This driver observes the USB ID pin connected over a GPIO and
updates the USB cable extcon states accordingly.
The existing GPIO extcon driver is not suitable for this purpose
as it needs to be taught to understand USB cable states and it
can't handle more than one cable per instance.
For the USB case we need to handle 2 cable states.
1) USB (attach/detach)
2) USB-HOST (attach/detach)
This driver can be easily updated in the future to handle VBUS
events in case it happens to be available on GPIO for any platform.

Device tree nodes are already treated as objects, and we already want to
expose them to userspace which is done using the /proc filesystem today.
Right now the kernel has to do a lot of work to keep the /proc view in
sync with the in-kernel representation. If device_nodes are switched to
be kobjects then the device tree code can be a whole lot simpler. It
also turns out that switching to using /sysfs from /proc results in
smaller code and data size, and the userspace ABI won't change if
/proc/device-tree symlinks to /sys/firmware/devicetree/base.
v7: Add missing sysfs_bin_attr_init()
v6: Add __of_add_property() early init fixes from Pantelis
v5: Rename firmware/ofw to firmware/devicetree
Fix updating property values in sysfs
v4: Fixed build error on Powerpc
Fixed handling of dynamic nodes on powerpc
v3: Fixed handling of duplicate attribute and child node names
v2: switch to using sysfs bin_attributes which solve the problem of
reporting incorrect property size.

With release of ACPI 5.1 and _DSD method we can finally name GPIOs (and
other things as well) returned by _CRS. Previously we were only able to
use integer index to find the corresponding GPIO, which is pretty error
prone if the order changes.
With _DSD we can now query GPIOs using name instead of an integer index,
like the below example shows:
// Bluetooth device with reset and shutdown GPIOs
Device (BTH)
{
Name (_HID, ...)
Name (_CRS, ResourceTemplate ()
{
GpioIo (Exclusive, PullUp, 0, 0, IoRestrictionInputOnly,
"\\_SB.GPO0", 0, ResourceConsumer) {15}
GpioIo (Exclusive, PullUp, 0, 0, IoRestrictionInputOnly,
"\\_SB.GPO0", 0, ResourceConsumer) {27, 31}
})
Name (_DSD, Package ()
{
ToUUID("daffd814-6eba-4d8c-8a91-bc9bbf4aa301"),
Package ()
{
Package () {"reset-gpio", Package() {^BTH, 1, 1, 0 }},
Package () {"shutdown-gpio", Package() {^BTH, 0, 0, 0 }},
}
})
}
The format of the supported GPIO property is:
Package () { "name", Package () { ref, index, pin, active_low }}
ref - The device that has _CRS containing GpioIo()/GpioInt() resources,
typically this is the device itself (BTH in our case).
index - Index of the GpioIo()/GpioInt() resource in _CRS starting from zero.
pin - Pin in the GpioIo()/GpioInt() resource. Typically this is zero.
active_low - If 1 the GPIO is marked as active_low.
Since ACPI GpioIo() resource does not have field saying whether it is
active low or high, the "active_low" argument can be used here. Setting
it to 1 marks the GPIO as active low.
In our Bluetooth example the "reset-gpio" refers to the second GpioIo()
resource, second pin in that resource with the GPIO number of 31.
This patch implements necessary support to gpiolib for extracting GPIOs
using _DSD device properties.

The huge majority of GPIOs have their direction and initial value set
right after being obtained by one of the gpiod_get() functions. The
integer GPIO API had gpio_request_one() that took a convenience flags
parameter allowing to specify an direction and value applied to the
returned GPIO. This feature greatly simplifies client code and ensures
errors are always handled properly.
A similar feature has been requested for the gpiod API. Since setting
the direction of a GPIO is so often the very next action done after
obtaining its descriptor, we prefer to extend the existing functions
instead of introducing new functions that would raise the
number of gpiod getters to 16 (!).
The drawback of this approach is that all gpiod clients need to be
updated. To limit the pain, temporary macros are introduced that allow
gpiod_get*() to be called with or without the extra flags argument. They
will be removed once all consumer code has been updated.

Introduce gpiod_get_optional() and gpiod_get_index_optional() helpers
that make it easier for drivers to handle optional GPIOs.
Currently in order to handle optional GPIOs, a driver needs to special
case error handling for -ENOENT, such as this:
gpio = gpiod_get(dev, "foo");
if (IS_ERR(gpio)) {
if (PTR_ERR(gpio) != -ENOENT)
return PTR_ERR(gpio);
gpio = NULL;
}
if (gpio) {
/* set up GPIO */
}
With these new helpers the above is reduced to:
gpio = gpiod_get_optional(dev, "foo");
if (IS_ERR(gpio))
return PTR_ERR(gpio);
if (gpio) {
/* set up GPIO */
}
While at it, device-managed variants of these functions are also
provided.

