There was an incorrect check when looping and finding the first
fast enough frequency in the freq_rang table. The code did
actually return the first that was either exactly correct or
too slow.

As a preparation for merging the socfpga gen5 devicetree files
from Linux, this patch makes the dwapb gpio driver work correctly
without the 'bank-name' property on the gpio-controller nodes.
This property is not present in the Linux drivers and thus is not
present in the Linux devicetrees. It is only used to access pins
via bank name.
This fallback is necessary since without it, the driver will
return an error code which will lead to an error in U-Boot
startup.
The bank names will still be added to the default board device
trees in follow-up patch, but other boards using this driver and
not including the bank name should also work with the socfpga.dtsi
without adding the bank-name property.

Many SoCs from MediaTek have a high-speed uart. This UART is compatible
with the ns16550 in legacy mode. It has extra registers for high-speed
mode which can reach a maximum baudrate at 921600.
However this UART will no longer be compatible if it's in high-speed mode.
Some BootROM of MediaTek's SoCs will change the UART into high-speed mode
and the U-Boot must use this driver to initialize the UART.

This adds a power domain driver for the Mediatek SCPSYS unit.
The System Control Processor System (SCPSYS) has several power
management related tasks in the system. The tasks include thermal
measurement, dynamic voltage frequency scaling (DVFS), interrupt
filter and lowlevel sleep control. The System Power Manager (SPM)
inside the SCPSYS is for the MTCMOS power domain control.
For now this driver only adds power domain support.

This patch adds pinctrl support for MT7629 SoC. The IO core found on
the SoC has the registers for pinctrl, pinconf and gpio mixed up in
the same register range. Hence the driver also implements the gpio
functionality through UCLASS_GPIO.
This also creates a common file as there might be other chips that use
the same binding and driver, then being a little more abstract could
help in the long run.

This patch adds clock modules for MediaTek SoCs:
- Shared part: a common driver which contains the general operations
for plls, muxes, dividers and gates so that we can reuse it in future.
- Specific SoC part: the group of structures used to hold the hardware
configuration for each SoC.
We take MT7629 as an example to demonstrate how to implement driver if
any other MediaTek chips would like to use it.

Comment in Linux driver says that clock needs to be doubled only
if we use DDR modes, moreover divider has to be set accordingly.
U-boot driver doesn't declare support for any DDR modes and doesn't
set internal clock divider in CLKCR, so it doubles clock
unconditionally when new mode is used.
Some cards can't handle that and as result SPL fails to load u-boot.

It is strange that function takes a private data structure from another

When the device tree is missing a correct spi slave description below
the bus (compatible "spi-flash" or spi-max-frequency are missing),
the 'set_speed' callback can be called with 'speed' == 0 Hz.
At least with cadence qspi, this leads to a division by zero.
Prevent this by initializing speed to 100 kHz in this case (same
fallback value as is done in 'dm_spi_claim_bus') and issue a warning
to console.
