Kernel-4.18.0-80.el8_ltc2978

ltc2978

Required properties:

  • compatible: should contain one of:
    • “lltc,ltc2974”
    • “lltc,ltc2975”
    • “lltc,ltc2977”
    • “lltc,ltc2978”
    • “lltc,ltc2980”
    • “lltc,ltc3880”
    • “lltc,ltc3882”
    • “lltc,ltc3883”
    • “lltc,ltc3886”
    • “lltc,ltc3887”
    • “lltc,ltm2987”
    • “lltc,ltm4675”
    • “lltc,ltm4676”
  • reg: I2C slave address

Optional properties:

  • regulators: A node that houses a sub-node for each regulator controlled by
    the device. Each sub-node is identified using the node’s name, with valid
    values listed below. The content of each sub-node is defined by the
    standard binding for regulators; see regulator.txt.

Valid names of regulators depend on number of supplies supported per device:

  • ltc2974, ltc2975 : vout0 - vout3
  • ltc2977, ltc2980, ltm2987 : vout0 - vout7
  • ltc2978 : vout0 - vout7
  • ltc3880, ltc3882, ltc3886 : vout0 - vout1
  • ltc3883 : vout0
  • ltm4676 : vout0 - vout1

Example:
ltc2978@5e {
compatible = “lltc,ltc2978”;
reg = <0x5e>;
regulators {
vout0 {
regulator-name = “FPGA-2.5V”;
};
vout2 {
regulator-name = “FPGA-1.5V”;
};
};
};
