Add the New Device to Your Board file • For our driver, we added the new device into our “board-8660.c file” – The Kionix device needed to have “power on” and “power off” functions • We leveraged the reference sensor “power on” and off code from board-7x30.c and made the following modifications – One regulator needed to be turned on – Voltage needed to be set to 2.85v – Neede a New regulator API vs. the code in the 7x30 file
Add the New Device to Your Board file – Created an i2c_board_info structure based on data from the datasheet and board schematic • I2c address is 0x18 – from datasheet • IRQ is tied to GPIO pin 57 – from schematic – Added a new “i2c_board_info” structure to the list of devices to initialize at start up • register_i2c_devices() – Now you are ready to boot the kernel and you should see KXSD9 initialization messages
