Each sub-node is identified using the node's name (or the deprecated regulator-compatible property if present), with valid values listed below. The content of each sub-node is defined by the standard binding for regulators; see regulator.txt. The valid names for regulators are: buck1, buck2, buck3, buck4, buck5, ldo1, ldo2, ldo3, ldo4, ldo5, ldo6, ldo7, ldo8, ldo9, ldo10, ldo11, ldo12, ldo13, ldo14, ldo15, ldo16, ldo17, ldo18, ldo19 Example: pmic: 88pm800@31 { compatible = "marvell,88pm800"; reg = <0x31>; regulators { buck1 { regulator-min-microvolt = <600000>; regulator-max-microvolt = <3950000>; regulator-boot-on; regulator-always-on; }; ldo1 { regulator-min-microvolt = <600000>; regulator-max-microvolt = <15000000>; regulator-boot-on; regulator-always-on; }; ... }; }; drivers/regulator/88pm800.c 0 → 100644 +383 −0 Original line number Diff line number Diff line /* * Regulators driver for Marvell 88PM800 * * Copyright (C) 2012 Marvell International Ltd. * Joseph(Yossi) Hanin <yhanin@marvell.com> * Yi Zhang <yizhang@marvell.com> * * This program is free software; you can redistribute it and/or modify * it under the terms of the GNU General Public License version 2 as * published by the Free Software Foundation. */ #include <linux/module.h> #include <linux/moduleparam.h> #include <linux/init.h> #include <linux/err.h> #include <linux/regmap.h> #include <linux/regulator/driver.h> #include <linux/regulator/machine.h> #include <linux/mfd/88pm80x.h> #include <linux/delay.h> #include <linux/io.h> #include <linux/of.h> #include <linux/regulator/of_regulator.h> /* LDO1 with DVC[0..3] */ #define PM800_LDO1_VOUT (0x08) /* VOUT1 */ #define PM800_LDO1_VOUT_2 (0x09) #define PM800_LDO1_VOUT_3 (0x0A) #define PM800_LDO2_VOUT (0x0B) #define PM800_LDO3_VOUT (0x0C) #define PM800_LDO4_VOUT (0x0D) #define PM800_LDO5_VOUT (0x0E) #define PM800_LDO6_VOUT (0x0F) #define PM800_LDO7_VOUT (0x10) #define PM800_LDO8_VOUT (0x11) #define PM800_LDO9_VOUT (0x12) #define PM800_LDO10_VOUT (0x13) #define PM800_LDO11_VOUT (0x14) #define PM800_LDO12_VOUT (0x15) #define PM800_LDO13_VOUT (0x16) #define PM800_LDO14_VOUT (0x17) #define PM800_LDO15_VOUT (0x18) #define PM800_LDO16_VOUT (0x19) #define PM800_LDO17_VOUT (0x1A) #define PM800_LDO18_VOUT (0x1B) #define PM800_LDO19_VOUT (0x1C) /* BUCK1 with DVC[0..3] */ #define PM800_BUCK1 (0x3C) #define PM800_BUCK1_1 (0x3D) #define PM800_BUCK1_2 (0x3E) #define PM800_BUCK1_3 (0x3F) #define PM800_BUCK2 (0x40) #define PM800_BUCK3 (0x41) #define PM800_BUCK3 (0x41) #define PM800_BUCK4 (0x42) #define PM800_BUCK4_1 (0x43) #define PM800_BUCK4_2 (0x44) #define PM800_BUCK4_3 (0x45) #define PM800_BUCK5 (0x46) #define PM800_BUCK_ENA (0x50) #define PM800_LDO_ENA1_1 (0x51) #define PM800_LDO_ENA1_2 (0x52) #define PM800_LDO_ENA1_3 (0x53) #define PM800_LDO_ENA2_1 (0x56) #define PM800_LDO_ENA2_2 (0x57) #define PM800_LDO_ENA2_3 (0x58) #define PM800_BUCK1_MISC1 (0x78) #define PM800_BUCK3_MISC1 (0x7E) #define PM800_BUCK4_MISC1 (0x81) #define PM800_BUCK5_MISC1 (0x84) struct pm800_regulator_info { struct regulator_desc desc; int max_ua; }; struct pm800_regulators { struct regulator_dev *regulators[PM800_ID_RG_MAX]; struct pm80x_chip *chip; struct regmap *map; }; /* * vreg - the buck regs string. * ereg - the string for the enable register. * ebit - the bit number in the enable register. * amax - the current * Buck has 2 kinds of voltage steps.
