[PATCH 0/2] iNet U70B Rev 01 Tablet Support

[Samuel Holland]

This series adds a binding and devicetree for yet another A33-based
tablet board. The devicetree currently fails validation because I have
no idea what compatible string to use for the DPI panel. Neither the
hardware nor the software provide any clues about a manufacturer or
model -- the driver used by the vendor Android is called "default_lcd".

[PATCH 2/2] ARM: dts: sun8i: A33: Add iNet U70B Rev 01

[Samuel Holland]

This is a white-label 7" tablet board based on the A33 SoC. It features
a generic 1024x600 DPI panel, raw NAND for storage, and a Realtek 8723CS
Wi-Fi/Bluetooth chip.

Can you drop the node until this is figured out? Otherwise DT file looks fine.
