920d477264 dts: jedec,spi-nor: add support for deep-power-down specification
Provide information required to allow the driver to put the flash chip
into a deep power down mode.  This can reduce standby current by as
much as 90%.

f43bae38e8 dts: Use separate compatibles for Nordic SPI/SPIM/SPIS peripherals
This commit introduces separate "compatible" strings for DTS nodes
representing different types of Nordic SPI peripherals. Previously
"nordic,nrf-spi" was used for both SPI and SPIM. SPIS was already
handled separately.

Quite a few files need to be touched by this commit but the changes can
be divided into groups of related or very similar ones, distinguishable
by the initial part of the path to the modified file:

* dts/bindings/spi/
  new binding for "nordic,nrf-spim" is added and common fields for all
  3 types of Nordic SPI peripherals are extracted to a shared file

* dts/arm/nordic/
  "compatible" properties in spiX nodes are updated (when there is no
  choice as only one type of SPI peripheral is available) or replaced
  with a comment pointing out that the proper type of peripheral needs
  to be picked at some upper layer

* drivers/spi/
  spi_nrfx_spim driver is updated with the new form of macros generated
  from dts

* boards/
  all spiX nodes in dts files for boards equipped with an nRF chip are
  updated with the proper "compatible" property, according to the type
  of SPI peripheral that is currently selected for the board by the
  corresponding Kconfig choice option (SPI_x_NRF_SPI*)

dd4c57d564 dts: Use separate compatibles for Nordic TWI/TWIM/TWIS peripherals
This commit introduces separate "compatible" strings for dts nodes
representing different types of Nordic TWI peripherals. Previously
"nordic,nrf-i2c" was used for both TWI and TWIM, and TWIS was not
supported.

Quite a few files need to be touched by this commit but the changes can
be divided into groups of related or very similar ones, distinguishable
by the initial part of the path to the modified file:

* dts/bindings/i2c/
  new bindings for "nordic,nrf-twim" and "nordic,nrf-twis" are added
  and the one for "nordic,nrf-i2s" is renamed to "nordic,nrf-twi",
  common fields for all these bindings are extracted to a shared file

* dts/arm/nordic/
  "compatible" properties in i2cX nodes are updated (when there is no
  choice as only one type of TWI peripheral is available) or replaced
  with a comment pointing out that the proper type of peripheral needs
  to be picked at some upper layer

* drivers/i2c/
  both flavors of i2c_nrfx drivers are updated with the new names of
  macros generated from dts

* boards/
  all i2cX nodes in dts files for boards equipped with an nRF chip are
  updated with the proper "compatible" property, according to the type
  of TWI peripheral that is currently selected for the board by the
  corresponding Kconfig choice option (I2C_x_NRF_TWI*)

fa10a9640b dts/spi-nor: use bytestring for JEDEC ID
This was always intended to be a bytestring rather than an array, but
full support was missing.  Since that has been addressed switch it to
the preferred format.

ea86f9a117 boards/particle_*: correct spi flash description
Particle released documentation with a pre-release flash chip.  Correct
the name to the actual as-sold device, and add the corresponding size
property as well as the has-be32k property.  Also add an alias so we
can set partitions externally.

6bdb1b8b60 boards: arm: particle_*: uncomment cs-gpios in spi assignments
At the time these overlays were created the author was unclear on how to
correctly represent SPI chip selects on a target where the peripheral
does not control that signal.  As such the pin assignment was present
only as documentation.

Enlightenment was subsequently achieved and the cs-gpios property should
be properly defined.

Note that the mesh feather does not define a chip select to be used with
the spi1 peripheral.

This conforms to the standard layout implied by adding BOARD_DIR to
DTS_ROOTS.
