#1275487 — [PATCH v4 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 v4:
 - syscon: rewrite DT property reading to be clearer
 - watchdog: made fixes suggested by Guenter (now uses
   watchdog_init_timeout, u32 instead of u16, fixed error checking in
   probe, cleaned set_timeout)

Changes in v3:
 - Rebased on v4.3
 - Changed vendor prefix from "ts" to "technologic"
 - Added a DT option to generic syscon driver to allow regmap configuration
 - Dropped custom mfd driver, use generic syscon driver instead.

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: syscon: add a DT property to set value width
  watchdog: ts4800: add driver for TS-4800 watchdog
  ARM: imx_v6_v7_defconfig: add TS-4800 watchdog
  ARM: dts: TS-4800: add basic device tree

#1275488 — [PATCH v4 4/5] ARM: imx_v6_v7_defconfig: add TS-4800 watchdog

The TS-4800, based on an IMX.515, needs its watchdog support in order to
work.
