Subject[PATCH v2 1/3] input: touchscreen: ad7879: move header to platform_data directory
Date
The header file is used by the SPI and I2C variant of the driver.
Therefore, move it to a more generic place under platform_data.

Signed-off-by: Stefan Agner <stefan@agner.ch>

Changes since v1:
- Move to include/linux/platform_data/
