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.
This driver does it automatically.

This checks if the DMA controller supports or not
the memory-to-memory transfers. For DMA Version1,
in the stm32f2xx, stm32f4xx, stm32f7xx series,
only DMA instance 2 is able to transfer mem-to-mem.
For other series, with DMA Version2, there is no such a limitation.

Johann Fischer pointed out that the driver for this sensor
(master/drivers/sensor/tmp116/tmp116.c) doesn't use GPIOs, in
https://github.com/zephyrproject-rtos/zephyr/pull/21605, though there
seems to be an ALERT pin from looking at the datasheet
(http://www.ti.com/lit/ds/symlink/tmp116.pdf).
Remove the unused property declaration.
I was originally just going to change a 'category: optional' to
'required: false' (and 'type: compound' to 'type: phandle-array').
Either solution is fine with me. Could keep the declaration if people
are planning to use it soon.

Currently most SPI NOR serial flash devices are accessed through the
spi-nor flash driver, but there are pending enhancements that will
access these devices through other driver implementations. Several of
the descriptive properties of the flash memories are common regardless
of the interface selected. Pull those out to a separate yaml file to
be included into the bindings for interface-specific node descriptions.
Also revise the documentation to note that the jedec,spi-nor
compatible depends on a commands set compatible with the Micron M25P80
serial nor flash; there is no JEDEC standard for these commands.
These devices do generally provide descriptive structures defined by
JESD216, but currently Zephyr doesn't make use of these structures.
The JEDEC CFI standard previously referenced in the description is not
relevant to these devices.

Add any useful information from 'title:' to the 'description:' strings

copy-pasted "this binding gives a ..." boilerplate.
Also clean some description strings up a bit.
Some other things could probably be cleaned up (replacing 'GPIO node'
with 'GPIO controller' on controllers for consistency, for example), but
I kept things close to the original to avoid accidentally messing up.

Signed-off-by: Maureen Helm <maureen.helm@nxp.com>
The GIC-400 driver currently only supports SPIs because the (32) offset
for the INTIDs is hard-coded in the driver. At the driver level there is
no really difference between PPIs and SPIs so we can easily extend the
driver to support PPIs as well.
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.
