This patch serie adds support for TS-4800 board. This board,
manufactured by Technologic Systems, is based on an IMX515.
The first stage bootloader, called TS-BOOTROM, enables the watchdog,
so a watchdog driver is required to prevent board from rebooting.
The current device tree is minimal but it allows to get a shell on the
board.
Changes in v2:
- Added a mfd driver to handle syscon registers
- The watchdog driver now uses the regmap (created by the mfd driver)
to access the feed register
- Remove watchdog's dependency on SOC_IMX51
