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.

+* HiDeep Finger and Stylus touchscreen controller
+
+Required properties:
+- compatible : must be "hideep,hideep_ts".
See my reply on previous version.
quoted hunk
+- reg : I2C slave address, (e.g. 0x6C).
+- interrupt-parent : Interrupt controller to which the chip is connected.
+- interrupts : Interrupt to which the chip is connected.
+
+Optional properties:
+- vdd-supply : It is the controller supply for controlling
+ main voltage(3.3V) through the regulator.
+- vid-supply : It is the controller supply for controlling
+ IO voltage(1.8V) through the regulator.
+- irq-gpios : Define for interrupt gpio pin.
+ It is to use for set interrupt type.
As mentioned in the last version, use "interrupts".
quoted hunk
+- reset-gpios : Define for reset gpio pin.
+ It is to use for reset IC.
+- hideep,max_coords : Max value for axis X, Y, W, Z.
