configs: ti: use standard configuration nodes naming
Currently, any u-boot bootloader for ti armv7 platforms using
DEFAULT_FIT_TI_ARGS to boot with a fitimage (boot_fit = 1)
doesn't boot when built with Yocto Poky (openembedded-core).
## Loading kernel from FIT Image at 90000000 ...
Could not find configuration node
ERROR: can't get kernel image!
Arago forked the kernel-fitimage class [1] and altered the
configuration nodes naming while adding the OPTEE support by
using FITIMAGE_CONF_BY_NAME by default [2].
The "upstream" kernel-fitimage class from openembedded-core still
add the "conf-" prefix for each configuration nodes [3].
The ITS file format (from doc/uImage.FIT/source_file_format.txt)
is not really accurate with the expected naming of these nodes.
But in practice the "conf-" prefix is widely used.
When the FIT image support has been added for ti armv7 platforms
the naming from Arago has been used [3]. Fix this issue by adding
the prefix expected by the ITS file generated by kernel-fitimage
class from openembedded-core.

-d option is currently broken. In most cases BootROM does not detect this
message pattern. For sending debug message pattern it is needed to do same
steps as for boot message pattern.
Implement sending debug message pattern via same separate thread like it is
for boot message pattern.
Checking if BootROM entered into UART debug mode is different than
detecting UART boot mode. When in boot mode, BootROM sends xmodem NAK
bytes. When in debug mode, BootROM activates console echo and reply back
every written byte (extept \r\n which is interpreted as executing command
and \b which is interpreting as removing the last sent byte).
So in kwboot, check that BootROM send back at least 4 debug message
patterns as a echo reply for debug message patterns which kwboot is sending
in the loop.
Then there is another observation, if host writes too many bytes (as
command) then BootROM command line buffer may overflow after trying to
execute such long command. To workaround this overflow, it is enough to
remove bytes from the input line buffer by sending 3 \b bytes for every
sent character. So do it.
With this change, it is possbile to enter into the UART debug mode with
kwboot -d option.

tools: kwboot: Use separate thread for sending boot message pattern
After BootROM successfully detects boot message pattern on UART it waits
until host stop sending data on UART. For example Armada 385 BootROM
requires that host does not send anything on UART at least 24 ms. If host
is still sending something then BootROM waits (possibly infinitely).
BootROM successfully detects boot message pattern if it receives it in
small period of time after power on.
So to ensure that host put BootROM into UART boot mode, host must send
continuous stream of boot message pattern with a small gap (for A385 at
least 24 ms) after series of pattern. But this gap cannot be too often or
too long to ensure that it does not cover whole BootROM time window when it
is detecting for boot message pattern.
Therefore it is needed to do following steps in cycle without any delay:
1. send series of boot message pattern over UART
2. wait until kernel transmit all data
3. sleep small period of time
At the same time, host needs to monitor input queue, data received on the
UART and checking if it contains NAK byte by which BootROM informs that
xmodem transfer is ready.
But it is not possible to wait until kernel transmit all data on UART and
at the same time in the one process to also wait for input data. This is
limitation of POSIX tty API and also by linux kernel that it does not
provide asynchronous function for waiting until all data are transmitted.
There is only synchronous variant tcdrain().
So to correctly implement this handshake on systems with linux kernel, it
is needed to use tcdrain() in separate thread.
Implement sending of boot message pattern in one thread and reading of
reply in the main thread. Use pthread library for threads.
This change makes UART booting on Armada 385 more reliable. It is possible
to start kwboot and power on board after minute and kwboot correctly put
board into UART boot mode.
Old implementation without separate thread has an issue that it read just
one byte from UART input queue and then it send 128 message pattern to the
output queue. If some noise was on UART then kwboot was not able to read
BootROM response as its input queue was just overflowed and kwboot was
sending more data than receiving.
This change basically fixed above issue too.

