doc: replace @return by Return:

2022-01-19T17:11:34+00:00

Sphinx expects Return: and not @return to indicate a return value.

find . -name '*.c' -exec \
sed -i 's/^\(\s\)\*\(\s*\)@return\(\s\)/\1*\2Return:\3/' {} \;

find . -name '*.h' -exec \

usb: ehci-mx6: use phy_type from device tree

2021-09-22T19:29:56+00:00

Allow using different PHY interfaces for multiple USB controllers. When no
value is set in DT, we fall back to CONFIG_MXC_USB_PORTSC for now to stay
compatible with current board configurations.

This also adds support for the HSIC mode of the i.MX7.

usb: ehci-ci: remove redundant PORTSC flag definitions

2021-09-22T19:29:56+00:00

These definitions are unused, all boards that define portsc flags use
the equivalent PORT_* definitions instead.

usb: xhci-pci: Move reset logic out of XHCI core

2021-09-22T19:29:56+00:00

Resetting an XHCI controller inside xhci_register undoes any register
setup performed by the platform driver. And at least on the Allwinner
H6, resetting the XHCI controller also resets the PHY, which prevents
the controller from working. That means the controller must be taken out
of reset before initializing the PHY, which must be done before calling
xhci_register.

The logic in the XHCI core was added to support the Raspberry Pi 4
(although this was not mentioned in the commit log!), which uses the
xhci-pci platform driver. Move the reset logic to the platform driver,
where it belongs, and where it cannot interfere with other platform
drivers.

This also fixes a failure to call reset_free if xhci_register failed.

xhci: translate virtual addresses into the bus's address space

2021-02-18T10:56:26+00:00

So far we've been content with passing physical addresses when
configuring memory addresses into XHCI controllers, but not all
platforms have buses with transparent mappings. Specifically the
Raspberry Pi 4 might introduce an offset to memory accesses incoming
from its PCIe port.

Introduce xhci_virt_to_bus() and xhci_bus_to_virt() to cater with these
limitations, and make sure we don't break non DM users.

usb: dwc2: add "u-boot,force-vbus-detection" for stm32

2020-11-22T12:18:20+00:00

On some board, the ID pin is not connected so the B session must be
overridden with "u-boot,force_b_session_valid" but the VBus sensing
must continue to be handle.

To managed it, this patch adds a new DT field
"u-boot,force-vbus-detection" to use with "u-boot,force_b_session_valid"
