3 The Maxim MAX8997 is a multi-function device which includes voltage and
4 current regulators, rtc, charger controller and other sub-blocks. It is
5 interfaced to the host controller using a i2c interface. Each sub-block is
7 describes the bindings for 'pmic' sub-block of max8997.
10 - compatible: Should be "maxim,max8997-pmic".
11 - reg: Specifies the i2c slave address of the pmic block. It should be 0x66.
13 - max8997,pmic-buck1-dvs-voltage: A set of 8 voltage values in micro-volt (uV)
17 - max8997,pmic-buck2-dvs-voltage: A set of 8 voltage values in micro-volt (uV)
21 - max8997,pmic-buck5-dvs-voltage: A set of 8 voltage values in micro-volt (uV)
25 [1] If none of the 'max8997,pmic-buck[1/2/5]-uses-gpio-dvs' optional
26 property is specified, the 'max8997,pmic-buck[1/2/5]-dvs-voltage'
30 If either of the 'max8997,pmic-buck[1/2/5]-uses-gpio-dvs' optional
32 'max8997,pmic-buck[1/2/5]-dvs-voltage' should be specified.
35 - interrupts: Interrupt specifiers for two interrupt sources.
36 - First interrupt specifier is for 'irq1' interrupt.
37 - Second interrupt specifier is for 'alert' interrupt.
38 - charger-supply: regulator node for charging current.
39 - max8997,pmic-buck1-uses-gpio-dvs: 'buck1' can be controlled by gpio dvs.
40 - max8997,pmic-buck2-uses-gpio-dvs: 'buck2' can be controlled by gpio dvs.
41 - max8997,pmic-buck5-uses-gpio-dvs: 'buck5' can be controlled by gpio dvs.
44 - max8997,pmic-ignore-gpiodvs-side-effect: When GPIO-DVS mode is used for
46 that of another buck, which is the side effect of the change (set_voltage).
49 - max8997,pmic-buck125-default-dvs-idx: Default voltage setting selected from
54 - max8997,pmic-buck125-dvs-gpios: GPIO specifiers for three host gpio's used
58 included in a sub-node named 'regulators'. Regulator nodes included in this
59 sub-node should be of the format as listed below.
65 The following are the names of the regulators that the max8997 pmic block
66 supports. Note: The 'n' in LDOn and BUCKn represents the LDO or BUCK number
69 - LDOn
70 - valid values for n are 1 to 18 and 21
71 - Example: LDO0, LD01, LDO2, LDO21
72 - BUCKn
73 - valid values for n are 1 to 7.
74 - Example: BUCK1, BUCK2, BUCK3, BUCK7
76 - ENVICHG: Battery Charging Current Monitor Output. This is a fixed
79 - ESAFEOUT1: (ldo19)
80 - ESAFEOUT2: (ld020)
82 - CHARGER_CV: main battery charger voltage control
83 - CHARGER: main battery charger current control
84 - CHARGER_TOPOFF: end of charge current threshold level
