Hi,
Here are two patches to bring support for a new hardware based on SAM9G25 SoC.
The first one adds the PIN controller definition for PWM0.
The second defines the new board.
Changes since v1:
- drop useless comments
- move pwm0 pinctrl's node close to tcb0
- drop ek boards from compatible machine
- add at91sam9g25 board to compatible machine
Changes since v2:
- update to v4.0
- fix alphabetical order between gpio_keys and pwm_leds
Changes since v3:
- add num-ports = <1> attribute to ohci node
Changes since v4:
- update to v4.0.1
- update "Acked-by" list
Best regards,
Gaël PORTAY (2):
ARM: at91/dt: sam9x5: add pinctrl for pwm0

Not needed as already included in at91sam9g25.dtsi: I remove it before
applying the patch.
