The MAX77693 is a companion power management IC for smart phones and tablets.
The MAX77693 contains input over-voltage protection (OVP), a fully-integrated 2.5A switching charger for Lithium Ion battery with integrated battery disconnect, OTG/accessory 5V output power, a high-current white LED driver for camera flash, two safeout LDOs, a haptic motor driver, Model Gauge m3 battery fuel gauge and MicroUSB Interface Controller (MUIC). I2C serial interface is used for communicating. Add MAX77693 node to the Trats2 board. This allows using: - charger regulator, - 2 safeout LDO regulators (for USB OTG), - extcon. Signed-off-by: Krzysztof Kozlowski <[email protected]> Reviewed-by: Javier Martinez Canillas <[email protected]> --- Changes since v1: ================== 1. Use GPIO_ACTIVE_HIGH for gpio flags (suggested by Javier Martinez Canillas). 2. Use regulator node name instead of deprecated regulator-compatible property (suggested by Javier Martinez Canillas). 3. Add Javier Martinez Canillas' reviewed-by tag. --- arch/arm/boot/dts/exynos4412-trats2.dts | 32 ++++++++++++++++++++++++++++++++ 1 file changed, 32 insertions(+) diff --git a/arch/arm/boot/dts/exynos4412-trats2.dts b/arch/arm/boot/dts/exynos4412-trats2.dts index 11967f4561e0..1953317bd658 100644 --- a/arch/arm/boot/dts/exynos4412-trats2.dts +++ b/arch/arm/boot/dts/exynos4412-trats2.dts @@ -14,6 +14,7 @@ /dts-v1/; #include "exynos4412.dtsi" +#include <dt-bindings/gpio/gpio.h> / { model = "Samsung Trats 2 based on Exynos4412"; @@ -22,6 +23,7 @@ aliases { i2c9 = &i2c_ak8975; i2c10 = &i2c_cm36651; + i2c11 = &i2c_max77693; }; memory { @@ -518,6 +520,36 @@ }; }; + i2c_max77693: i2c-gpio-1 { + compatible = "i2c-gpio"; + gpios = <&gpm2 0 GPIO_ACTIVE_HIGH>, <&gpm2 1 GPIO_ACTIVE_HIGH>; + i2c-gpio,delay-us = <2>; + #address-cells = <1>; + #size-cells = <0>; + status = "okay"; + + max77693@66 { + compatible = "maxim,max77693"; + interrupt-parent = <&gpx1>; + interrupts = <5 2>; + reg = <0x66>; + + regulators { + esafeout1_reg: ESAFEOUT1@1 { + regulator-name = "ESAFEOUT1"; + }; + esafeout2_reg: ESAFEOUT2@2 { + regulator-name = "ESAFEOUT2"; + }; + charger_reg: CHARGER@0 { + regulator-name = "CHARGER"; + regulator-min-microamp = <60000>; + regulator-max-microamp = <2580000>; + }; + }; + }; + }; + mmc@12550000 { num-slots = <1>; supports-highspeed; -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
