From: Mylène Josserand <mylene.josserand@free-electrons.com>
Add the Cypress TrueTouch Generation 5 touchscreen device tree bindings documentation. It can use I2C or SPI bus. This touchscreen can handle some defined zone that are designed and sent as button. To be able to customize the keycode sent, the "linux,code" property in a "button" sub-node can be used.
