Add support for dumping a few of the clocks used on Qualcomm platforms.
Naming the Global PLL's, Root Clock Generators, and gate clocks.
This helps a lot with platform bringup and feature enablement by making
it easy to sanity check that the clocks are programmed correctly.
== Usage ==
Enable CONFIG_CMD_CLK and "#define LOG_DEBUG" at the top of
qcom-<soc>.c.
The "clk dump" command should print the states of all the gates, GPLLs
and RCGs for your SoC.
== Glossary ==
RCG: Root Clock Generator
* Takes in some fairly arbitrary high freq clock (configurable clock
source and options for taking just even pulses and other things)
* Output frequency = input_freq * (m/n) * (1/d) where m/n are arbitrary
8 or 16-bit values (depending on the RCG), and d is a number (with
support for .5 offsets).
GPLL: Global Phase Locked Loop
* Crystal as input
* integer multiplier + exponent part (2^-40)
Gate: Simple on/off clock
* Put between RCGs and the peripherals they power
* Required to allow for correct power sequencing
If you do the maths manually using the equations from "clk dump", the
numbers should roughly line up by they're likely to be out by a handful
of MHz. They output is formatted so that it can be pasted directly into
the python interpreter.

This reverts commit 19f000b72b.
The bug in writing was caused by a long-standing error in the SPMI
driver which has since been fixed - c2de620d64 ("spmi: msm: fix
version 5 support"). We can safely enable writing GPIO configuration
now.

Add pinctrl and GPIO driver for SM8150. Driver code is based on the
similar U-Boot drivers. All constants are taken from the corresponding
Linux driver. This drivers differs from the similar U-Boot drivers,
because SM8150 SoC have different function IDs for the same functions
on different pins.

Allow MMC init when clock support is not enabled in a particular phase.
Refactor the setting of priv->emmc_clk so it is a bit clearer.

When MMC booting fails it is sometimes hard to figure out what went
wrong as there is no error code. It isn't even clear which MMC device
was chosen, since SPL can have its own numbering.
Add some debugging to help with this.

Separate BSS is current mandatory on armv8 but this is not useful for

Use an #ifdef to avoid using CONFIG_SPL_BSS_START_ADDR which is not

ADSP-SC5xx is a series of ARM-based DSPs.
This comprises the armv7 based SC57x, SC58x and SC594 series, and the
armv8 based SC598.
This patch series includes configurations, init code, and minimal DTs
to enable Analog Devices' evaluation boards for these SoCs to boot
through SPL and into U-Boot Proper, as well as devicetree schemas for
the added DTs.
This patch series depends on ("arm: Add Analog Devices SC5xx Machine

Moves common options between all SC5xx series boards to the ARCH_SC5XX
option instead of duplicating them.
Also, it was possible to select multiple of the SoC support options.
Given a U-Boot binary can only support a single platform, this moves
the SoC selection to a `choice`, making them mutually exclusive.
