Instead of using a fixed-size array to store variable name, preferring a dynamic allocation treats correctly all variable name lengths.
Variable names are growing through releases and features. By this way, name clipping is prevented.

The 'clock-freq-min-max' property was deprecated in the upstream
(i.e. Linux) DTS bindings in favor of the 'max-frequency' property.
With the latest RK3399 DTSI does no longer include the deprecated
property and the rockchip_dw_mmc driver requiring it to be present,
the driver doesn't bind to the node in the RK3399 DTSI any longer
(thus breaking access to the SD card on the RK3399-Q7 board).
To fix this, we implement a similar logic as in the Linux driver: if
the deprecated property is present, we issue a warning (if DEBUG is
enabled); if it is missing, we require 'max-frequency' to be set and
use it to create a min/max value-pair.

The baudrate in rkspi was calculated by using an integer division
(which implicitly discarded any fractional result), then rounding to
an even number and finally clamping to 0xfffe using a bitwise AND
operator. This introduced two issues:
1) for very small baudrates (overflowing the 0xfffe range), the
bitwise-AND generates rather random-looking (wildly varying)
actual output bitrates
2) for higher baudrates, the calculation tends to 'err towards a
higher baudrate' with the actual error increasing as the dividers
become very small. E.g., with a 99MHz input clock, a request
for a 20MBit baudrate (99/20 = 4.95), a 24.75 MBit would be use
(which amounts to a 23.75% error)... for a 34 MBit request this
would be an actual outbout of 49.5 Mbit (i.e. a 45% error).
This change rewrites the divider selection (i.e. baudrate calculation)
by making sure that
a) for the normal case: the largest representable baudrate below the
requested rate will be chosen;
b) for the denormal case (i.e. when the divider can no longer be
represented), the lowest representable baudrate is chosen.
Even though the denormal case (b) may be of little concern in real
world applications (even with a 198MHz input clock, this will only
happen at below approx. 3kHz/3kBit), our board-verification team kept
complaining.

The original clock/bitrate selection code for the rk_spi driver was a
bit limited, as it always selected a 99MHz input clock rate (which
would allow for a maximum bitrate of 49.5MBit/s), but returned -EINVAL
if a bitrate higher than 48MHz was requested.
To give us better control over the bitrate (i.e. add more operating
points, especially at "higher" bitrate---such as above 9MBit/s), we
try to choose 4x the maximum frequency (clamped to 50MBit) from the
DTS instead of 99MHz... for most use-cases this will yield a frequency
of 198MHz, but is flexible to go beyond this in future configurations.
This also rewrites the check to allow frequencies of up to half the
SPI module rate as bitrates and then clamps to whatever the DTS allows
as a maximum (board-specific) frequency and does away with the -EINVAL
when trying to select a bitrate (for cases that exceeded the hard
limit) and instead consistently clamps to the lower of the hard limit,
the soft limit for the SPI bus (from the DTS) or the soft limit for
the SPI slave device.
This replaces
"rockchip: spi: rk_spi: select 198MHz input to the SPI module for the RK3399"
"rockchip: spi: rk_spi: improve clocking code for the RK3399"
from earlier versions of this series.

For the RK3399, i2c_set_rate (and by extension: our spi_set_rate,
which had been mindlessly following the template of the i2c_set_rate
implementation) miscalculates the rate returned due to a off-by-one
error resulting from the following sequence of events:
1. calculates 'src_div := src_freq / target_freq'
2. stores 'src_div - 1' into the register (the actual divider applied
in hardware is biased by adding 1)
3. returns the result of the DIV_RATE(src_freq, src_div) macro, which
expects the (decremented) divider from the hardware-register and
implictly adds 1 (i.e. 'DIV_RATE(freq, div) := freq / (div + 1)')
This can be observed with the SPI driver, which sets a rate of 99MHz
based on the GPLL frequency of 594MHz: the hardware generates a clock
of 99MHz (src_div is 6, the bitfield in the register correctly reads 5),
but reports a frequency of 84MHz (594 / 7) on return.
To fix, we have two options:
* either we bias (i.e. "DIV_RATE(GPLL, src_div - 1)"), which doesn't
make for a particularily nice read
* we simply call the i2c/spi_get_rate function (introducing additional
overhead for the additional register-read), which reads the divider
from the register and then passes it through the DIV_RATE macro
Given that this code is not time-critical, the more readable solution
(i.e. calling the appropriate get_rate function) is implemented in this
change.

This type tells u-boot to preserve the COMPHY settings as is
it is usefull in situations where the COMPHY was initialized by
earlier firmware.
Note that IGNORE is different from UNCONNECTED since setting
UNCONNECTED type will disconnect the COMPHY in the COMPHY MUX
which is a desired behaviour

UTMI_PHY_TO_USB_HOST was used in USB3 UTMI dts node only, but there will
be USB2 UTMI dts node for some SoCs that have got USB2 controller, so rename
TO_USB_HOST to TO_USB3_HOST to distinguish TO_USB2_HOST in later on patches.

Use local static counter for maintaining the COMPHY chip-ID
upon its initialization.
The dev->seq originally used as the COMPHY chip-ID depends
on the device tree scan order and produces wrong results
that breaks the deficated PHYs init flow, which in turn
breaks the USB support.

This patch allows probing all PCIe nodes defined in DTS
even if there no device connected to such node (no link).
Without this fix the driver returns -ENODEV when the PCIe
link is down. As result the pci_init function stops
scanning bus on first empty PCIe slot and all devices
located in higher numbered buses are not discovered.

The i2c driver will be converted to support device model. In preparation
for that change split the various functions into two parts. This will
allow device model specific driver to reuse the majority of the code from
the non device model implementation.
Also rename the probe function to probe_chip to better reflect its
purpose.

Add support for clocks needed by MACs to ast2500 clock driver.
The clocks are D2-PLL, which is used by both MACs and PCLK_MAC1 and
PCLK_MAC2 for MAC1 and MAC2 respectively.
The rate of D2-PLL is hardcoded to 250MHz -- the value used in Aspeed
SDK. It is not entirely clear from the datasheet how this clock is used
by MACs, so not clear if the rate would ever need to be different. So,
for now, hardcoding it is probably safer.
The rate of PCLK_MAC{1,2} is chosen based on MAC speed selected through
hardware strapping.
So, the network driver would only need to enable these clocks, no need
to configure the rate.

This driver uses Generic Pinctrl framework and is compatible with
the Linux driver for ast2500: it uses the same device tree
configuration.
Not all pins are supported by the driver at the moment, so it actually
compatible with ast2400. In general, however, there are differences that
in the future would be easier to maintain separately.
