Hi Jean-Jacques,

Quoted 10 lines

Resending this series after rebasing on top of latest u-boot. This series applies on top of the series "[PATCH v3 0/7] Improvements for the dwc3_generic driver"

Moving to DM_USB and DM_USB_DEV brings some benefits:
- it is required to support DM_ETH and USB network adapters with the same binary.
- support for USB3 on AM57x comes almost for free
- removal of platform code related to USB

Tested on:
- dra76 evm
- AM572 evm

I've tried to merge and test your patches:
SHA1: 0c4b382f9041f9f2f00246c8a0ece90dae5451be
https://github.com/lmajewski/u-boot-dfu/commits/testing

The updated repository is the same as above (SHA1 is of course different)

The "buildman" rockchip build breaks after applying your patches.

It breaks for e.g. OMAP.

Could you check this problem and resubmit patches?

Am I missing any more patches? Or maybe you have a Travis-CI "clean" branch/repo somewhere so I could use it ?

Thanks in advance,

Changes in v7:
- replace remaining if() statements with ut_assert()
- Fix build issue "multiple definition of `usb_gadget_handle_interrupts'"
- Fixed build issue "multiple definition of `usb_gadget_handle_interrupts'"

Changes in v6:
- ti-pipe3-phy: take PLL out of IDLE in pipe3_init(). The PLL may have been put into idle by pipe3_exit()
- DRA7 configs: enable DM_USB and DM_USB_DEV. Use DWC3_GENERIC in place of DWC3_OF_SIMPLE. disable non DM USB options
- AM57 configs: enable DM_USB and DM_USB_DEV. Use DWC3_GENERIC in place of DWC3_OF_SIMPLE. disable non DM USB options
- Supports DM USB for peripherals
- Removed DTS changes that disabled USB1 on DRA7 because DM_USB_DEV is now supported

Changes in v5:
- Rebased on latest u-boot
- Removed patches that have already been merged

Changes in v4:
- Fix word missing in commit log
- Remove dependency on MISC
- Renamed the commit (DM_USB is already enabled, the only missing option is for the USB2 phy driver)
- Remove dependency on MISC
- Remove omap specific glue layer and use dwc3-of-simple glue layer

Changes in v3:
- in syscon_regmap_lookup_by_phandle(), use dev_dbg() instead of printf()
- added unit test for syscon_regmap_lookup_by_phandle()

Changes in v2:
- Add USB3 support to ti-pipe3-phy driver
- omap-usb2-phy: Implement power_on and power_off callbacks
- am57xx boards: when DM_USB is used, turn on the required USB clocks
- split dts changes in 2 commits: one for binding the children of ocp2scp at 4a080000, and one to disable USB1 on all DRA7 EVMs
- Enable DM_USB in am57xx_evm_defconfig. USB3 (super speed) is supported.

syscon: dm: Add a new method to get a regmap from DTS
phy: Add a new driver for OMAP's USB2 PHYs
dwc3-generic: Add support for the TI DWC3 glue
board: ti: dra7xx-evm: turn on USB clocks in late init stage
dts: dra7x: make ocp2scp at 4a080000 compatible with simple-bus
configs: enable DM_USB and DM_USB_DEV for all DRA7 platforms
configs: am57xx_evm: Enable DM_USB and DM_USB_DEV
board: ti: dra7-evm: remove USB platform code
board: ti: am57xx: remove USB platform code
