These patches introduce the MediaTek USB3 dual-role controller driver. The driver can be configured as Dual-Role Device (DRD), Peripheral Only and Host Only (xHCI) modes. It works well with Mass Storage, RNDIS and g_zero on FS/HS and SS. And it is tested on MT8173 platform which only contains USB2.0 device IP, and on MT6290 platform which contains USB3.0 device IP. Change in v7: 1. split dual-role driver into four patchs 2. remove QMU done tasklet 3. add a bool in xhci_hcd_mtk to signal absence of IPPC Change in v6: 1. handle endianness of GPD and SETUP data 2. remove dummy error log and return suitable error number 3. cancel delay work when deregiseter driver Change in v5: 1. modify some comments 2. rename some unsuitable variables 3. add reg-names property for host node 4. add USB_MTU3_DEBUG to control debug messages Change in v4: 1. fix build errors on non-mediatek platforms 2. provide manual dual-role switch via debugfs instead of sysfs Change in v3: 1. fix some typo error 2. rename mtu3.txt to mt8173-mtu3.txt Change in v2: 1. modify binding docs according to suggestions 2. modify some comments and remove some dummy blank lines 3. fix memory leakage Chunfeng Yun (8): dt-bindings: mt8173-xhci: support host side of dual-role mode dt-bindings: mt8173-mtu3: add devicetree bindings usb: xhci-mtk: make IPPC register optional usb: Add MediaTek USB3 DRD driver usb: mtu3: Super-Speed Peripheral mode support usb: mtu3: host only mode support usb: mtu3: dual-role mode support arm64: dts: mediatek: add USB3 DRD driver .../devicetree/bindings/usb/mt8173-mtu3.txt | 87 ++ .../devicetree/bindings/usb/mt8173-xhci.txt | 54 +- arch/arm64/boot/dts/mediatek/mt8173-evb.dts | 63 +- arch/arm64/boot/dts/mediatek/mt8173.dtsi | 29 +- drivers/usb/Kconfig | 2 + drivers/usb/Makefile | 1 + drivers/usb/host/xhci-mtk.c | 38 +- drivers/usb/host/xhci-mtk.h | 1 + drivers/usb/mtu3/Kconfig | 54 ++ drivers/usb/mtu3/Makefile | 18 + drivers/usb/mtu3/mtu3.h | 417 +++++++++ drivers/usb/mtu3/mtu3_core.c | 859 +++++++++++++++++++ drivers/usb/mtu3/mtu3_dr.c | 379 +++++++++ drivers/usb/mtu3/mtu3_dr.h | 108 +++ drivers/usb/mtu3/mtu3_gadget.c | 730 ++++++++++++++++ drivers/usb/mtu3/mtu3_gadget_ep0.c | 881 ++++++++++++++++++++ drivers/usb/mtu3/mtu3_host.c | 294 +++++++ drivers/usb/mtu3/mtu3_hw_regs.h | 473 +++++++++++ drivers/usb/mtu3/mtu3_plat.c | 484 +++++++++++ drivers/usb/mtu3/mtu3_qmu.c | 573 +++++++++++++ drivers/usb/mtu3/mtu3_qmu.h | 43 + 21 files changed, 5561 insertions(+), 27 deletions(-) create mode 100644 Documentation/devicetree/bindings/usb/mt8173-mtu3.txt create mode 100644 drivers/usb/mtu3/Kconfig create mode 100644 drivers/usb/mtu3/Makefile create mode 100644 drivers/usb/mtu3/mtu3.h create mode 100644 drivers/usb/mtu3/mtu3_core.c create mode 100644 drivers/usb/mtu3/mtu3_dr.c create mode 100644 drivers/usb/mtu3/mtu3_dr.h create mode 100644 drivers/usb/mtu3/mtu3_gadget.c create mode 100644 drivers/usb/mtu3/mtu3_gadget_ep0.c create mode 100644 drivers/usb/mtu3/mtu3_host.c create mode 100644 drivers/usb/mtu3/mtu3_hw_regs.h create mode 100644 drivers/usb/mtu3/mtu3_plat.c create mode 100644 drivers/usb/mtu3/mtu3_qmu.c create mode 100644 drivers/usb/mtu3/mtu3_qmu.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
