usb: gadget: Use dbg_ep0() macro instead of serial_printf()

2021-03-03T03:12:46+00:00

All debug messages from ep0.c except a few are printed by dbg_ep0() macro.
So for remaining few exceptions use also dbg_ep0() instead of serial_printf().

usb: gadget: dwc2_udc_otg: Fix dwc2_gadget_start() and usb_gadget_register_driver()

2021-02-26T14:30:55+00:00

Since commit 8745b9ebccae ("usb: gadget: add super speed support")
ums was no more functional on platform which use dwc2_udc_otg driver.

This was due to a too restrictive test which checked that the gadget
driver speed was either FS or HS.

So all gadget driver with max speed set to speed higher than
HS (SS in case of composite gadget driver in our case) are not
allowed, which is wrong.

Update the speed test in usb_gadget_register_driver() and in
dwc2_gadget_start() to allow all gadget driver speed equal or higher
than FS.

Tested on stm32mp157c-ev1 board.

Fixes: c791c8431c34 ("usb: dwc2: convert driver to DM_USB_GADGET")

usb: dwc2: change compatible st,stm32mp1-hsotg to st,stm32mp15-hsotg

2021-02-10T21:23:35+00:00

The Linux kernel v5.7-rc1 introduced the compatible "st,stm32mp15-hsotg".

See Linux kernel commit d49850110434 ("dt-bindings: usb: dwc2: add
support for STM32MP15 SoCs USB OTG HS and FS")

This patch updates the supported compatible in DWC2 driver,
removes the add-on done in U-Boot dtsi and keeps the compatible
defined in SOC dtsi arch/arm/dts/stm32mp151.dtsi:

usbotg_hs: usb-otg@49000000 {
	compatible = "st,stm32mp15-hsotg", "snps,dwc2";
	reg = <0x49000000 0x10000>;

usb: composite: force gadget to be USB2 for HS only function

2021-01-31T13:08:56+00:00

If one of functions is not super speed capable, we need force the udc
to be high speed, this is an equivalent implementation of
usb_gadget_udc_set_speed() in kernel but simple, which set the gadget
max_speed to be high speed, so afterwards when start gadget duc can
set the HW to be USB 2.0 mode.
