-Rockchip internal OTP (One Time Programmable) memory device tree bindings
-
-Required properties:
-- compatible: Should be one of the following.
- - "rockchip,px30-otp" - for PX30 SoCs.
- - "rockchip,rk3308-otp" - for RK3308 SoCs.
-- reg: Should contain the registers location and size
-- clocks: Must contain an entry for each entry in clock-names.
-- clock-names: Should be "otp", "apb_pclk" and "phy".
-- resets: Must contain an entry for each entry in reset-names.
- See ../../reset/reset.txt for details.
-- reset-names: Should be "phy".
-
-See nvmem.txt for more information.

-Example:
- otp: otp@ff290000 {
- compatible = "rockchip,px30-otp";
- reg = <0x0 0xff290000 0x0 0x4000>;
- #address-cells = <1>;
- #size-cells = <1>;
- clocks = <&cru SCLK_OTP_USR>, <&cru PCLK_OTP_NS>,
- <&cru PCLK_OTP_PHY>;
- clock-names = "otp", "apb_pclk", "phy";
- };
