Hi,
This patchset contain support to make PWM changes configure
and stablize
Following are brief changes done
a. Add support for version2 compatible string
b. Change PWM config and stablize delay in PWM Kona
Praveen Kumar B (3):
dt-bindings: pwm: kona: Add new compatible for new version pwm-kona
drivers: pwm: pwm-bcm-kona: Add pwm-kona-v2 support
ARM: dts: cygnus: Change pwm compatible to new version
