MS5611-01BA03 Barometric Pressure Sensor Driver

MS5611-01BA03 Barometric Pressure Sensor, with statinless steel cap.

Building the source

1. Clone driver code

git clone https://github.com/Sarlor/ms5611-driver.git
cd ms5611-driver/src

2. Edit Makefile file, set the correct kernel directory 'KERN_DIR'

vim Makefile

3. Copy the driver files to the 'hwmon' directory

make cp

4. Add board-level support code to the appropriate place

vim arch/arm/plat-s5p4418/realarm/device.c

#if defined(CONFIG_SENSORS_MS561101BA) || defined(CONFIG_SENSORS_MS561101BA_MODULE)
#include <linux/i2c.h>

/* CODEC */
static struct i2c_board_info __initdata ms561101ba_i2c_bdi = {
	.type   = "ms561101ba",
	.addr   = 0x77
};
#endif

#if defined(CONFIG_SENSORS_MS561101BA) || defined(CONFIG_SENSORS_MS561101BA_MODULE)
	printk("plat: add pressure MS5611-01BA03\n");
	i2c_register_board_info(1, &ms561101ba_i2c_bdi, 1);
#endif

5. Modify the kernel configuration file for ms5611, and add the code to the appropriate place

vim drivers/hwmon/Kconfig

config SENSORS_MS561101BA
	tristate "MS5611-01BA03 Barometric Pressure Sensor"
        depends on I2C
        default n
        help
		Say Y here to enable the pressure sensor.

                If unsure, say N.

6. Edit Makefile for add ms5611 driver module

vim drivers/hwmon/Makefile

obj-$(CONFIG_SENSORS_MS561101BA)        += ms561101ba.o

7. Configure the kernel for required submodule, then save config

make menuconfig
