usb: host: dwc3-sti-glue: Use UCLASS_NOP instead of UCLASS_MISC

2020-04-28T11:52:52+00:00

dwc3-sti-glue has been broken since MISC uclass has been
modified to scan DT sub-nodes after bind.
Fixing it by a using the no-op uclass.

usb: host: dwc2: add trace to have clean usb start

2020-04-28T11:52:52+00:00

Solve issue for the display of "usb start" command on stm32mp1
because one carriage return is missing in DWC2 probe.

Before the patch:

STM32MP> usb start
starting USB...
Bus usb-otg@49000000:    Bus usbh-ehci@5800d000:   USB EHCI 1.00

after the patch:

STM32MP> usb start
starting USB...
Bus usb-otg@49000000: USB DWC2
Bus usbh-ehci@5800d000: USB EHCI 1.00

usb: host: dwc2: force reset assert

2020-04-28T11:52:52+00:00

Assert reset before deassert in dwc2_reset;
this patch solve issues when the DWC2 registers are already
initialized with value incompatible with host mode.

Force a hardware reset of the IP reset all the DWC2 registers at
default value, the host driver start with a clean state
(Core Soft reset doen in dwc_otg_core_reset is not enought
 to reset all register).

The error can occurs in U-Boot when DWC2 device gadget driver
force device mode (called by ums or dfu command, before to execute
the usb start command).

usb: host: dwc2: add clk support

2020-04-28T11:52:52+00:00

Add support for clock with driver model.

This patch don't added dependency because when CONFIG_CLK
is not activated the clk function are stubbed.

usb: host: dwc2: add phy support

2020-04-28T11:52:52+00:00

Use generic phy to initialize the PHY associated to the
DWC2 device and available in the device tree.

This patch don't added dependency because when CONFIG_PHY
is not activated, the generic PHY function are stubbed.

usb: dwc3-meson-g12a: add power-on/off of the PHYs

2020-04-28T08:23:10+00:00

Power on/off the PHYs to enable power to the USB ports, fixing USB support
on Khadas VIM3/VIM3L boards.

The G12A USB complex has at least 2 USB2 PHYs, but one is muxed between the
DWC2 and DWC3 controller and the other one directly connected to the DWC3
controller. The USB3+PCIe combo PHY is muxed between the DWC3 controller
and a DW-PCIE controller.
All PHYs are optional, but it's type (usb2/usb3) and position are important
to determine it's capabilities, thus they are stored in a fixed size
array and the phy-name determines it's position, it's position determining
it's type and functionnalities.
This is why we need to loop over the array to power on all the DT provided
PHYs.
