Converts the usdhc driver to the new gpio api. Updates the

Convert the GPIO based driver to the new GPIO API. (Only the
gpio_configure() call is affected).
Move configuration to DT where appropriate for both SPI and GPIO
drivers, only leaving the SPI vs. GPIO decision in Kconfig (in
addition to the basic enable for the driver.) Move some files around
to clean up as a result of this change.
led_ws2812 sample changes:
- make the pattern easier to look at by emitting less light
- use led_strip alias from DT to get strip device, allocate
appropriate struct led_rgb buffer, etc.
- move the pins around and remove 96b_carbon support (I have no board
to test with)
GPIO driver specific changes:
- str is required to write OUTSET/OUTCLR, not strb. The registers
are word-sized.
- the str[b] registers must all be in r0-r7, so "l" is the correct GCC
inline assembly constraint for both "base" and "pin"
SPI driver specific changes:
- match the GPIO driver in not supporting the update_channels API
method, which never made sense for this type of strip
- return -ENOMEM when the user tries to send more pixel data
than we have buffer space for instead of -EINVAL

ARM cores may have a per-core architected timer, which provides per-cpu
timers, attached to a GIC to deliver its per-processor interrupts via
PPIs. This is the most common case supported by QEMU in the virt
platform.
This patch introduces support for this timer abstracting the way the
timer registers are actually accessed. This is needed because different
architectures (for example ARMv7-R vs ARMv8-A) use different registers
and even the same architecture (ARMv8-A) can actually use different
timers (ELx physical timers vs ELx virtual timers).
So we introduce the common driver here but the actual SoC / architecture
/ board must provide the three helpers (arm_arch_timer_set_compare(),
arm_arch_timer_toggle(), arm_arch_timer_count()) using an header file
imported through the arch/cpu.h header file.

Most JEDEC NOR flash devices uses not only typical SPI mode
(MISO,MOSI,SCK and CS), but also QSPI mode (IO0,IO1,IO2,IO3,SCK and CS).
QSPI mode uses more data lines and as a result provide higher
throughput. If this were not enough, Nordic chips provide
hardware acceleration for read/write/erase functions, what
gives significant performance boost.
It does a lot of things "behind the scene", i.e when user has written
some data to the flash and would like to read them back, it has to wait
until the flash is ready by reading WIP bit in Status Register.

region but with different offsets for the distributor and CPU
interrupt control register sets. The GIC address mapping specified by
the current dts is that of an APU and does not apply to the PL390

Since the current Zephyr architecture cannot support AMP of Cortex-R

This commit relocates the device tree nodes that are not common between
RPU and APU to a separate dtsi file (zynqmp_rpu.dtsi).
When Cortex-A53 APU support is added in the future, an additional dtsi

That kind of description doesn't add any useful information, as it's

representation" was supposed to mean originally either.
Many bindings also put something that's closer to a description in the
title, because it's not clear what's expected or how the title is used.
In reality, the title isn't used anywhere. 'description:' on the other
hand shows up as a comment in the generated header.

The GIC-400 driver currently only supports SPIs because the (32) offset

This is useful if we want to add support for the ARM Generic Timers that
use INTIDs in the PPI range.
SPI interrupts are in the range [0-987]. PPI interrupts are in the range
[0-15].
This commit adds interrupt 'type' cell to the GIC device tree binding
and changes the 'irq' cell to use interrupt type-specific index, rather
than a linear IRQ number.
The 'type'+'irq (index)' combo is automatically fixed up into a linear
IRQ number by the scripts/dts/gen_defines.py script.

Add property for specifying the bus idle timeout for the NXP
i.MX/Kinetis LPI2C I2C controller.
Enabling the bus idle timeout helps the controller to recover from
e.g. EMC causing false clock pulses/spikes on the SCL line.
Without a timeout the LPI2C controller will assume that another bus
master took over the I2C bus and thus refuses to issue a I2C START
condition.

On power-on boot-ROM is mapped to address 0 in HSDK board.
Normally later when U-Boot gets started by boot-ROM we change mappings
so that real DDR is mapped to entire address space including 0:
https://elixir.bootlin.com/u-boot/latest/source/board/synopsys/hsdk/hsdk.c#L474
But if U-Boot is not started (which is controlled by the BIM dip-switch
on the board) boot-ROM remains mapped to 0, and essentially any attempt
to write to that location fails, thus we cannot upload contents of our
target Elf there even with JTAG.
The next logical option is to use beginning of the non-translated
memory region 0x8000_0000 which we typically use for loading
U-Boot & Linux kernel on ARC boards. But in case of HSDK
we have DCCM (Data Closely-Coupled MEmory - fast on-chip SRAM)
mapped there and since we cannot execute code from DCCM
we need to skip that region as well which gives us the next option
being 0x9000_0000 . That's because DCCM owns entire 256 MiB "aperture"
even though it may have much smaller size up-to 8 MiB.
We are mapping only 5 apertures because the last two
(0xe000_0000-0xffff_ffff) are used for peripherals and AXI.
