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 v4.9-rc1. Changes since v14: - split driver into mtk-cmdq-mailbox and mtk-cmdq-helper - split cmdq_task into cmdq_pkt for client and cmdq_task for controller - remove mailbox_controller.h from mtk-cmdq.h - replace msleep() by schedule() - replace irq_of_parse_and_map() by platform_get_irq() - remove .owner = THIS_MODULE - rebase to Linux v4.9-rc1 Best regards, HS Liao HS Liao (4): dt-bindings: soc: Add documentation for the MediaTek GCE unit CMDQ: Mediatek CMDQ driver arm64: dts: mt8173: Add GCE node CMDQ: save energy .../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 | 634 +++++++++++++++++++++ drivers/soc/mediatek/Kconfig | 11 + drivers/soc/mediatek/Makefile | 1 + drivers/soc/mediatek/mtk-cmdq-helper.c | 310 ++++++++++ include/linux/mailbox/mtk-cmdq-mailbox.h | 67 +++ include/linux/soc/mediatek/mtk-cmdq.h | 182 ++++++ 10 files changed, 1270 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
