Merge tag 'pwm/for-4.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm
Pull pwm updates from Thierry Reding: "This series contains a number of improvements to existing drivers, such as LPSS. Some drivers, such as renesas-tpu and rcar get support for more SoC generations. To round things off this fixes an issue with the sysfs interface" * tag 'pwm/for-4.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm: pwm: lpss: Only set update bit if we are actually changing the settings pwm: lpss: Force runtime-resume on suspend on Cherry Trail pwm: Enable TI ECAP driver for ARCH_K3 dt-bindings: pwm: tiecap: Add TI AM654 SoC specific compatible dt-bindings: pwm: rcar: Add r8a774a1 support pwm: Send a uevent on the pwmchip device upon channel sysfs (un)export Revert "pwm: Set class for exported channels in sysfs" dt-bindings: pwm: renesas-tpu: Document r8a7744 support dt-bindings: pwm: rcar: Add r8a7744 support dt-bindings: pwm: renesas: tpu: Document R8A779{7|8}0 bindings dt-bindings: pwm: renesas: pwm-rcar: Document R8A779{7|8}0 bindings dt-bindings: pwm: renesas: tpu: Fix "compatible" prop description pwm: Use SPDX identifier for Renesas drivers pwm: lpss: Add get_state callback pwm: lpss: Release runtime-pm reference from the driver's remove callback pwm: lpss: Check PWM powerstate after resume on Cherry Trail devices pwm: lpss: Move struct pwm_lpss_chip definition to the header file pwm: lpss: Add ACPI HID for second PWM controller on Cherry Trail devices ACPI / PM: Export acpi_device_get_power() for use by modular build drivers pwm: tegra: Remove gratuituous blank line
