-This binding represents the on-chip eFuse OTP controller found on
-i.MX6Q/D, i.MX6DL/S, i.MX6SL, i.MX6SX, i.MX6UL, i.MX6ULL/ULZ, i.MX6SLL,
-i.MX7D/S, i.MX7ULP, i.MX8MQ, i.MX8MM, i.MX8MN and i.MX8MP SoCs.

-Required properties:
-- compatible: should be one of
- "fsl,imx6q-ocotp" (i.MX6Q/D/DL/S),
- "fsl,imx6sl-ocotp" (i.MX6SL), or
- "fsl,imx6sx-ocotp" (i.MX6SX),

- "fsl,imx8mp-ocotp" (i.MX8MP),
- followed by "syscon".
-- #address-cells : Should be 1
-- #size-cells : Should be 1
-- reg: Should contain the register base and length.
-- clocks: Should contain a phandle pointing to the gated peripheral clock.
