+title: Zinitix BT4xx and BT5xx series touchscreen controller bindings
+
+description: The Zinitix BT4xx and BT5xx series of touchscreen controllers
+  are Korea-produced touchscreens with embedded microcontrollers. The
+  BT4xx series was produced 2010-2013 and the BT5xx series 2013-2014.

-Device tree bindings for Zinitx BT541 touchscreen controller
-
-Required properties:
-
- - compatible		: Should be "zinitix,bt541"
- - reg			: I2C address of the chip. Should be 0x20
- - interrupts		: Interrupt to which the chip is connected
-
-Optional properties:
-
- - vdd-supply		: Analog power supply regulator on VCCA pin
- - vddo-supply		: Digital power supply regulator on VDD pin
- - zinitix,mode		: Mode of reporting touch points. Some modes may not work
-			  with a particular ts firmware for unknown reasons. Available
-			  modes are 1 and 2. Mode 2 is the default and preferred.
