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