These are used to notify the Always on Subsystem (AOSS) that a particular co-processor is up/down. AOSS uses this information to wait for the co-processors to suspend before starting its sleep sequence. These co-processors enter low-power modes independent to that of the application processor and the load state resources linked to them are expected to remain unaltered across system suspend/resume cycles. To achieve this behavior let's stop modeling them as power-domains and replace them with generic qmp_send interface instead. https://lore.kernel.org/lkml/20200913034603.GV3715@yoga/ Previous dicussion on dropping power-domain support from AOSS QMP driver Depends on: qmp_send: https://patchwork.kernel.org/project/linux-arm-msm/cover/1623237532-20829-1-git-send-email-sibis@codeaurora.org/ V3: * Misc. documentation fixes [patch 2]: - Reduce power-domain maxItems due to load_state pd removal - Combine compatibles where possible with the load_state pd removal - Fixup the qcom,qmp ref to phandle type V2: * load_state is currently broken on mainline so be safely dropped without side-effects. * Rebased on top of qmp_send v3 series. * Dropped R-b from Stephen and Rob on patch 3 due to the yaml conversion. * New patch [12] to drop unused aoss-qmp header. * Commit message update [patch 1] [Rob] * Reorder the series [Stephen] Sibi Sankar (13): dt-bindings: soc: qcom: aoss: Drop power-domain bindings dt-bindings: remoteproc: qcom: pas: Add QMP bindings dt-bindings: remoteproc: qcom: Add QMP bindings remoteproc: qcom: q6v5: Use qmp_send to update co-processor load state arm64: dts: qcom: sc7180: Use QMP binding to control load state arm64: dts: qcom: sc7280: Use QMP binding to control load state arm64: dts: qcom: sdm845: Use QMP binding to control load state arm64: dts: qcom: sm8150: Use QMP binding to control load state arm64: dts: qcom: sm8250: Use QMP binding to control load state arm64: dts: qcom: sm8350: Use QMP binding to control load state soc: qcom: aoss: Drop power domain support dt-bindings: msm/dp: Remove aoss-qmp header dt-bindings: soc: qcom: aoss: Delete unused power-domain definitions .../bindings/display/msm/dp-controller.yaml | 1 - .../devicetree/bindings/remoteproc/qcom,adsp.yaml | 62 ++++++------ .../devicetree/bindings/remoteproc/qcom,q6v5.txt | 7 +- .../devicetree/bindings/soc/qcom/qcom,aoss-qmp.txt | 16 +-- arch/arm64/boot/dts/qcom/sc7180.dtsi | 9 +- arch/arm64/boot/dts/qcom/sc7280.dtsi | 2 - arch/arm64/boot/dts/qcom/sdm845.dtsi | 8 +- arch/arm64/boot/dts/qcom/sm8150.dtsi | 28 +++--- arch/arm64/boot/dts/qcom/sm8250.dtsi | 22 ++--- arch/arm64/boot/dts/qcom/sm8350.dtsi | 30 +++--- drivers/remoteproc/qcom_q6v5.c | 56 ++++++++++- drivers/remoteproc/qcom_q6v5.h | 7 +- drivers/remoteproc/qcom_q6v5_adsp.c | 7 +- drivers/remoteproc/qcom_q6v5_mss.c | 44 ++------- drivers/remoteproc/qcom_q6v5_pas.c | 80 ++++----------- drivers/remoteproc/qcom_q6v5_wcss.c | 4 +- drivers/soc/qcom/qcom_aoss.c | 109 +-------------------- include/dt-bindings/power/qcom-aoss-qmp.h | 14 --- 18 files changed, 184 insertions(+), 322 deletions(-) delete mode 100644 include/dt-bindings/power/qcom-aoss-qmp.h
