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";

	};
