This is joint work with Kumar Gala (see signed-off-by).
Add helper macros which abstract the "true names" of each of the four
types of node identifier we intend to support (e.g. DT_ALIAS(),
DT_INST()).
These can be passed to a new DT_PROP() macro which can be used to read
the value of a devicetree property given a node identifier from one of
these four other macros, and the as-a-c-token name of the property.
Add other accessor macros and tests as well.
Add some convenience APIs for writing device drivers based on instance
numbers as well. Drivers can "#define DT_DRV_COMPAT driver_compatible"
at the top of the file, then utilize these DT_INST_* macros to access
various property defines.
For example, the uart_sifive driver can do:
#define DT_DRV_COMPAT sifive_uart0
Then use DT_INST macros like:
.port = DT_INST_REG_ADDR(0),
.sys_clk_freq = DT_INST_PROP(0, clock_frequency),
For convenience working with specific hardware, also add:
<devicetree/gpio.h>

The `xlnx,ttcps` binding, despite having the file name of
`xlnx,ttcps.yaml`, had the compatible property of `cdns,ttc`.
While it is true that the Xilinx ZynqMP platform embeds the Cadence
Triple Timer Counter (TTC) IP core, its TTC differs from the original
Cadence core in that it implements 32-bit counters, instead of the
16-bit counters defined in the original; hence, the Xilinx variant is
not compatible with the original Cadence version and should be treated
as a different device.
This commit changes the `xlnx,ttcps.yaml` compatible property to

This adds support for the Espressif ESP8266 and ESP32 devices to be used
as peripherals on a UART.
There are two main AT command versions that can be selected, 1.7 and
2.0. Since they behave a bit different it is important to select the
one that matches the used in the firmware on your device.
When downloading large amounts of data it is highly recommended to
enable CONFIG_ESP_PASSIVE_TCP and flow control on the UART so that
data is not lost due to UART speed or receive buffer size.
Currently unsupported:
- Changing UDP endpoint with a sendto()
- Bind to a specific local port
- Server socket operations, ie listen() and accept()

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.

Also revise the documentation to note that the jedec,spi-nor
