usb: gadget: fsl: fix link error against usb-gadget module

2020-01-27T13:46:31+00:00

[ Upstream commit 2100e3ca3676e894fa48b8f6f01d01733387fe81 ]

The dependency to ensure this driver links correctly fails since
it can not be a loadable module:

drivers/usb/phy/phy-fsl-usb.o: In function `fsl_otg_set_peripheral':
phy-fsl-usb.c:(.text+0x2224): undefined reference to `usb_gadget_vbus_disconnect'

Make the option 'tristate' so it can work correctly.

usb: phy: fix link errors

set to module then the following link error occurs.

Rework so that FSL_USB2_OTG depends on that the USB_OTG_FSM is builtin.

usb: phy: Introduce one extcon device into usb phy

2017-05-17T11:15:28+00:00

Usually usb phy need register one extcon device to get the connection
notifications. It will remove some duplicate code if the extcon device
is registered using common code instead of each phy driver having its
own related extcon APIs. So we add one pointer of extcon device into
usb phy structure, and some other helper functions to register extcon.

Since the old common Samsung USB PHY code has been removed by commit ea2fdf8423
("usb: phy: samsung: remove old common USB PHY code"), thus remove the unused

usb: gadget: move gadget API functions to udc-core

2016-06-21T07:38:34+00:00

instead of defining all functions as static inlines,
let's move them to udc-core and export them with
EXPORT_SYMBOL_GPL, that way we can make sure that
only GPL drivers will use them.

As a side effect, it'll be nicer to add tracepoints
to the gadget API.

While at that, also fix Kconfig dependencies to
avoid randconfig build failures.

usb: phy: phy-am335x: bypass first VBUS sensing for host-only mode

2015-12-16T16:07:25+00:00

To prevent VBUS contention, the am335x MUSB phy senses VBUS first before
transitioning to host mode. However, for host-only mode, VBUS could be
directly tied to 5V power rail which could prevent MUSB transitions to
host mode.

This change receives dr_mode of the controller then bypass the first
VBUS sensing for host-only mode, so that MUSB can work in host mode
event if VBUS is tied to 5V.

usb: phy: Remove unused Renesas R-Car (Gen1) USB PHY driver

2015-12-15T15:12:41+00:00

As of commit 3d7608e4c169af03 ("ARM: shmobile: bockw: remove legacy
board file and config"), the Renesas R-Car (Gen1) USB PHY driver is no
longer used.
In theory it could still be used on R-Car Gen1 SoCs, but that would
require adding DT support to the driver. Instead, a new driver using the
generic PHY framework should be written, as was done for R-Car Gen2.

Remove the driver for good.

usb: kconfig: fix warning of select USB_OTG

2015-11-20T00:31:42+00:00

When choose randconfig for kernel build, it reports below warning:
"warning: (USB_OTG_FSM && FSL_USB2_OTG && USB_MV_OTG) selects USB_OTG
which has unmet direct dependencies (USB_SUPPORT && USB && PM)"

In fact, USB_OTG is visible symbol and depends on PM, so the driver
needs to depend on it to reduce dependency problem.
