I am having problems with this patch.
Problem is "reset"command fails (for my board) with:

resetting ...
### ERROR ### Please RESET the board ###
I traced down problem to "drivers/sysreset/sysreset-uclass.c" requesting
"uclass_first_device(UCLASS_SYSRESET, &dev)", while
"drivers/reset/reset-mips.c"
defines:
static const struct udevice_id mtmips_reset_ids[] = {
{ .compatible = "mediatek,mtmips-reset" },
{ }
};
U_BOOT_DRIVER(mtmips_reset) = {
.name = "mtmips-reset",
.id = UCLASS_RESET,
... so UCLASS_SYSRESET list is empty.
What am I doing wrong?
TiA!

do you have the according node with compatible string
"mediatek,mtmips-reset" in your device-tree?
Yes, I do, but problem is elsewhere:
"reset" command looks for a UCLASS_SYSRESET while
drivers/reset/reset-mips.c
(implementing "mediatek,mtmips-reset") provides a UCLASS_RESET.
I know too little about u-boot internals to understand which one I
should "fix" (if any).
I just tested current mainline U-Boot (top-of-tree) on the GARDENA
board and the reset works just fine:
=> reset

I didn't check the details of this mail thread, so I can't really
comment on this. Your board is so similar to the GARDENA one (LinkIt)
that it should work there as well. Do you gave some differences in
your defconfig?
Thanks,
Stefan
