When enabling ARCH_SUNXI from allnoconfig, SUNXI_SRAM is enabled, but
not REGMAP_MMIO, so the kernel fails to link with an undefined reference
to __devm_regmap_init_mmio_clk. Select REGMAP_MMIO, as suggested in
drivers/base/regmap/Kconfig.

This creates the following dependency loop:

  drivers/of/Kconfig:68:                symbol OF_IRQ depends on IRQ_DOMAIN

I noticed that musb is blocking core retention for omap4 unlike for
omap3. This is because for omap3 we have phy-twl4030-usb implement
it's own PM runtime to handle errata "VUSB3V1 VBUS overvoltage
debouncer not working when the PHY is powered down". That is done
in order to keep the USB PHY powered when phy-twl4030-usb is loaded.

For the other USB PHYs, we need to enable and disable the PHY based on
musb PM runtime. With the session bit based PM runtime for musb core,
we can now idle the USB PHY always when musb is idle.

Note that adding these calls will not affect the twl4030 driver
as it's phy functions will just query the PHY state without powering
the PHY on or off.

Fix two long-standing bugs which could potentially lead to memory
corruption or leave the port throttled until it is reopened (on weakly
ordered systems), respectively, when read-URB completion races with
unthrottle().

First, the URB must not be marked as free before processing is complete
to prevent it from being submitted by unthrottle() on another CPU.

	CPU 1				CPU 2
	================		================
	complete()			unthrottle()
	  process_urb();
	  smp_mb__before_atomic();
	  set_bit(i, free);		  if (test_and_clear_bit(i, free))
						  submit_urb();

Second, the URB must be marked as free before checking the throttled
flag to prevent unthrottle() on another CPU from failing to observe that
the URB needs to be submitted if complete() sees that the throttled flag
is set.

	CPU 1				CPU 2
	================		================
	complete()			unthrottle()
	  set_bit(i, free);		  throttled = 0;
	  smp_mb__after_atomic();	  smp_mb();
	  if (throttled)		  if (test_and_clear_bit(i, free))
		  return;			  submit_urb();

Note that test_and_clear_bit() only implies barriers when the test is
successful. To handle the case where the URB is still in use an explicit
barrier needs to be added to unthrottle() for the second race condition.

Also note that the first race was fixed by 36e59e0d ("cdc-acm: fix
race between callback and unthrottle") back in 2015, but the bug was
reintroduced a year later.

Immediate data transfers (IDT) allow the HCD to copy small chunks of
data (up to 8bytes) directly into its output transfer TRBs. This avoids
the somewhat expensive DMA mappings that are performed by default on
most URBs submissions.

In the case an URB was suitable for IDT. The data is directly copied
into the "Data Buffer Pointer" region of the TRB and the IDT flag is
set. Instead of triggering memory accesses the HC will use the data
directly.

The implementation could cover all kind of output endpoints. Yet
Isochronous endpoints are bypassed as I was unable to find one that
matched IDT's constraints. As we try to bypass the default DMA mappings
on URB buffers we'd need to find a Isochronous device with an
urb->transfer_buffer_length <= 8 bytes.

The implementation takes into account that the 8 byte buffers provided
by the URB will never cross a 64KB boundary.

It's pointless to scan the hub' i2c-bus segment if GPIOs aren't supported
by the system, since no GPIO-driven reset could be cleared by the driver
then. Moreover if CONFIG_GPIOLIB is disabled the gpio_chip structure
definition won't be available, which causes the incomplete type pointer
dereference compilation error. In order to fix this we need to create an
empty usb251x_check_gpio_chip() method returning zero, so the driver would
skip the i2c-bus segment checking and proceed with further probing in this
case.

VirtualLink standard extends the DisplayPort Alt Mode by
utilizing also the USB 2 pins on the USB Type-C connector.
It uses the same messages as DisplayPort, but not the DP
SVID. At the time of writing, USB IF has not assigned a
Standard ID (SID) for VirtualLink, so the manufacturers of
VirtualLink adapters use their Vendor IDs as the SVID.

