APIs are removed since the last user was dropped in v6.3" * tag 'pwm/for-6.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm: (44 commits) pwm: Remove unused radix tree pwm: Delete deprecated functions pwm_request() and pwm_free() pwm: meson: Fix g12a ao clk81 name pwm: meson: Fix axg ao mux parents pwm: stm32: Enforce settings for PWM capture MAINTAINERS: Add entries for Apple PWM driver pwm: Add Apple PWM controller dt-bindings: pwm: Add Apple PWM controller pwm: mtk-disp: Configure double buffering before reading in .get_state() pwm: mtk-disp: Disable shadow registers before setting backlight values pwm: stm32-lp: Drop of_match_ptr for ID table pwm: rcar: Drop of_match_ptr for ID table dt-bindings: pwm: Convert Amlogic Meson PWM binding dt-bindings: pwm: mediatek: Add mediatek,mt7986 compatible pwm: xilinx: Convert to platform remove callback returning void pwm: vt8500: Convert to platform remove callback returning void pwm: tiehrpwm: Convert to platform remove callback returning void pwm: tiecap: Convert to platform remove callback returning void pwm: tegra: Convert to platform remove callback returning void pwm: sun4i: Convert to platform remove callback returning void ...
