  /**
   * struct i2chid_platform_data - used by hid over i2c implementation.
   * @hid_descriptor_address: i2c register where the HID descriptor is stored.

   * @supplies: regulators for powering on the device.

   * @post_power_delay_ms: delay after powering on before device is usable.

   *
   * Note that it is the responsibility of the platform driver (or the acpi 5.0

   * driver, or the flattened device tree) to setup the irq related to the gpio in
   * the struct i2c_board_info.

   * The platform driver should also setup the gpio according to the device:
   *
   * A typical example is the following:
   *	irq = gpio_to_irq(intr_gpio);
   *	hkdk4412_i2c_devs5[0].irq = irq; // store the irq in i2c_board_info
   *	gpio_request(intr_gpio, "elan-irq");
   *	s3c_gpio_setpull(intr_gpio, S3C_GPIO_PULL_UP);
