Merge tag 'intel-pinctrl-v6.2-2' of git://git.kernel.org/pub/scm/linux/kernel/git/pinctrl/intel into devel
intel-pinctrl for v6.2-2
* Enable PWM feature on Intel pin control IPs
The following is an automated git shortlog grouped by driver:
intel:
- Enumerate PWM device when community has a capability
pwm:
- lpss: Rename pwm_lpss_probe() --> devm_pwm_lpss_probe()
- lpss: Allow other drivers to enable PWM LPSS
- lpss: Include headers we are the direct user of
- lpss: Rename MAX_PWMS --> LPSS_MAX_PWMS
- Add a stub for devm_pwmchip_add()
