新年好！最近用bq3060调试，快要发货了，但是bq3060调试不通，请帮忙看看。
读取的值都不正常，比如：cat sys/class/power_supply/bq3060-battery/voltage_now ， 读取的值为-6
打印的log是 [ 45.170688] bq3060-battery 0-0016: error reading voltage
对应的代码是：
static int bq3060_battery_voltage(struct bq3060_device_info *di)
{
int ret;
u8 buf[2];
int volt = 0;
ret = bq3060_read(di->client,BQ3060_REG_VOLT,buf,2);
if (ret<0) {
dev_err(di->dev, "error reading voltage\n");
return ret;
}
volt = get_unaligned_le16(buf);
volt = volt;
DBG("Enter:%s %d--volt = %d\n",__FUNCTION__,__LINE__,volt);
return volt;
}
读取的函数为：bq3060_read()
static int bq3060_read(struct i2c_client *client, u8 reg, u8 buf[], unsigned len)
{
struct i2c_adapter *adap=client->adapter;
struct i2c_msg msgs[2];
int ret;
char reg_buf = reg;
msgs[0].addr = client->addr; // slave addr
msgs[0].flags = client->flags;
msgs[0].len = 1; // command code is 8bit
msgs[0].buf = ®_buf; // command code
msgs[0].scl_rate = bq3060_SPEED;
msgs[1].addr = client->addr;
msgs[1].flags = client->flags | I2C_M_RD;
msgs[1].len = len;
msgs[1].buf = (char *)buf;
msgs[1].scl_rate = bq3060_SPEED;
ret = i2c_transfer(adap, msgs, 2);
return (ret == 2)? len : ret;
}
硬件平台是s5pv210, 其支持smbus. 单独用EV2300测试过，可以通过。
sda, scl, gnd 分别接到了主控器的i2c0上。
完整的驱动代码见附件，请帮忙看看，多谢！
