2017-12-19Input: hideep - fix compile error due to missing include fileAnthony Kim1-2/+1
gpiod_() API requires including "linux/gpio/consumer.h". Also, we are not using the legacy API nor the static board files descriptions, so no need to include gpio.h nor gpio/machine.h.

The HiDeep touchscreen device is a capacitive multi-touch controller mainly for multi-touch supported devices use. It use I2C interface for communication to IC and provide axis X, Y, Z locations for ten finger touch through input event interface to userspace. It support the Crimson and the Lime two type IC. They are different the number of channel supported and FW size. But the working protocol is same.
