From: Ludovic Barre <ludovic.barre@xxxxxx>
This patch series updates stm32 watchdog driver on:
-use devm_watchdog_register_device
-Guenter's recommendation about return value:
set_timeout return 0 on succes, -EINVAL for "parameter out of range"
and -EIO for "could not write value to the watchdog".
Set of reload and prescaler registers are stay in start function,
because the stm32 watchdog must be enabled to write these registers.
-adds dynamic prescaler support

watchdog: stm32: update to devm_watchdog_register_device
