In scripts as well as interactively, it's much nicer to be able to
refer to GPIOs via their names defined in the device tree property
"gpio-line-names", instead of the rather opaque names derived from the
bank name with a _xx suffix. E.g.
gpio read factory_reset FACTORY_RESET
if test $factory_reset = 1 ; then ...
versus
gpio read factory_reset gpio@481ac000_16
if test $factory_reset = 1 ; then ...
This is also consistent with the move on the linux/userspace side towards
using line names instead of legacy chip+offset or the even more legacy
global gpio numbering in sysfs.
As dev_read_stringlist_search() depends on both OF_CONTROL and
OF_LIBFDT (which matters for the SPL case), we need some .config
conditional. However, it only adds about ~50 bytes of code to U-Boot
proper, and dm_gpio_lookup_name() most often ends up being GC'ed for
SPL, thus adds no overhead there, so for now make it a hidden symbol
which is merely a convenient shorthand for
CONFIG_IS_ENABLED(OF_CONTROL) && CONFIG_IS_ENABLED(OF_LIBFDT).

new platforms gaining support:
* Initial support for SDM670 (similar to SDM845), SM6350, and SM7150
platforms is added
* USB and UART issues on MSM8916 are addressed (improving stability/
reliability)
* Firmware loading is implemented for the GENI serial engine, this is
used on some platforms to load firmware for i2c/spi/uart to work
Some additional patches like binman support for building MBN files still
need some additional work.

Qualcomm peripherals like UART, SPI, I2C, etc are all exposed under a
common GENI Serial Engine wrapper device. Replace the stub driver we use
for this currently with a full-on misc device and implement support for
loading peripheral firmware.
Each of the peripherals has it's own protocol-specific firmware, this is
stored on the internal storage of the device with a well-known partition
type GUID.
To support this, GENI will bind peripherals in two stages. First the
ones that already have firmware loaded (such as the serial port) are
bound in the typical way. But devices that require firmware loading are
deferred until EVT_LAST_STAGE_INIT. At this point we can be sure that
the storage device is available, so we load the firmware and then bind
and probe the remaining children.
Child devices are expected to determine if firmware loading is necessary
and call qcom_geni_load_firmware().
Since Linux currently doesn't support loading firmware (and firmware may
not be available), we probe all GENI peripherals to ensure that they
always load firmware if necessary.

NXP i.MX SoCs are available in different temperature grades. By default,
device-tree contains only thermal trips for consumer grade parts. On the
other hand, part temp grade fuse can be used to determine thermal trip
points. We already do this in imx_tmu_bind() function. Now, factor out
this functionality to a standalone function imx_tmu_set_trips() and use

Some boards have SD card connectors where the power rail cannot be switched
off by the driver. However there are various circumstances when a card
might be re-initialized, such as after system resume, warm re-boot, or
error handling. However, a UHS card will continue to use 1.8V signaling
unless it is power cycled.
If the card has not been power cycled, it may still be using 1.8V
signaling. According to the SD spec., the Bus Speed Mode (function group 1)
bits 2 to 4 are zero if the card is initialized at 3.3V signal level. Thus
they can be used to determine if the card has already switched to 1.8V
signaling. Detect that situation and try to initialize a UHS-I (1.8V)
transfer mode.

The functions s2mps11_{buck,ldo}_mode use the s2mps11_{buck,ldo}_modes
arrays directly in order to extract the mode of a certain register.
This approach does not allow similar devices of other variants (which
may support a different set of modes) to work with the same driver.
Instead of using these arrays hardcoded, extract them from the device's
uclass platform data. Now the responsibility of setting these arrays
properly is done by functions s2mps11_{buck,ldo}_probe, by implementing
a switch-case block which can support modes of multiple variants if and
when added.

In the Linux kernel driver, all information related to LDO and BUCK
regulators are stored in descriptive arrays. This also allows multiple
variants to be supported by the same driver.
Define a struct sec_regulator_desc which holds all values required by a
regulator. Create an array of said struct containing all regulators. The
descriptors are designed to follow a style similar to what's seen in the
Linux driver, so comparing one with the other is simple.
In functions such as s2mps11_{buck,ldo}_{val,mode} these values are to
be used, make necessary modifications to pull them from the descriptors.
Since multiple variants have varying descriptors, select them from
within a switch-case block.
Functions s2mps11_{buck,ldo}_{volt2hex,hex2volt} and arrays
s2mps11_buck_{ctrl,out} are phased out as the calculations are now
hardcoded in descriptors, thusly, it reduces clutter and enhances
readability.
Two macros in s2mps11.h, S2MPS11_LDO_NUM and S2MPS11_BUCK_NUM are
removed as they are no longer being used.

Note that here it seems that Exynos7 DW MMC is perfectly compatible with
Exynos7870 DW MMC. It's not always true, especially in SDIO cards where
data from a 64-bit FIFO is read in two 32-bit halves [1]. Since SDIO
isn't used or implemented here, it's oblivious. But upstream's schema
considers that quirk, so that compatible is followed.

SD UHS mode is already supported by the Exynos DW-MMC driver in mainline
Linux. Using that as reference, add support in the U-Boot driver.
The maximum frequency was capped to 200000000, increase it to 208000000,
which is the required frequency for UHS_SDR104, which has the highest
frequency of all UHS modes. Moreover, add UHS_CAPS to host capailities.
These changes allow both host and card to recognize support for all UHS
modes.
SDR104, SDR50, and DDR50 have their own CLKSEL timing values, which
requires the CIU div value to be set in bits 18:16. Move the function
exynos_dwmci_clksel() below exynos_dwmmc_get_ciu_div() so that the
latter is accessible from the former, and add cases for said timing
