Adjust this function so that it is passed an EHCI controller pointer so that
implementations can look up their controller.

At present the tegra driver uses a separate pointer to know which controller
type is in use. This works because only one controller type is used at a
time.
With driver model we want to make the controller state hermetic in the sense
that it is not necessary to look elsewhere to know the controller type. This
will permit a controller to implement the EHCI weak functions without
reference to global data structures.
To achieve this, define an enum for the controller type and store it with
the information on each EHCI controller.

Add a private data pointer that clients of EHCI can use to access their

The uclass pre-probe functions may end up calling back into the device in
some circumstances. This can fail if recursion takes place. Adjust the
ordering so that we mark the device as active early, then retract this
later if needed.

The existing get_get_of_data() function provides access to both the driver's

This commit adds driver model support to software emulated i2c bus driver.
This driver supports kernel-style device tree bindings. Fdt properties in use:
- compatible - "i2c-gpio"
- gpios - data and clock GPIO pin phandles
- delay-us - micro seconds delay between GPIOs toggle operations,
which is 1/4 of I2C speed clock period.
Added:
- Config: CONFIG_DM_I2C_GPIO
- File: drivers/i2c/i2c-gpio.c
- File: doc/device-tree-bindings/i2c/i2c-gpio.txt
Driver base code is taken from: drivers/i2c/soft-i2c.c, changes:
- use "i2c-gpio" naming
- update comments style
- move preprocesor macros into functions
- add device tree support
- add driver model i2c support
- code cleanup,
- add Kconfig entry

The function gpio_request_list_by_name_nodev() returned -ENOSPC error,
when the loop count was greater than requested count. This was wrong,
because function should return the requested gpio count, when meets
the call request without errors. Now, the loop ends on requested
max_count.

The U-Boot device trees are slightly different in a few places. Adjust them
to remove most of the differences. Note that U-Boot does not support the
concept of interrupts as distinct from GPIOs, so this difference remains.
For sandbox, use the same keyboard file as for ARM boards and drop the
host emulation bus which seems redundant.

Convert this driver over to use driver model. Since all x86 platforms use
it, move x86 to use driver model for SPI and SPI flash. Adjust all dependent
code and remove the old x86 spi_init() function.
Note that this does not make full use of the new PCI uclass as yet. We still
scan the bus looking for the device. It should move to finding its details
in the device tree.

The 'lo' interface on Linux doesn't support thinks like ARP or
link-layer access like we use to talk to a normal network interface.
A higher-level network API must be used to access localhost.
As written, this interface is limited to not supporting ICMP since the
API doesn't allow the socket to be opened for all IP traffic and be able
to receive at the same time. UDP is far more useful to test with, so it
was selected over ICMP. Ping won't work, but things like TFTP should
work.

Implement a bridge between U-Boot's network stack and Linux's raw packet
API allowing the sandbox to send and receive packets using the host
machine's network interface.
This raw Ethernet API requires elevated privileges. You can either run
as root, or you can add the capability needed like so:
sudo /sbin/setcap "CAP_NET_RAW+ep" /path/to/u-boot

Some uclasses want to set up a device before it is probed. Add a method
for this.
An example is with PCI, where a PCI uclass wants to set up its private
data for later use. This allows the device's uclass() method to make calls
whcih use that data (for example, read PCI memory regions from device
tree, set up bus numbers).

At present the device is not active when the probe() method is called. But
some probe() methods want to set up the device and this can involve
accessing it through normal methods. For example a PCI bus may wish to
set up its PCI parameters using calls to pci_hose_write_config_dword() and
similar.
At present this does not work because every such call within the probe()
method sees that the device is not active and attempts to probe it.
Already we mark the device as probed before calling the uclass post_probe()
method. This is a subtle change but I believe the new approach is better.
Since the scope of the change is only the probe() method and all its callees
it should still be within the control of the board author.

These functions currently use a generic name, but they are for x86 only.
This may introduce confusion and prevents U-Boot from using these names

Commit d3cfcb3 (ARM: DRA7: Enable clocks for USB OTGSS and USB PHY)
changed the member names of prcm_regs from cm_l3init_usb_otg_ss_clkctrl
to cm_l3init_usb_otg_ss1_clkctrl and from cm_coreaon_usb_phy_core_clkctrl
to cm_coreaon_usb_phy1_core_clkctrl in order to differentiate between
the two dwc3 controllers present in dra7xx/am43xx and enabled these
clocks in enable_basic_clocks() in hw_data.c. However these clocks
continued to be enabled in board files/driver files for dwc3 host
mode functionality causing compilation break with few configs.
Fixed it here by making all the clocks enabled in enable_basic_clocks()
and removing it from board files/driver files here.
