It also only bringing up the 1st core in SoCs with a dual-core SCP, e.g. MT8195. This series support to bring-up the 2nd core of the dual-core SCP. v10 -> v11: 1. rewrite patchset 5 to probe single-core SCP with the cluster list 2. Also in patchset 5, move the pointer of mtk_scp object from the platform data property to the driver data property 3. move the appearance of mtk_scp cluster property to patcheset 7 v9 -> v10: 1. move the global mtk_scp list into the platform device driver data structure 2. remove an unnecessary if() condition v8 -> v9: 1. initialize l1tcm_size/l1tcm_phys at patchset 05/11 2. rewrite patchset 06/11 to unify the flow and remove hacks v7 -> v8: 1. update the node name of mt8192 asurada SCP rpmsg subnode 2. squash register definitions into driver patches 3. initialize local variables on the declaration at patch v8 06/11 v6 -> v7: 1. merge the mtk_scp_cluster struct into the mtk_scp structure at the "Probe multi-core SCP" patch v5 -> v6: 1. move the mtk_scp_of_regs structure from mtk_common.h to mtk_scp.c 2. rename the SCP core 0 label from 'scp' to 'scp_c0' v4 -> v5: 1. move resource release actions to the platform driver remove operation 2. fix dual-core watchdog handling v3 -> v4: 1. change the representation of dual-core SCP in dts file and update SCP yaml 2. rewrite SCP driver to reflect the change of dts node 3. drop 'remove redundant call of rproc_boot for SCP' in v3 for further investigation v2 -> v3: 1. change the representation of dual-core SCP in dts file and update SCP yaml 2. rewrite SCP driver to reflect the change of dts node 3. add SCP core 1 node to mt8195.dtsi 4. remove redundant call of rproc_boot for SCP 5. refine IPI error message v1 -> v2: 1. update dt-binding property description 2. remove kconfig for scp dual driver 3. merge mtk_scp_dual.c and mtk_scp_subdev.c to mtk_scp.c Tinghan Shen (11): dt-bindings: remoteproc: mediatek: Improve the rpmsg subnode definition arm64: dts: mediatek: Update the node name of SCP rpmsg subnode dt-bindings: remoteproc: mediatek: Support MT8195 dual-core SCP remoteproc: mediatek: Add MT8195 SCP core 1 operations remoteproc: mediatek: Introduce cluster on single-core SCP remoteproc: mediatek: Probe multi-core SCP remoteproc: mediatek: Control SCP core 1 by rproc subdevice remoteproc: mediatek: Setup MT8195 SCP core 1 SRAM offset remoteproc: mediatek: Handle MT8195 SCP core 1 watchdog timeout remoteproc: mediatek: Refine ipi handler error message arm64: dts: mediatek: mt8195: Add SCP 2nd core .../bindings/remoteproc/mtk,scp.yaml | 176 +++++++- .../arm64/boot/dts/mediatek/mt8183-kukui.dtsi | 2 +- .../boot/dts/mediatek/mt8192-asurada.dtsi | 2 +- .../boot/dts/mediatek/mt8195-cherry.dtsi | 6 +- arch/arm64/boot/dts/mediatek/mt8195.dtsi | 32 +- drivers/remoteproc/mtk_common.h | 32 ++ drivers/remoteproc/mtk_scp.c | 420 ++++++++++++++++-- 7 files changed, 595 insertions(+), 75 deletions(-)
