Changes to the DWC2 (OTG) and/or OHCI (Host) are still needed to make USB on the MP1 work. I haven't yet groked the relation between generic phy and usb phy frameworks, but the code is a straight port from Linux and it seems to work[1], so let's upstream it now to make collaboration easier. [1]: clock the EHCI and power on the PHY and 20% of the time, the bus can be enumerated completely. Still needs further debugging, but it's unlikely that the PHY driver is at fault. Cheers, Ahmad Fatoum (6): regulator: import Linux regulator_bulk API phy: remove unused init_data parameter phy: populate existing ->pwr member with phy-supply phy: introduce phy_get_by_index regulator: port over Linux stm32 PWR regulator driver phy: port over Linux stm32 usbphyc driver drivers/phy/Kconfig | 13 + drivers/phy/Makefile | 1 + drivers/phy/freescale/phy-fsl-imx8mq-usb.c | 2 +- drivers/phy/phy-core.c | 29 +- drivers/phy/phy-stm32-usbphyc.c | 434 +++++++++++++++++++++ drivers/phy/usb-nop-xceiv.c | 2 +- drivers/pinctrl/pinctrl-tegra-xusb.c | 4 +- drivers/regulator/Kconfig | 7 + drivers/regulator/Makefile | 1 + drivers/regulator/core.c | 139 +++++++ drivers/regulator/stm32-pwr.c | 215 ++++++++++ drivers/usb/imx/imx-usb-phy.c | 2 +- include/linux/phy/phy.h | 14 +- include/regulator.h | 49 +++ 14 files changed, 897 insertions(+), 15 deletions(-) create mode 100644 drivers/phy/phy-stm32-usbphyc.c create mode 100644 drivers/regulator/stm32-pwr.c -- 2.25.0 _______________________________________________ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox
