Hi Marek, Do you plan to take this series or does it need some rework?
I'm hoping to build on it to support DM_USB on the TI platforms. JJ On 29/05/2018 14:36, Jean-Jacques Hiblot wrote:
This series aims at bringing improvements to the dwc3_generic driver so that it can be used by most of the platforms using the dwc3 controller. This series applies on top of the master branch of USB tree. It also also available on github: https://github.com/jjhiblot/u-boot/tree/dwc3_generic_v2 I tested this on with DRA7 and AM57x platforms for both Peripheral and Host operations. The code to enable DM USB host & dev support for those platforms will be submitted in a separate series. Enhancements: - use separate Kconfig option for DM USB Periphal and DM USB Host. This allow platforms to keep their non-DM USB peripheral code and use the DM USB host. - fixes the bind/probe confusion in dwc3_generic. The probe is done when the USB device is first needed. - handles PHYs when in the peripheral mode. The code to handle the PHYs is shared with the host side - handles clock and reset - bind host controller to the more generic driver 'xhci-dwc3' Changes in v2: - Updated commit log - Fixed typo in thordown.c - select DM_USB_DEV by default for zynqmp platforms Jean-Jacques Hiblot (7): usb: gadget: Do not call board_usb_xxx() directly in USB gadget drivers usb: introduce a separate config option for DM USB device usb: udc: implement DM versions of usb_gadget_initialize()/_release()/_handle_interrupt() dwc3_generic: do not probe the USB device driver when it's bound dwc3: move phy operation to core.c dwc3-generic: Handle the PHYs, the clocks and the reset lines dwc3-generic: Add select_dr_mode operation arch/arm/Kconfig | 2 + cmd/fastboot.c | 4 +- cmd/rockusb.c | 4 +- cmd/thordown.c | 4 +- cmd/usb_gadget_sdp.c | 4 +- cmd/usb_mass_storage.c | 4 +- common/dfu.c | 6 +- drivers/usb/Kconfig | 6 ++ drivers/usb/dwc3/Kconfig | 7 +- drivers/usb/dwc3/core.c | 86 +++++++++++++++- drivers/usb/dwc3/dwc3-generic.c | 207 +++++++++++++++++++++++++++++--------- drivers/usb/dwc3/ep0.c | 1 - drivers/usb/gadget/ether.c | 38 +------ drivers/usb/gadget/udc/udc-core.c | 44 +++++++- drivers/usb/host/xhci-dwc3.c | 93 ++--------------- include/dwc3-uboot.h | 7 ++ include/linux/usb/gadget.h | 18 ++++ 17 files changed, 351 insertions(+), 184 deletions(-)