arm: a37xx: pci: Fix a3700_fdt_fix_pcie_regions() function again
The a3700_fdt_fix_pcie_regions() function still computes nonsense.
It computes the fixup offset from the PCI address taken from the first
row of the "ranges" array, which means that:
- PCI address must equal CPU address (otherwise the computed fix offset
will be wrong),
- the first row must contain the lowest address.
This is the case for the default device-tree, which is why we didn't
notice it.
It also adds the fixup offset to all PCI and CPU addresses, which is
wrong.
Instead:
1) The fixup offset must be computed from the CPU address, not PCI
address.
2) The fixup offset must be computed from the row containing the lowest
CPU address, which is not necessarily contained in the first row.
3) The PCI address - the address to which the PCIe controller remaps the
address space as seen from the point of view of the PCIe device -
must be fixed by the fix offset in the same way as the CPU address
only in the special case when the CPU adn PCI addresses are the same.
Same addresses means that remapping is disabled, and thus if we
change the CPU address, we need also to change the PCI address so
that the remapping is still disabled afterwards.
Now it will take the lowest CPU address, which is in second row, E9000000, and compute the fix offset F2000000 - E9000000 = 09000000,
and then add it to all CPU addresses and those PCI addresses which
equal to their corresponding CPU addresses, resulting in
PCI address CPU address 70000000F3000000 F2000000F2000000 F4000000F4000000

The latter is a self-signed CA certificate and with our current implementation

clk: Add client API to HTML docs
This converts the existing client (aka clk.h) documentation to kernel doc
format, and adds it to the HTML docs. I have tried to preserve existing
comments as much as possible, refraining from semantic changes.

clk: Inline clk_get_*_optional
The optional varients of clk_get_* functions are just simple wrappers.
Reduce code size a bit by inlining them. On platforms where it is not used
(most of them), it will not be compiled in any more. On platforms where
they are used, the inlined branch should not cause any significant growth.

usb: ehci-omap: Remove OMAP_EHCI_PHYx_RESET_GPIO from Kconfig
With the omap-ehci driver now using the phy subsystem to enable
and disable reset, the driver no longer needs to know which
GPIO's are used, and they can be removed from Kconfig.

usb: ehci-omap: Use PHY system to manage phy resets
There are a few boards that use hard-coded GPIO definitions in
their respective defconfig files. If the GPIO's are listed
in their device trees, the nop-phy can toggle the GPIO's,
so the EHCI driver does not need to know anything about the
GPIO's. Add functions for getting the phys and remove the GPIO
toggles since the phy will now do that.

usb: ehci-omap: Make Kconfig select PHY if USB_EHCI_OMAP
The USB_EHCI_OMAP driver currently has a series of Kconfig options
which let users specify a GPIO for the reset pin. Some devices
may have only one reset, while others might have more.
Since there is a nop phy driver, let's selct enable the PHY
system, and imply the nop phy driver. The nop phy driver can now
toggle the reset pins when putting the phy in and out of reset.
If the gpio is listed under the phy, it will get toggled and
the hard-coded config options specifying the GPIO numbers can
eventually go away.

phy: nop-phy: Fix enabling reset
The reset function should place the phy into reset, while the
init function should take the phy out of reset. Currently the
reset function takes it out of reset, and the init calls the

usb: ehci-omap: Drop dead code
omap_ehci_hcd_stop appears to be dead code, and omap_ehci_hcd_init
is only called by the probe function, so it can be static to that
function. Remove both from the header along with some additional
checking for DM_USB.
On some configs (like stm32mp15_dhcom_basic_defconfig), if configs
SPL_LOAD_FIT_FULL and SPL_FIT_FULL_CHECK are enabled. Then the compilatio
fails with the following error:
arm-linux-gnueabi-ld.bfd: boot/image-fit.o: in function `fit_check_format':
<PATH>/uboot/u-boot-stm/boot/image-fit.c:1641: undefined reference to `fdt_check_full'
scripts/Makefile.spl:509: recipe for target 'spl/u-boot-spl' failed
This issue happens because the function fdt_check_full is only defined if
"!defined(FDT_ASSUME_MASK) || FDT_ASSUME_MASK != 0xff". But this function
may be called even if this condition are not verified. To avoid this issue,
the function fdt_check_full is always defined.

At present the 'args' property of the mkimage entry type is a string. This
