Required Properties:

compatible: component name used for driver matching, should be "qcom,qfp-fuse"

compatible: component name used for driver matching, should be "qti,qfp-fuse"

reg: physical base address and length of the register set

qcom,blow-status-offset: offset of the blow status registers.

vdd-blow-supply: regulator used to blow fuses. For backward compatibility, the

regulator name must contain the string vdd-blow.



Optional Properties:

- qti,blow-status-offset: offset of the blow status registers.

  The default offset is 0x204C. Include this only if the blow status register

  is at the different offset.



Example:

	qcom,qfpfuse@fc4b8000 {

		compatible = "qcom,qfp-fuse";

	qti,qfpfuse@fc4b8000 {

		compatible = "qti,qfp-fuse";
