Hi Olof and Arnd, Please find below the commit for the MediaTek SoC drivers. The most important changes are the inclusion of two new drivers. Devapc is an TrustZone interface found on the mobile phone chips to identify malicious accesses from bus controllers. Apart from that you can find a new power domain driver. We have the old scpsys driver for quite some time around, But it has some limitations, that we could only overcome with a brand new driver with a new binding. Right now these new driver supports mt8192 and mt8183 but the plan is, to move all SoCs to the new driver model and later on retire the old driver. Please beware that I had to create a stable branch to share some include files for the driver between the dts64 and this branch. Regards, Matthias --- The following changes since commit 3650b228f83adda7e5ee532e2b90429c03f7b9ec: Linux 5.10-rc1 (2020-10-25 15:14:11 -0700) are available in the Git repository at: https://git.kernel.org/pub/scm/linux/kernel/git/matthias.bgg/linux.git/ tags/v5.10-next-soc for you to fetch changes up to cc6576029aedc79ce87b9fcb22cbd396d47f2852: soc: mediatek: mmsys: Use devm_platform_ioremap_resource() (2020-11-28 00:37:12 +0100) ---------------------------------------------------------------- power-domains: - add support for new power domain driver. - add support for mt8183 and mt8192 devapc: - add support for the devapc device found on mt6779 to identify of malicious bus accesses from a controller to a device mmsys: - move DDP routing IDs into the driver cmdq: - drop timeout handler support as not usefull scpsys: - print warning on theoretical error ---------------------------------------------------------------- Chun-Kuang Hu (1): soc / drm: mediatek: cmdq: Remove timeout handler in helper function Enric Balletbo i Serra (5): mfd: syscon: Add syscon_regmap_lookup_by_phandle_optional() function. dt-bindings: power: Add bindings for the Mediatek SCPSYS power domains controller dt-bindings: power: Add MT8183 power domains soc: mediatek: Add MediaTek SCPSYS power domains soc: mediatek: mmsys: Use devm_platform_ioremap_resource() Matthias Brugger (10): MAINTAINERS: change mediatek wiki page Merge tag 'ib-mfd-mediatek-v5.11' into HEAD Merge tag 'v5.10-next-pm-domains-stable' into HEAD soc: mediatek: pm-domains: Add bus protection protocol soc: mediatek: pm_domains: Make bus protection generic soc: mediatek: pm-domains: Add SMI block as bus protection block soc: mediatek: pm-domains: Add extra sram control soc: mediatek: pm-domains: Add subsystem clocks soc: mediatek: pm-domains: Allow bus protection to ignore clear ack soc: mediatek: pm-domains: Add support for mt8183 Neal Liu (2): dt-bindings: devapc: add bindings for mtk-devapc soc: mediatek: add mt6779 devapc driver Nicolas Boichat (1): soc: mediatek: Check if power domains can be powered on at boot time Weiyi Lu (3): dt-bindings: power: Add MT8192 power domains soc: mediatek: pm-domains: Add default power off flag soc: mediatek: pm-domains: Add support for mt8192 Yongqiang Niu (1): soc / drm: mediatek: Move DDP component defines into mtk-mmsys.h .../bindings/power/mediatek,power-controller.yaml | 293 ++++++++++ .../devicetree/bindings/soc/mediatek/devapc.yaml | 58 ++ MAINTAINERS | 2 +- drivers/gpu/drm/mediatek/mtk_drm_crtc.c | 3 +- drivers/gpu/drm/mediatek/mtk_drm_ddp_comp.h | 34 +- drivers/mfd/syscon.c | 18 + drivers/soc/mediatek/Kconfig | 21 + drivers/soc/mediatek/Makefile | 2 + drivers/soc/mediatek/mt8173-pm-domains.h | 94 ++++ drivers/soc/mediatek/mt8183-pm-domains.h | 221 ++++++++ drivers/soc/mediatek/mt8192-pm-domains.h | 292 ++++++++++ drivers/soc/mediatek/mtk-cmdq-helper.c | 41 +- drivers/soc/mediatek/mtk-devapc.c | 308 +++++++++++ drivers/soc/mediatek/mtk-infracfg.c | 5 - drivers/soc/mediatek/mtk-mmsys.c | 11 +- drivers/soc/mediatek/mtk-pm-domains.c | 614 +++++++++++++++++++++ drivers/soc/mediatek/mtk-pm-domains.h | 102 ++++ drivers/soc/mediatek/mtk-scpsys.c | 5 +- include/dt-bindings/power/mt8183-power.h | 26 + include/dt-bindings/power/mt8192-power.h | 32 ++ include/linux/mfd/syscon.h | 11 + include/linux/soc/mediatek/infracfg.h | 107 ++++ include/linux/soc/mediatek/mtk-cmdq.h | 10 +- include/linux/soc/mediatek/mtk-mmsys.h | 33 ++ 24 files changed, 2243 insertions(+), 100 deletions(-) create mode 100644 Documentation/devicetree/bindings/power/mediatek,power-controller.yaml create mode 100644 Documentation/devicetree/bindings/soc/mediatek/devapc.yaml create mode 100644 drivers/soc/mediatek/mt8173-pm-domains.h create mode 100644 drivers/soc/mediatek/mt8183-pm-domains.h create mode 100644 drivers/soc/mediatek/mt8192-pm-domains.h create mode 100644 drivers/soc/mediatek/mtk-devapc.c create mode 100644 drivers/soc/mediatek/mtk-pm-domains.c create mode 100644 drivers/soc/mediatek/mtk-pm-domains.h create mode 100644 include/dt-bindings/power/mt8183-power.h create mode 100644 include/dt-bindings/power/mt8192-power.h
