I am having problems with this patch.
Problem is "reset"command fails (for my board) with:
=> reset 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! Mauro
do you have the according node with compatible string "mediatek,mtmips-reset" in your device-tree?
I have the standard mt7628a.dtsi contents:
... palmbus@10000000 { compatible = "palmbus", "simple-bus"; reg = <0x10000000 0x200000>; ranges = <0x0 0x10000000 0x1FFFFF>; ... rstctrl: rstctrl@0x34 { reg = <0x34 0x4>; compatible = "mediatek,mtmips-reset"; #reset-cells = <1>; }; ...
I tried adding the "old-style": ... resetc: reset-controller { compatible = "ralink,rt2880-reset"; #reset-cells = <1>; }; ... but, apparently, it makes no difference.
Shouldn't that be enough?
