2018-03-24	watchdog: aspeed: Allow configuring for alternate boot	Milton Miller	1	-0/+4
	Allow the device tree to specify a watchdog to fallover to the alternate boot source. The aspeeed watchdog can set a latch directing flash chip select 0 to chip select 1, allowing boot from an alternate media if the watchdog is not reset in time. On the ast2400 bank 1 also goes to flash bank 1, while on the ast2500 the chip selects are swapped. Also clear the secondary boot bit during the machine restart operation. Otherwise, the system will switch to the alternate boot after every reboot, which is not desired.

2018-03-24	watchdog: Add Nuvoton NPCM watchdog driver	Joel Stanley	3	-0/+266
	The Nuvoton NPCM750 has a watchdog implemented as a single register inside the timer peripheral. This driver exposes that watchdog as a standard watchdog device with coarse timeout intervals, limited by the combination of prescaler and counter that is provided by the hardware. The calculation is taken from the Nuvoton vendor tree. The watchdog is left running if a bootloader had it going. The rate is the one specified in the device tree, or the default value (obtained from the datasheet). There is a pre-timeout IRQ that is wired up. This timeout always occurs 1024 clocks before the timeout.
