The driver is actually for T-PHY which supports USB3.0, PCIe and SATA,
and supports more SoCs now, but not just only for series of mt65xx SoCs,
so the name of file, data struct, functions etc with 'mt65xx' may cause
misunderstanding when new SoCs are supported. Here rename them to reflect
the real functions and also enhance readability.
And also update MAINTAINERS file to reflect the correct driver

Some Motorola phones like droid 4 use a custom CPCAP PMIC that has a
multiplexing USB PHY.
This USB PHY can operate at least in four modes using pin multiplexing
and two control GPIOS:
- Pass through companion PHY for the SoC USB PHY
- ULPI PHY for the SoC
- Pass through USB for the modem
- UART debug console for the SoC
This patch adds support for droid 4 USB PHY and debug UART modes,
support for other modes can be added later on as needed.
Both peripheral and host mode are working for the USB. The
host mode depends on the cpcap-charger driver for VBUS.
VBUS and ID pin detection are done using cpcap-adc IIO ADC
driver.

With CONFIG_NVMEM=m and CONFIG_PHY_QCOM_QUSB2=y we get a link error from

Fix this by adding a Kconfig dependency to ensure we can only have this
driver built in when the nvmem functions are also built in or we see the
empty stub functions. We can still build this driver as a module when the
nvmem core is build as module, too.

This reverts commit d7bc1a7d41 ("phy: Add USB3 PHY support for

and NSP). It was added in commit e5666281d9 ("phy: bcm-ns-usb3: new
driver for USB 3.0 PHY on Northstar").
Instead of adding separated driver & duplicating code we should work on
improving existing (old) one. Thanks to work done by Broadcom we know
there is MDIO bus we weren't aware of & we know register names which
makes initialization more clear. This is very valuable info and we
should work on using it in existing driver afterwards.

This driver provides PHY init support in a generic way and can be bound
with XHCI controller driver.
There aren't any public datasheets from Broadcom so we can't have nice
defines for all used bits. It means we just follow Broadcom's
initialization procedure using their magic values. We were quite lucky
actually that Broadcom put some comments in their SDK reference code

Northstar is a family of SoCs used in home routers. They have USB 2.0
and 3.0 controllers with PHYs that need to be properly initialized.
This driver provides PHY init support in a generic way and can be bound
with an EHCI controller driver.
There are (just a few) registers being defined in bcma header. It's
because DMU/CRU registers will be also needed in other drivers. We will
need them e.g. in PCIe controller/PHY driver and at some point probably
in clock driver for BCM53573 chipset. By using include/linux/bcma/ we
avoid code duplication.

Add a new driver for the XUSB pad controller found on NVIDIA Tegra SoCs.
This hardware block used to be exposed as a pin controller, but it turns
out that this isn't a good fit. The new driver and DT binding much more
accurately describe the hardware and are more flexible in supporting new
SoC generations.

Currently, we have a common SATA3 PHY driver for all Broadcom
STB SoCs. This driver can be extended and re-used for Broadcom
iProc SoCs having same SATA3 PHY.

Make use of ARCH_RENESAS in place of ARCH_SHMOBILE.
A now redundant dependency on OF is also dropped.
This is part of an ongoing process to migrate from ARCH_SHMOBILE to
ARCH_RENESAS the motivation for which being that RENESAS seems to be a more
appropriate name than SHMOBILE for the majority of Renesas ARM based SoCs.

The phy-am335x driver selects 'USB_COMMON', but all other drivers
use 'depends on' for that symbol, and it depends on USB || USB_GADGET
itself, which causes a Kconfig warning:
warning: (AM335X_PHY_USB) selects USB_COMMON which has unmet direct dependencies (USB_SUPPORT && (USB || USB_GADGET))
As suggested by Felipe Balbi, this turns the logic around, and makes
'USB_COMMON' selected by everything else that needs it, so we can
remove the dependencies.

This patch adds support for R-Car generation 3 USB2 PHY driver.
This SoC has 3 EHCI/OHCI channels, and the channel 0 is shared
with the HSUSB (USB2.0 peripheral) device. And each channel has
independent registers about the PHYs.
So, the purpose of this driver is:
1) initializes some registers of SoC specific to use the
{ehci,ohci}-platform driver.
2) detects id pin to select host or peripheral on the channel 0.
For now, this driver only supports 1) above.
