The Point of View protab2-ips9 is a tablet with a 9" ips 1024x768 lcd screen, microsd slot, headphones, mini hdmi, mini usb b and power barrel connectors. It uses a rtl8188cus usb wifi chip and a RDA 5875Y bluetooth chip attached to uart2. It has a bma250 accelerometer attached to i2c1 addr 0x18. It has a pixcir,pixcir_tangoc compatible touchscreen attached to i2c2 addr 0x5c. This is not enabled in this dts, because this variant of the pixcir_tangoc has separate wakeup and enable pins both of which need to be driven low before the touchscreen will work. Before we can enable this the pixcir driver and devicetree-bindings need to be extended to support these pins.