If the I2C is disturbed by other signals sometimes the i2c-imx bus gets stuck
with SDA being low.
This adds a recovery function to the bus driver.
When e.g. a device driver detects a stuck bus
int i2c_recover_bus(struct i2c_adapter *adap)
can be called to try to recover the bus.

This patch introduces generic code to perform PM domain look-up using
device tree and automatically bind devices to their PM domains.
Generic device tree bindings are introduced to specify PM domains of
devices in their device tree nodes.
Backwards compatibility with legacy Samsung-specific PM domain bindings
is provided, but for now the new code is not compiled when
CONFIG_ARCH_EXYNOS is selected to avoid collision with legacy code.
This will change as soon as the Exynos PM domain code gets converted to
use the generic framework in further patch.
This patch was originally submitted by Tomasz Figa when he was employed
by Samsung.

The 'big-endian-data' property is originally used to indicate whether the
LSB firstly or MSB firstly will be transmitted to the CODEC or received
from the CODEC, and there has nothing relation to the memory data.
Generally, if the audio data in big endian format, which will be using the
bytes reversion, Here this can only be used to bits reversion.
So using the 'lsb-first' instead of 'big-endian-data' can make the code
to be readable easier and more easy to understand what this property is
used to do.
This property used for configuring whether the LSB or the MSB is transmitted
first for the fifo data.

on i.mx5 since they share the same IP.
Note:

This allows to explicitly specify the covered bus numbers in the
devicetree, which will come in handy once we see a SoC with more than one
PCIe host controller instance.
Previously the driver relied on the behavior of pci_scan_root_bus() to fill
in a range of 0x00-0xff if no valid range was found. We fall back to the
same range if no valid DT entry was found to keep backwards compatibility,
but now do it explicitly.

The glue around the core designware IP is significantly different between
the Exynos and i.MX implementation, which is reflected in the DT bindings.
This changes the i.MX6 binding to reuse as much as possible from the common
designware binding and removes old cruft.
I removed the optional GPIOs with the following reasoning:
- disable-gpio: endpoint specific GPIO, not currently wired up in any code.
Should be handled by the PCI device driver, not the host controller
driver.
- wake-up-gpio: same as above.
- power-on-gpio: No user in any upstream DT. This should be handled by a
regulator which shouldn't be controlled by the host driver, but rather by
the PCI device driver.

1) asynchronous mode
Both Tx and Rx are set to be asynchronous.
2) synchronous mode (Rx sync with Tx)
Tx is set to be asynchronous, Rx is set to be synchronous.
3) synchronous mode (Tx sync with Rx)
Rx is set to be asynchronous, Tx is set to be synchronous.
4) synchronous mode (Tx/Rx sync with another SAI's Tx)
5) synchronous mode (Tx/Rx sync with another SAI's Rx)
* 4) and 5) are beyond this patch because they are related with another SAI.
As the initial version of this SAI driver, it supported 2) as default while
the others were totally missing.
So this patch just adds supports for 1) and 3).

This adds support for the USB PHY in Vybrid VF610. We assume that
the disconnection without VBUS is also needed for Vybrid.
Tests showed, without MXS_PHY_NEED_IP_FIX, enumeration of devices
behind a USB Hub fails with errors:
[ 215.163507] usb usb1-port1: cannot reset (err = -32)
[ 215.170498] usb usb1-port1: cannot reset (err = -32)
[ 215.185120] usb usb1-port1: cannot reset (err = -32)
[ 215.191345] usb usb1-port1: cannot reset (err = -32)
[ 215.202487] usb usb1-port1: cannot reset (err = -32)
[ 215.207718] usb usb1-port1: Cannot enable. Maybe the USB cable is bad?
[ 215.219317] usb usb1-port1: unable to enumerate USB device
Hence we also enable the MXS_PHY_NEED_IP_FIX flag.

The current imx-sgtl5000 driver always attaches the cpu-dai to ssi while
in fact it could be attached to other cpu-dais like SAI. Thus this patch
use a general code to support another cpu-dai. And meanwhile update the
devicetree for i.MX6 Series.

The current imx-wm8962 machine driver is designed for SSI as CPU DAI only
while as its name we should make the driver more generic to any other CPU
DAI on i.MX serires -- ESAI, SAI for example.
So this patch makes the driver more general so as to support those non-SSI
cases.

There're two GPIOs connected to the headphone jack and microphone jack,
thus add the states detection.
