1 * Maxim MAX8998, National/TI LP3974 multi-function device
3 The Maxim MAX8998 is a multi-function device which includes voltage/current
5 other sub-blocks. It is interfaced using an I2C interface. Each sub-block
8 PMIC sub-block
9 --------------
11 The PMIC sub-block contains a number of voltage and current regulators,
17 - compatible: Should be one of the following:
18 - "maxim,max8998" for Maxim MAX8998
19 - "national,lp3974" or "ti,lp3974" for National/TI LP3974.
20 - reg: Specifies the i2c slave address of the pmic block. It should be 0x66.
23 - interrupts: Interrupt specifiers for two interrupt sources.
24 - First interrupt specifier is for main interrupt.
25 - Second interrupt specifier is for power-on/-off interrupt.
26 - max8998,pmic-buck1-dvs-gpios: GPIO specifiers for two host gpios used
27 for buck 1 dvs. The format of the gpio specifier depends on the gpio
29 - max8998,pmic-buck2-dvs-gpio: GPIO specifier for host gpio used
30 for buck 2 dvs. The format of the gpio specifier depends on the gpio
32 - max8998,pmic-buck1-default-dvs-idx: Default voltage setting selected from
36 - max8998,pmic-buck2-default-dvs-idx: Default voltage setting selected from
40 - max8998,pmic-buck-voltage-lock: If present, disallows changing of
43 Additional properties required if max8998,pmic-buck1-dvs-gpios is defined:
44 - max8998,pmic-buck1-dvs-voltage: An array of 4 voltage values in microvolts
45 for buck1 regulator that can be selected using dvs gpio.
47 Additional properties required if max8998,pmic-buck2-dvs-gpio is defined:
48 - max8998,pmic-buck2-dvs-voltage: An array of 2 voltage values in microvolts
49 for buck2 regulator that can be selected using dvs gpio.
