Arnd Bergmann ec2e32ca66 watchdog: iop_wdt only builds for mach-iop13xx
All three iop variants we support in Linux (iop32x, iop33x and
iop13xx) seem to have support for the watchdog hardware, but this
driver fails to build for the first two of these because it
uses the IOP13XX_WDTCR_IB_RESET macro that is only defined for
iop13xx.

This clarifies the dependency in Kconfig to avoid randconfig
build errors. It is unlikely that anyone will ever miss support
for this driver on the ancient iop3xx platforms, so we don't
need to bother trying to fix it properly.

Xiubo Li a797700329 watchdog: imx2_wdt: convert to use regmap API.
This watchdog driver will be working on IMX2+, Vybrid, LS1, LS2+
platforms, and will be in different endianness mode in those SoCs:

SoCs         CPU endian mode      WDT endian mode
------------------------------------------------
IMX2+            LE                    LE
Vybird           LE                    LE
LS1              LE                    BE
LS2              LE                    LE

Other possible SoCs:
SoCs         CPU endian mode      WDT endian mode
------------------------------------------------
Soc1             BE                    BE
Soc2             BE                    LE

And also the watchdog's registers will be 32-bits for some versions,
and though it is 16-bits in IMX2+, Vybird and LS+.

Using the regmap APIs, could be more easy to support different
endianness and also more easy to support 32-bits version...

Ivan Khoronzhuk f48f3ceabf watchdog: davinci: change driver to use WDT core
To reduce code duplicate and increase code readability use WDT core
code to handle WDT interface.

Remove io_lock as the WDT core uses mutex to lock each wdt device.
Remove wdt_state as the WDT core tracks state with its own variable.

The watchdog_init_timeout() can read timeout value from timeout-sec
property if the passed value is out of bounds. The heartbeat is
initialized in next way. If heartbeat is not set thought module
parameter, try to read it's value from WDT node timeout-sec property.
If node has no one, use default value.

The heartbeat is hold in wdd->timeout by WDT core, so use it in
order to set timeout period.

Davinci WDT can't be stopped and once it's expired - it can be
rearmed only after hardware reset, that's why nowayout feature
is enforced.

The watchdog infrastructure in Dove is no different from that in

Rather than duplicating the same register bit masks for the RSTOUTn_MASK

driver itself.
