There is an mainline OpenSBI user of this and setting status okay resolves the stall of Linux when probing peripherals at boot. Fixes: 56f37e391a62 ("riscv: dts: spacemit: add initial support for K3 SoC") Signed-off-by: E Shattow --- Follows a discussion changing the status at U-Boot mailing list: https://lore.kernel.org/u-boot/20261028184526.1887640-2-e@freeshell.de/ Moving the discussion to LKML as there are differences of opinion on whether this should be changed in Linux or let remain to downstream users changing this in firmware that requires it. The change is trivial to carry downstream in mainline U-Boot. --- arch/riscv/boot/dts/spacemit/k3.dtsi | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/arch/riscv/boot/dts/spacemit/k3.dtsi b/arch/riscv/boot/dts/spacemit/k3.dtsi index a5fb72e23dcf..4b3362b64e26 100644 --- a/arch/riscv/boot/dts/spacemit/k3.dtsi +++ b/arch/riscv/boot/dts/spacemit/k3.dtsi @@ -1452,7 +1452,7 @@ mimsic: interrupt-controller@f1000000 { msi-controller; riscv,hart-index-bits = <4>; riscv,num-ids = <511>; - status = "reserved"; + status = "okay"; }; maplic: interrupt-controller@f1800000 { @@ -1464,7 +1464,7 @@ maplic: interrupt-controller@f1800000 { riscv,children = <&saplic>; riscv,delegation = <&saplic 1 512>; riscv,num-sources = <512>; - status = "reserved"; + status = "okay"; }; aclint_mswi: interrupt-controller@f1810000 { base-commit: c339f4010dea8b0d754f84ace70cd1b089878ef8 -- 2.53.0 _______________________________________________ linux-riscv mailing list linux-riscv@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-riscv
