George Spelvin 035978beaf usb: phy: Improve Kconfig help for CONFIG_USB_PHY
The previous text confused users by not describing the very common
(e.g. x86 PC) sitations where no PHY driver is necessary.

# Physical Layer USB driver configuration
#
menuconfig USB_PHY
bool "USB Physical Layer drivers"
help
Most USB controllers have the physical layer signalling part
(commonly called a PHY) built in. However, dual-role devices
(a.k.a. USB on-the-go) which support being USB master or slave
with the same connector often use an external PHY.
The drivers in this submenu add support for such PHY devices.
They are not needed for standard master-only (or the vast
majority of slave-only) USB interfaces.
If you're not sure if this applies to you, it probably doesn't;
say N here.

depends on I2C && ARCH_OMAP_OTG
help
If you say yes here you get support for the Philips ISP1301
USB-On-The-Go transceiver working with the OMAP OTG controller.
The ISP1301 is a full speed USB transceiver which is used in
products including H2, H3, and H4 development boards for Texas
Instruments OMAP processors.
This driver can also be built as a module. If so, the module
will be called isp1301_omap.

depends on CPU_MMP3
help
Enable this to support Marvell USB 3.0 phy controller for Marvell
SoC.
config NOP_USB_XCEIV
tristate "NOP USB Transceiver Driver"
help
This driver is to be used by all the usb transceiver which are either
built-in with usb ip or which are autonomous and doesn't require any
phy programming such as ISP1x04 etc.
config OMAP_CONTROL_USB
tristate "OMAP CONTROL USB Driver"
help
Enable this to add support for the USB part present in the control
module. This driver has API to power on the USB2 PHY and to write to
the mailbox. The mailbox is present only in omap4 and the register to
power on the USB2 PHY is present in OMAP4 and OMAP5. OMAP5 has an
additional register to power on USB3 PHY.
config OMAP_USB2
tristate "OMAP USB2 PHY Driver"
depends on ARCH_OMAP2PLUS
select OMAP_CONTROL_USB
help
Enable this to support the transceiver that is part of SOC. This
driver takes care of all the PHY functionality apart from comparator.
The USB OTG controller communicates with the comparator using this
driver.
config OMAP_USB3
tristate "OMAP USB3 PHY Driver"
select OMAP_CONTROL_USB
help
Enable this to support the USB3 PHY that is part of SOC. This
driver takes care of all the PHY functionality apart from comparator.
This driver interacts with the "OMAP Control USB Driver" to power
on/off the PHY.
config SAMSUNG_USBPHY
tristate "Samsung USB PHY Driver"
help
Enable this to support Samsung USB phy helper driver for Samsung SoCs.
This driver provides common interface to interact, for Samsung USB 2.0 PHY
driver and later for Samsung USB 3.0 PHY driver.
config SAMSUNG_USB2PHY
tristate "Samsung USB 2.0 PHY controller Driver"
select SAMSUNG_USBPHY
help
Enable this to support Samsung USB 2.0 (High Speed) PHY controller
driver for Samsung SoCs.
config SAMSUNG_USB3PHY
tristate "Samsung USB 3.0 PHY controller Driver"
select SAMSUNG_USBPHY
help
Enable this to support Samsung USB 3.0 (Super Speed) phy controller
for samsung SoCs.
config TWL4030_USB
tristate "TWL4030 USB Transceiver Driver"
depends on TWL4030_CORE && REGULATOR_TWL4030 && USB_MUSB_OMAP2PLUS
help
Enable this to support the USB OTG transceiver on TWL4030

This transceiver supports high and full speed devices plus,
in host mode, low speed.
config TWL6030_USB
tristate "TWL6030 USB Transceiver Driver"
depends on TWL4030_CORE && OMAP_USB2 && USB_MUSB_OMAP2PLUS
help
Enable this to support the USB OTG transceiver on TWL6030
family chips. This TWL6030 transceiver has the VBUS and ID GND
and OTG SRP events capabilities. For all other transceiver functionality
UTMI PHY is embedded in OMAP4430. The internal PHY configurations APIs
are hooked to this driver through platform_data structure.
The definition of internal PHY APIs are in the mach-omap2 layer.
config USB_GPIO_VBUS
tristate "GPIO based peripheral-only VBUS sensing 'transceiver'"
depends on GPIOLIB
help
Provides simple GPIO VBUS sensing for controllers with an
internal transceiver via the usb_phy interface, and
