Like with adsp, I can't verify this information, but with this change modem is still starting up as expected: Tested-by: Luca Weiss <luca.weiss@fairphone.com> > > Cc: <stable@vger.kernel.org> > Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> > --- > arch/arm64/boot/dts/qcom/sm6350.dtsi | 2 +- > 1 file changed, 1 insertion(+), 1 deletion(-) > > diff --git a/arch/arm64/boot/dts/qcom/sm6350.dtsi b/arch/arm64/boot/dts/qcom/sm6350.dtsi > index 3df506c2745ea27f956ef7d7a4b5fbaf6285c428..64b9602c912c970b49f57e7f2b3d557c44717d38 100644 > --- a/arch/arm64/boot/dts/qcom/sm6350.dtsi > +++ b/arch/arm64/boot/dts/qcom/sm6350.dtsi > @@ -1503,7 +1503,7 @@ gpucc: clock-controller@3d90000 { > > mpss: remoteproc@4080000 { > compatible = "qcom,sm6350-mpss-pas"; > - reg = <0x0 0x04080000 0x0 0x4040>; > + reg = <0x0 0x04080000 0x0 0x10000>; > > interrupts-extended = <&intc GIC_SPI 136 IRQ_TYPE_EDGE_RISING>, > <&modem_smp2p_in 0 IRQ_TYPE_EDGE_RISING>,

The address space in MPSS/Modem PAS (Peripheral Authentication Service) remoteproc node should point to the QDSP PUB address space (QDSP6...SS_PUB) which has a length of 0x10000. Value of 0x4040 was copied from older DTS, but it grew since then. This should have no functional impact on Linux users, because PAS loader does not use this address space at all.
