From: Konrad Dybcio <konrad.dybcio@xxxxxxxxxx> [ Upstream commit 6e115b75b43bd12d4061e53c8ff175e387783d8a ] The serial ports did not have their interconnect paths specified when they were first introduced. Fix that. Fixes: 5188049c9b36 ("arm64: dts: qcom: Add base SM8450 DTSI") Fixes: f5837418479a ("arm64: dts: qcom: sm8450: add uart20 node") Reported-by: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx> Suggested-by: Georgi Djakov <djakov@xxxxxxxxxx> Signed-off-by: Konrad Dybcio <konrad.dybcio@xxxxxxxxxx> Reviewed-by: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx> Tested-by: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx> Link: https://lore.kernel.org/r/20240116-topic-8450serial-v1-1-b685e6a5ad78@xxxxxxxxxx Signed-off-by: Bjorn Andersson <andersson@xxxxxxxxxx> Signed-off-by: Sasha Levin <sashal@xxxxxxxxxx> --- arch/arm64/boot/dts/qcom/sm8450.dtsi | 12 ++++++++++++ 1 file changed, 12 insertions(+) diff --git a/arch/arm64/boot/dts/qcom/sm8450.dtsi b/arch/arm64/boot/dts/qcom/sm8450.dtsi index 91d856e5b06b5..0fc25c6a481f7 100644 --- a/arch/arm64/boot/dts/qcom/sm8450.dtsi +++ b/arch/arm64/boot/dts/qcom/sm8450.dtsi @@ -1025,6 +1025,12 @@ uart20: serial@894000 { pinctrl-names = "default"; pinctrl-0 = <&qup_uart20_default>; interrupts = <GIC_SPI 587 IRQ_TYPE_LEVEL_HIGH>; + interconnects = <&clk_virt MASTER_QUP_CORE_2 QCOM_ICC_TAG_ALWAYS + &clk_virt SLAVE_QUP_CORE_2 QCOM_ICC_TAG_ALWAYS>, + <&gem_noc MASTER_APPSS_PROC QCOM_ICC_TAG_ALWAYS + &config_noc SLAVE_QUP_2 QCOM_ICC_TAG_ALWAYS>; + interconnect-names = "qup-core", + "qup-config"; status = "disabled"; }; @@ -1417,6 +1423,12 @@ uart7: serial@99c000 { pinctrl-names = "default"; pinctrl-0 = <&qup_uart7_tx>, <&qup_uart7_rx>; interrupts = <GIC_SPI 608 IRQ_TYPE_LEVEL_HIGH>; + interconnects = <&clk_virt MASTER_QUP_CORE_2 QCOM_ICC_TAG_ALWAYS + &clk_virt SLAVE_QUP_CORE_2 QCOM_ICC_TAG_ALWAYS>, + <&gem_noc MASTER_APPSS_PROC QCOM_ICC_TAG_ALWAYS + &config_noc SLAVE_QUP_2 QCOM_ICC_TAG_ALWAYS>; + interconnect-names = "qup-core", + "qup-config"; status = "disabled"; }; }; -- 2.43.0
