18 * The driver supports 4 operations: open(), close(), ioctl(), read()

20 * Below is sample usage:
21 *
22 * fd = open("/dev/envtrl", O_RDONLY);

27 *
28 * Notice in the case of cpu voltage and temperature, the default is
29 * cpu0. If we need to know the info of cpu1, cpu2, cpu3, we need to
30 * pass in cpu number in ioctl() last parameter. For example, to
31 * get the voltage of cpu2:
32 *
33 * ioctlbuf[0] = 2;
34 * if (ioctl(fd, ENVCTRL_READ_CPU_VOLTAGE, ioctlbuf) < 0)

38 * All the return values are in ascii. So check read return value
39 * and do appropriate conversions in your application.
