Crashdump collection is enabled based on the DLOAD bit in the TCSR register. This bit is set during bootup and cleared during shutdown. During crash, dload bit is not cleared, due to which uboot starts crashdump collection. This patch series adds the support for crashdump collection. This series depends on the below patch set. https://lore.kernel.org/linux-arm-msm/20230201060319.20434-1-quic_devipriy@xxxxxxxxxxx/ Changes in V2: - rebased on linux-next/master - dropped co-developed by tag wherever applicable - V1 can be found at https://lore.kernel.org/linux-arm-kernel/20230113160012.14893-1-quic_poovendh@xxxxxxxxxxx/ Poovendhan Selvaraj (5): dt-bindings: scm: Add compatible for IPQ9574 arm64: dts: Add support for Crashdump collection on IPQ9574 firmware: scm: Modify only the DLOAD bit in TCSR register for download mode arm64: defconfig: Enable scm download mode config for IPQ9574 SoC. dt-bindings: tcsr: Add compatible for IPQ9574 .../bindings/firmware/qcom,scm.yaml | 1 + .../devicetree/bindings/mfd/qcom,tcsr.yaml | 1 + arch/arm64/boot/dts/qcom/ipq9574.dtsi | 26 ++++++++++++++++++- arch/arm64/configs/defconfig | 1 + drivers/firmware/qcom_scm.c | 12 ++++++--- 5 files changed, 36 insertions(+), 5 deletions(-) base-commit: 80bd9028fecadae4e8e3a278cd32d74badc2a6e0 -- 2.17.1