Since the SVID specific communication is exactly the same as
with DisplayPort alternate mode, there is no need to
implement separate driver for VirtualLink. We'll handle the
current VirtualLink adapters with probe drivers, and once
there is SVID assigned for it, we add it to the displayport
alt mode driver.

To support probing drivers, exporting the probe and remove
functions, and also changing the DP_HEADER helper macro to
use the SVID of the alternate mode device instead of the
DisplayPort alt mode SVID.

With UCSI the alternate modes, just like everything else
related to USB Type-C connectors, are handled in firmware.
The operating system can see the status and is allowed to
request certain things, for example entering and exiting the
modes, but the support for alternate modes is very limited
in UCSI. The feature is also optional, which means that even
when the platform supports alternate modes, the operating
system may not be even made aware of them.

UCSI does not support direct VDM reading or writing.
Instead, alternate modes can be entered and exited using a
single custom command which takes also an optional SVID
specific configuration value as parameter. That means every
supported alternate mode has to be handled separately in
UCSI driver.

This commit does not include support for any specific
alternate mode. The discovered alternate modes are now
registered, but binding a driver to an alternate mode will
not be possible until support for that alternate mode is
added to the UCSI driver.

CCGx has two copies of the firmware in addition to the bootloader.
If the device is running FW1, FW2 can be updated with the new version.
Dual firmware mode allows the CCG device to stay in a PD contract and
support USB PD and Type-C functionality while a firmware update is in
progress.

First we read the currently flashed firmware version of both
primary and secondary firmware and then compare it with
version of firmware file to determine if flashing is required.

Command framework is added to support sending commands to CCGx
controller. We wait for response after sending the command and then
read the response from RAB_RESPONSE register.

Below commands are supported,
	- ENTER_FLASHING
	- RESET
	- PDPORT_ENABLE
	- JUMP_TO_BOOT
	- FLASH_ROW_RW
	- VALIDATE_FW

SMBus slave configuration is activated by CFG_SEL[1:0]=0x1 pins
state. This is the mode the hub is supposed to be to let this driver
work correctly. But a race condition might happen right after reset
is cleared due to CFG_SEL[0] pin being multiplexed with SMBus SCL
function. In case if the reset pin is handled by a i2c GPIO expander,
which is also placed at the same i2c-bus segment as the usb251x
SMB-interface connected to, then the hub reset clearance might
cause the CFG_SEL[0] being latched in unpredictable state. So
sometimes the hub configuration mode might be 0x1 (as expected),
but sometimes being 0x0, which doesn't imply to have the hub SMBus-slave
interface activated and consequently causes this driver failure.

In order to fix the problem we must make sure the GPIO-reset chip doesn't
reside the same i2c-bus segment as the SMBus-interface of the hub. If
it doesn't, we can safely block the segment for the time the reset is
cleared to prevent anyone generating a traffic at the i2c-bus SCL lane
connected to the CFG_SEL[0] pin. But if it does, nothing we can do, so
just return an error. If we locked the i2c-bus segment and tried to
communicate with the GPIO-expander, it would cause a deadlock. If we didn't
lock the i2c-bus segment, it would randomly cause the CFG_SEL[0] bit flip.

but if only ignores -ENOENT, it will cover some real errors, such as
-EPROBE_DEFER, so use devm_clk_get_optional() to get optional clock.

When the driver tries to get optional clock, it ignores all errors except
-EPROBE_DEFER, but if only ignores -ENOENT, it will cover some real errors,
such as -ENOMEM, so use devm_clk_get_optional() to get optional clock.
And remove unnecessary stack variable clk.

Use devm_clk_get_optional() to get optional clock instead of
optional_clk_get() which uses devm_clk_get() to get clock and
checks for -EPROBE_DEFER but not -ENOENT as devm_clk_get_optional()
does, in fact, only ignoring -ENOENT will cover more errors, so the
replacement doesn't change original purpose.
