Hi Every One

 

i have a porting question as tittle said...

1. I use the imx6q system board to develop with android version is 4.4.3 , linux kernel is 3.10.53

2. recently i want to porting the MPU6050 driver code into my system board, but meet the driver code is not support linux kernel device tree structure

therefore, try to modified driver code to match new kernel version device tree structure...but after test...i still can not  to launch the MPU6050 sensor function successfully, the log message as below... , therefore, i want to ask whether any driver patch could reference to modified or any other about MPU6050 driver code device tree information... thx

 

attachment file is my driver code so far....

and below is my dts structure and log

 

imx6q.dts (setting the mpu6050 device node)

 

&i2c3 {

 

 

  clock-frequency = <400000>;

  pinctrl-names = "default";

  pinctrl-0 = <&pinctrl_i2c3_2>;

  status = "okay";

 

  mpu6050@69{

  compatible = "inv, mpu-6050";

  reg = <0x69>;

  interrupt-parent = <&gpio7>;

  interrupts = <13 2>;

  pwr-gpios = <&gpio6 7 0>;   /* active high: */

  int-gpios = <&gpio7 13 0>;   /* active high: */

  };

 

};

 

mach-imx6q.c (in order to turn on the mpu power)

 

 

static void __init imx6q_mpu_init(void){

  pr_warn("!!start mpu Power gpio\n");

  struct device_node *np = NULL;

  int ret, pwr_gpio;

  np = of_find_node_by_name(NULL, "mpu6050");

  if (!np)

  return;

printk("---------------start mpu power gpio-------------\n");

  pwr_gpio = of_get_named_gpio(np, "pwr-gpios", 0);

  if (gpio_is_valid(pwr_gpio)) {

  ret = gpio_request_one(pwr_gpio, GPIOF_OUT_INIT_LOW,

  "mpu Power On");

  pr_warn("!!request mpu Power gpio\n");

  if (ret)

  pr_warn("failed to request mpu Power On gpio\n");

  }

  msleep(5);

  gpio_set_value(pwr_gpio, 1);

  gpio_free(pwr_gpio);

  printk("---------------end mpu power gpio-------------\n");

 

 

}

Hello Victor,

You can get a Linux driver from Invensense they distribute a lot of drivers for different platforms and Linux Kernels, I recommend you to contact them

Here is a link;

Login | Developers

Or you can use the I2CTools to get the device conected and then you can find the device under /dev/i2c


Have a great day,
Jaime
