Hi, This is Mediatek MT8173 Command Queue(CMDQ) driver. The CMDQ is used to help read/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 v4.5-rc1. Changes since v2: - use cmdq instead of cqctx - document cmdq_code - use cmdq thread base instead of thread id, so remove thread id - remove buffer pool and let linux manage memory - remove task_free_list - merge cmdq_task_exec_async_impl into cmdq_task_exec_async - use list_for_each_entry_safe instead of list_for_each_safe - merge cmdq_dev_init into cmdq_probe - use cmdq record(rec) instead of cmdq handle - use cmdq command instead of cmdq desc - remove unused interfaces - set IRQF_TRIGGER_LOW in device tree - remove event array and related code since client should clear event before wait it - report status to callback function - remove some debug code - remove some protection code, e.g. suspend/resume - rewrite some code to shrink code size Best regards, HS Liao HS Liao (3): dt-bindings: soc: Add documentation for the MediaTek GCE unit CMDQ: Mediatek CMDQ driver arm64: dts: mt8173: Add GCE node .../devicetree/bindings/soc/mediatek/gce.txt | 34 + arch/arm64/boot/dts/mediatek/mt8173.dtsi | 8 + drivers/soc/mediatek/Kconfig | 10 + drivers/soc/mediatek/Makefile | 1 + drivers/soc/mediatek/mtk-cmdq.c | 1805 ++++++++++++++++++++ include/soc/mediatek/cmdq.h | 181 ++ 6 files changed, 2039 insertions(+) create mode 100644 Documentation/devicetree/bindings/soc/mediatek/gce.txt create mode 100644 drivers/soc/mediatek/mtk-cmdq.c create mode 100644 include/soc/mediatek/cmdq.h -- 1.7.9.5 -- 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
