[PATCH v2 0/2] ARM: dts: sun8i: v3s: add pwm controller to v3s dts

[Tobias Schramm]

This patchset adds the pwm controller to the Allwinner V3s dts. The PWM
controller is compatible with the one found in the Allwinner A20.

This is v2 of this patchset.

Cheers,
Tobias

[PATCH v2 1/2] dt-bindings: pwm: allwinner: add v3s pwm compatible

[Tobias Schramm]

The Allwinner V3s pwm peripheral is compatible with the pwm peripheral
inside the Allwinner A20.
This patch adds a compatible string for it.

Compared the A20 and V3s manuals, the register description on the
PWM peripherals look indeed identical.

[PATCH v2 2/2] ARM: dts: sun8i: v3s: add pwm controller to v3s dts

[Tobias Schramm]

The Allwinner V3s and V3 SoCs feature a pwm controller identical to the
one used in the Allwinner A20.
This commit adds it to the V3s dtsi.

Address and size match the manual, and the register description look
identical between A20 and V3s.
