The compatible value probably should list both Tegra30 and Tegra20, so
we can know exactly which HW is present, just in case we need to turn
on some bug-fix only for one of the variants:
compatible = "nvidia,tegra30-pwm", "nvidia,tegra20-pwm";
Could you also write binding documentation, in particular explaining
what the two pwm-cells are specifically for Tegra:
Documentation/devicetree/bindings/pwm/nvidia,tegra20-pwm.txt
(although perhaps that'd be part of the previous patch which implements
the driver)
