source code size, improve readability, and reduce the likelyhood of bugs.
Other improvements as listed below.The conversion was done automatically with coccinelle using the
following semantic patches. The semantic patches and the scripts
used to generate this commit log are available at
https://github.com/groeck/coccinelle-patches- Drop assignments to otherwise unused variables
- Drop unnecessary braces around conditional return statements
- Drop empty remove function
- Use devm_add_action_or_reset() for calls to clk_disable_unprepare
- Use devm_watchdog_register_driver() to register watchdog device
- Replace shutdown function with call to watchdog_stop_on_reboot()Signed-off-by: Guenter Roeck

When the driver is built on 32 bit architectures during compile test,
the linker complains about "__udivdi3" being undefined. We have to use
do_div macro instead of the division operator when dividing u64 value.Signed-off-by: Marek Behún

This adds support for the CPU watchdog found on Marvell Armada 37xx
SoCs.There are 4 counters which can be set as CPU watchdog counters.
This driver uses the second counter (ID 1, counting from 0) as watchdog
counter, and first counter (ID 0) to implement pinging on the second
counter without the need to disable it.Since counters IDs 2 and 3 are enabled already before even U-Boot
starts, this driver does not use them at all, for example by adding a
device tree property for counter selection.Signed-off-by: Marek Behún
