| This driver supports both i.MX6SX and i.MX7D PWM. |
| The compatible string is named "imx27" because the hardware module is the |
| same module present starting from imx27 CPUs and this driver can potentially |
| support other CPUs with imx27 module. This is also the same string used |
| in the Linux kernel. |
| |
| compatible: "fsl,imx27-pwm" |
