Should this perhaps only be "fsl,imx-tpm"? Sounds to me like this is a hardware block called "TPM" that can be used as a PWM. The compatible string should describe the hardware block, not the mode in which it is used. > +- reg: Physical base address and length of the controller's registers. > +- #pwm-cells: Should be 2.
