+Raydium WT030 touch controller
+
+Please add this description here: The Raydium Touch controller is connected to the

+ - reg : i2c slave address of the device.
+ - interrupt-parent : parent of interrupt.
+ - raydium,irq-gpio : irq gpio.
+ - raydium,reset-gpio : reset gpio.
+ - vdd_ana-supply : analog voltage power supply needed to power device.
+ - vcc_i2c-supply : i2c voltage power supply needed to power device.

+Optional property:
+ - raydium,max-num-touches : addr of ub-i2c.

+ - raydium,x_max : maximal x value of the panel.

- --- 7.1 header-y
+ --- 7.1 no-export-headers
- header-y specifies header files to be exported.
+ no-export-headers is essentially used by include/uapi/linux/Kbuild to
+ avoid exporting specific headers (e.g. kvm.h) on architectures that do
+ not support it. It should be avoided as much as possible.
- Example:
- #include/linux/Kbuild
- header-y += usb/
- header-y += aio_abi.h
-
- The convention is to list one file per line and
- preferably in alphabetic order.
-
- header-y also specifies which subdirectories to visit.
- A subdirectory is identified by a trailing '/' which
- can be seen in the example above for the usb subdirectory.
-
- Subdirectories are visited before their parent directories.
-
- --- 7.2 genhdr-y
-
- genhdr-y specifies generated files to be exported.
- Generated files are special as they need to be looked
- up in another directory when doing 'make O=...' builds.
-
- Example:
- #include/linux/Kbuild
- genhdr-y += version.h
-
- --- 7.3 destination-y
-
- When an architecture has a set of exported headers that needs to be
- exported to a different directory destination-y is used.
- destination-y specifies the destination directory for all exported
- headers in the file where it is present.
-
- Example:
- #arch/xtensa/platforms/s6105/include/platform/Kbuild
- destination-y := include/linux
-
- In the example above all exported headers in the Kbuild file
- will be located in the directory "include/linux" when exported.
