[PATCH v9 0/3] Add board support for TS-4800

From: Damien Riegel
Date: Fri Dec 11 2015 - 12:08:58 EST

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. It is
handled in a separate patchset.

The current device tree is minimal but it allows to get a shell on the

Changes in v9:
- Changed dts file license to X11/GPL
- Reordered i2c2 node to be alphabetically sorted
- Dropped container node in iomuxc

Changes in v8:
- Split the serie into two parts, watchdog and dts, because there are
no build dependencies between the two, and the syscon patch has been
separately applied in Lee Jones' tree.
- As a consequence, I dropped the patch which enabled the watchdog in
imx_v6_v7_defconfig to ease the integration.

Changes in v7:
- syscon: change bus-width DT property to reg-io-width
- watchdog: add dependency on HAS_IOMEM (spotted by a 0-day build)

Changes in v6:
- vendor prefix: reorder to sort alphabetically (wrong order since v3)
- split commit adding device tree into two patches: one for the doc, one for
the bindings

Changes in v5:
- watchdog: changed iteration stop condition in set_timeout to be less
error prone

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
