This offset only works for some SoCs like SDM845 for which driver support was initially added. But the later SoCs use different register stride that vary between the banks with holes in-between. So it is not possible to use a single register stride for accessing the CSRs of each bank. By doing so could result in a crash with the current drivers. So far this crash is not reported since EDAC_QCOM driver is not enabled in ARM64 defconfig and no one tested the driver extensively by triggering the EDAC IRQ (that's where each bank CSRs are accessed). For fixing this issue, let's obtain the base address of each LLCC bank from devicetree and get rid of the fixed stride. This series affects multiple platforms but I have only tested this on SM8250, SM8450, and SM6350. Testing on other platforms is welcomed. Thanks, Mani Changes in v3: * Brought back reg-names property for compatibility (Krzysztof) * Removed Fixes tag and stable list as backporting the drivers/binding/dts patches alone would break (Krzysztof) * Fixed the uninitialized variable issue (Kbot) * Added a patch to make use of driver supplied polling interval (Luca) * Added a patch for module autoloading (Andrew) * Didn't collect Review tags from Sai as the dts patches were changed. Changes in v2: * Removed reg-names property and used index of reg property to parse LLCC bank base address (Bjorn) * Collected Ack from Sai for binding * Added a new patch for polling mode (Luca) * Renamed subject of patches targeting SC7180 and SM6350 Manivannan Sadhasivam (15): dt-bindings: arm: msm: Update the maintainers for LLCC dt-bindings: arm: msm: Fix register regions used for LLCC banks arm64: dts: qcom: sdm845: Fix the base addresses of LLCC banks arm64: dts: qcom: sc7180: Fix the base addresses of LLCC banks arm64: dts: qcom: sc7280: Fix the base addresses of LLCC banks arm64: dts: qcom: sc8280xp: Fix the base addresses of LLCC banks arm64: dts: qcom: sm8150: Fix the base addresses of LLCC banks arm64: dts: qcom: sm8250: Fix the base addresses of LLCC banks arm64: dts: qcom: sm8350: Fix the base addresses of LLCC banks arm64: dts: qcom: sm8450: Fix the base addresses of LLCC banks arm64: dts: qcom: sm6350: Fix the base addresses of LLCC banks EDAC/device: Make use of poll_msec value in edac_device_ctl_info struct EDAC/qcom: Add platform_device_id table for module autoloading qcom: llcc/edac: Fix the base address used for accessing LLCC banks qcom: llcc/edac: Support polling mode for ECC handling .../bindings/arm/msm/qcom,llcc.yaml | 128 ++++++++++++++++-- arch/arm64/boot/dts/qcom/sc7180.dtsi | 2 +- arch/arm64/boot/dts/qcom/sc7280.dtsi | 5 +- arch/arm64/boot/dts/qcom/sc8280xp.dtsi | 10 +- arch/arm64/boot/dts/qcom/sdm845.dtsi | 7 +- arch/arm64/boot/dts/qcom/sm6350.dtsi | 2 +- arch/arm64/boot/dts/qcom/sm8150.dtsi | 7 +- arch/arm64/boot/dts/qcom/sm8250.dtsi | 7 +- arch/arm64/boot/dts/qcom/sm8350.dtsi | 7 +- arch/arm64/boot/dts/qcom/sm8450.dtsi | 7 +- drivers/edac/edac_device.c | 2 +- drivers/edac/qcom_edac.c | 58 +++++--- drivers/soc/qcom/llcc-qcom.c | 85 ++++++------ include/linux/soc/qcom/llcc-qcom.h | 6 +- 14 files changed, 241 insertions(+), 92 deletions(-)
