This patch series adds devicetree support for the Forlinx FETA40i-C SoM
and OKA40i-C carrier board/devboard.

The FETA40i-C is an "industrial/automotive" SoM by Forlinx.

SoM specs:
- SoC: R40 or A40i
- PMIC: AXP221S
- RAM: 1GiB/2GiB DDR3 (dual-rank)
- eMMC: 8GB,
- Mates with carrier board via four 80-pin connectors (AXK6F80337YG).

OKA40i-C is a carrier board by the same manufacturer for this SoM,
whose main purpose is as a development board with a variety of
peripherals:

- Power: DC5V barrel or USB OTG or 4.2V Lipo battery
- Video out: HDMI, TV out, LVDS
- WiFi+Bluetooth: RL-UM02WBS-8723BU-V1.2 (802.11 b/g/n, BT V2.1/3.0/4.0)
- Ethernet: 10/100Mbps
- Storage: µSD, fullsize SD, eMMC (on SoM), SATA
- USB: 3 x USB2.0 Host (2 via hub, 1 native), 1 x USB2.0 OTG (micro-B)
- UART: RS232, RS485, 4 3.3v uarts (of which 2 have RTS/CTS)
- Other I/O: SPI x2, TWI, SDIO header, GPIO header, JTAG header
- Mini PCIe slot with sim holder for WLAN modem
- Smart card holder
- RTC (RX8010SJ)
- Two user LEDs
- Three user buttons (via KeyADC).

Of the board features listed above, support for the following has *NOT*
been tested:
- TV out & LVDS
- SATA
- Smart cards
- KeyADC buttons (no support)

The series consists of five patches, with dependencies as follows:

* Patch 4 depends on patch 3;
* Patch 5 depends on patches 2&4.

The rest are independent, however patch 2 may refuse to apply
without patch 1.
