Subject: [PATCH v2 0/5] Add board support for TS-4800

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

Damien Riegel (5):
  of: add vendor prefix for Technologic Systems
  mfd: ts4800-syscon: add driver for TS-4800 syscon
  watchdog: ts4800: add driver for TS-4800 watchdog
  ARM: imx_v6_v7_defconfig: add TS-4800 watchdog and syscon
  ARM: dts: TS-4800: add basic device tree
