[PATCH v4 0/2] ARM: sun5i: Add DT for HSG H702 tablet board

[Chen-Yu Tsai]

Hi,

This is v4 of the HSG H702 tablet support patch. I've split the original
patch into 2, one for the common 5V regulator, and the other for the
tablet.


Changes since v3
  - Move fixed regulator to common regulators in separate patch.
  - Use said common regulator for usb1-vbus. 
  - Slightly changed commit title

Changes since v2:
  - Dual license under GPL/X11.
  - Use extra fixed regulator for usb1-vbus.

[PATCH v4 1/2] ARM: dts: sunxi: Add fixed 5V regulator

[Chen-Yu Tsai]

Most if not all boards we've seen have a fixed 5V regulator, which is
the main power supply and/or fixed output of the PMIC.

Add this one to the common regulators DTSI.

[PATCH v4 2/2] ARM: dts: sun5i: Add DT for HSG H702 tablet board

[Chen-Yu Tsai]

This is a Q8 format 7 inch tablet with an Allwinner A13 SoC.
It has 512MB DRAM, 4GB NAND flash, an accelerometer, camera,
RTL8188-based WiFi, and micro SD slot for external storage.

It is likely made by a subsidiary of Hanns.G (Hannstar).
