-  - "nvidia,tegra30-pwm"
+- compatible: For Tegra20, must contain "nvidia,tegra20-pwm".  For Tegra30,
+  must contain "nvidia,tegra30-pwm".  Otherwise, must contain
+  "nvidia,<chip>-pwm", plus one of the above, where <chip> is tegra114,
+  tegra124, tegra132, or tegra210.
 - reg: physical base address and length of the controller's registers
