[PATCH linux dev-4.13] ARM: configs: aspeed: Add watchdog sysfs

[PATCH linux dev-4.13] ARM: configs: aspeed: Add watchdog sysfs

[Eddie James]

This kernel config adds sysfs entries for watchdog devices. This is
needed in order to access the bootstatus sysfs file that will indicate
whether or not the BMC has tripped the watchdog and subsequently
switched sides.

When you update a defconfig you must follow these steps:

make aspeed_g5_defconfig

enable the options you require

make savedefconig
cp aspeed_g5_defconfig arc/arm/boot/config/

And create your commit based on that.

I have done this for you in this case and applied the result to dev-4.13.

Cheers,

Joel
