Merge tag 'pwm/for-4.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm
Pull pwm updates from Thierry Reding:
"This set contains mostly fixes to existing drivers as well as cleanup
of code that's not been in active use for a while"
* tag 'pwm/for-4.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm: (27 commits)
acpi: lpss: call pwm_add_table() for BSW PWM device
pwm: Try to load modules during pwm_get()
pwm: Don't hold pwm_lookup_lock longer than necessary
pwm: Make the PWM_POLARITY flag in DTB optional
pwm: Print error messages with pr_err() instead of pr_debug()
pwm: imx: Add polarity inversion support to i.MX's PWMv2
pwm: imx: doc: Update imx-pwm.txt documentation entry
pwm: imx: Remove redundant i.MX PWMv2 code
pwm: imx: Provide atomic PWM support for i.MX PWMv2
pwm: imx: Move PWMv2 wait for fifo slot code to a separate function
pwm: imx: Move PWMv2 software reset code to a separate function
pwm: imx: Rewrite v1 code to facilitate switch to atomic PWM
pwm: imx: Add separate set of PWM ops for v1 and v2
pwm: imx: Remove ipg clock and enable per clock when required
pwm: lpss: Add Intel Gemini Lake PCI ID
pwm: lpss: Do not export board infos for different PWM types
pwm: lpss: Avoid reconfiguring while UPDATE bit is still enabled
pwm: lpss: Switch to new atomic API
pwm: lpss: Allow duty cycle to be 0
