[PATCH v2 0/8] Add Samsung Galaxy S4 support

[Alexandre MINETTE via B4 Relay]

Add initial mainline support for the Samsung Galaxy S4, codenamed jflte.

This series adds the devicetree binding and board DTS, together with the
small driver and common DTS changes needed to boot the device with working
USB peripheral mode.

Tested on a Samsung Galaxy S4 GT-I9505. With this series the device boots
and supports UART, USB peripheral mode with USB networking, the front
notification LED and the physical buttons.
