This is problematic. How this should be handled?

If nothing else works, you can add two compat strings, for example: "qcom,ipq8064-sfpb-mutex", "syscon"; This way if we add an sfpb driver at some point, we can still use old dts files.

It looks like they share quite some code.. Mhh don't know they have some peculiar changes so unifying them would make more harm than good IMHO. > > Konrad > > arch/arm/boot/dts/qcom-ipq8064.dtsi | 18 ++++++++++++++++++ > > 1 file changed, 18 insertions(+) > > > > diff --git a/arch/arm/boot/dts/qcom-ipq8064.dtsi b/arch/arm/boot/dts/qcom-ipq8064.dtsi > > index b5aede3d7ccf..98527a7d885e 100644 > > --- a/arch/arm/boot/dts/qcom-ipq8064.dtsi > > +++ b/arch/arm/boot/dts/qcom-ipq8064.dtsi > > @@ -908,6 +908,11 @@ lcc: clock-controller@28000000 { > > #reset-cells = <1>; > > }; > > > > + sfpb_mutex_block: syscon@1200600 { > > + compatible = "syscon"; > > + reg = <0x01200600 0x100>; > > + }; > > + > > pcie0: pci@1b500000 { > > compatible = "qcom,pcie-ipq8064"; > > reg = <0x1b500000 0x1000 > > @@ -1332,4 +1337,17 @@ sdcc3: mmc@12180000 { > > }; > > }; > > }; > > + > > + sfpb_mutex: sfpb-mutex { > > + compatible = "qcom,sfpb-mutex"; > > + syscon = <&sfpb_mutex_block 4 4>; > > + > > + #hwlock-cells = <1>; > > + }; > > + > > + smem { > > + compatible = "qcom,smem"; > > + memory-region = <&smem>; > > + hwlocks = <&sfpb_mutex 3>; > > + }; > > };

This is problematic. How this should be handled? As usual - add specific compatible. Maybe I was not specific enough, but my commit was under compatible, not under device node, so it seems obvious. Just in case it is not obvious - you cannot have "syscon" compatible alone. Best regards, Krzysztof
