-/* Application note:
- *
- * The driver supports 4 operations: open(), close(), ioctl(), read()
- * The device name is /dev/envctrl.
- * Below is sample usage:
- *
- * fd = open("/dev/envtrl", O_RDONLY);
- * if (ioctl(fd, ENVCTRL_READ_SHUTDOWN_TEMPERATURE, 0) < 0)
- * printf("error\n");
- * ret = read(fd, buf, 10);
- * close(fd);
- *
- * Notice in the case of cpu voltage and temperature, the default is
- * cpu0. If we need to know the info of cpu1, cpu2, cpu3, we need to
- * pass in cpu number in ioctl() last parameter. For example, to
- * get the voltage of cpu2:
- *
- * ioctlbuf[0] = 2;
- * if (ioctl(fd, ENVCTRL_READ_CPU_VOLTAGE, ioctlbuf) < 0)
- * printf("error\n");
- * ret = read(fd, buf, 10);
- *
- * All the return values are in ascii. So check read return value
- * and do appropriate conversions in your application.
