Hi, This is Mediatek MT8173 Command Queue(CMDQ) driver. The CMDQ is used to help write registers with critical time limitation, such as updating display configuration during the vblank. It controls Global Command Engine (GCE) hardware to achieve this requirement. These patches have a build dependency on top of v4.10-rc1. Changes since v18: - add "select MAILBOX" into CMDQ helper - remove power saving part to prevent a potential bug Best regards, HS Liao HS Liao (4): dt-bindings: soc: Add documentation for the MediaTek GCE unit mailbox: mediatek: Add Mediatek CMDQ driver arm64: dts: mt8173: Add GCE node soc: mediatek: Add Mediatek CMDQ helper .../devicetree/bindings/mailbox/mtk-gce.txt | 43 ++ arch/arm64/boot/dts/mediatek/mt8173.dtsi | 10 + drivers/mailbox/Kconfig | 10 + drivers/mailbox/Makefile | 2 + drivers/mailbox/mtk-cmdq-mailbox.c | 596 +++++++++++++++++++++ drivers/soc/mediatek/Kconfig | 12 + drivers/soc/mediatek/Makefile | 1 + drivers/soc/mediatek/mtk-cmdq-helper.c | 310 +++++++++++ include/linux/mailbox/mtk-cmdq-mailbox.h | 75 +++ include/linux/soc/mediatek/mtk-cmdq.h | 174 ++++++ 10 files changed, 1233 insertions(+) create mode 100644 Documentation/devicetree/bindings/mailbox/mtk-gce.txt create mode 100644 drivers/mailbox/mtk-cmdq-mailbox.c create mode 100644 drivers/soc/mediatek/mtk-cmdq-helper.c create mode 100644 include/linux/mailbox/mtk-cmdq-mailbox.h create mode 100644 include/linux/soc/mediatek/mtk-cmdq.h -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
