Maureen Helm 0d1beb2f9e boards: dts: Add mcr20a bindings and fix networking samples
Adds dts bindings for the mcr20a wireless transceiver. The frdm_k64f
board supports the mcr20a via an Arduino shield, therefore the dts node
is added to the board dts. The kw2xd is a SiP and thus the mcr20a dts
node is added to the soc dts.

The networking samples using prj_frdm_k64f_mcr20a.conf have been broken
since the refactoring of the mcux gpio driver to dts in commit
4e8f29f319. The sample is now fixed.

Maureen Helm d2d4cea02d dts: nxp_kinetis: Add spi bindings for kinetis dspi and update soc nodes
Adds dts spi bindings for the kinetis dspi controller, and updates the
k64, kw2xd, kw40z, kw41z dts nodes accordingly.

Updates the dts interrupt priorities to match the board defconfigs
(e.g., boards/arm/frdm_k64f/Kconfig.defconfig)

For k64, fixes an error in the spi1 interrupt number and adds a third
instance (spi2).

Maureen Helm 9cd36c7bd2 boards: dts: Add fxas21002 interrupt bindings and fix sensor sample
Adds dts bindings for the fxas21002 interrupt pins to all boards that
have this sensor.

The fxas21002 driver is currently only aware of one sensor interrupt
pin, therefore the routing of INT1 or INT2 to the driver is handled in
each board's dts.fixup.

The fxas21002 sample application has been broken since the refactoring
of the mcux gpio driver to dts in commit
4e8f29f319. The sample is now fixed.

Adds dts bindings for the fxos8700 interrupt pins to all boards that
have this sensor. The frdm_k64f and hexiwear_k64 connect both sensor
interrupt pins to the mcu, but the frdm_kw41z connects only one.

therefore the routing of INT1 or INT2 to the driver is handled in each

Erwan Gouriou 93d3a42776 scripts: extract_includes_dts: Remove usage of cell_string yaml attribute
'cell_string' yaml attribute has been introduced in order to
help enforcement of specific string during defines generation.
This adds complexity in understanding script behavior as a black
box and create additional dependency which is not strictly required.

For node specific generation functions (pinctrl and interrupts),
this could be replaced directly by an hardcoded version
(as everyone used the same 'cell_string' anyway).
For extract_cells functions, string could be replaced by extracted
property name. As a consequence, we're now able to generate defines
for properties refering to these controllers via phandle.
For instance, in following node
 	spbtle-rf@0 {
 		compatible = "st,spbtle-rf";
 		reg = <0>;
		reset-gpios = <&gpioa 8 0>;
 	};
We'll be able to generate:
 #define ST_STM32_SPI_...LE_RF_0_RESET_GPIOS_CONTROLLER	"GPIOA"
 #define ST_STM32_SPI_...PBTLE_RF_0_RESET_GPIOS_FLAGS_0		0
 #define ST_STM32_SPI_..._SPBTLE_RF_0_RESET_GPIOS_PIN_0		8

Only impact for this whole change is for NXP clocks which were the
only ones using 'cell_string' attribute with a value different than
the default one.

Same treatment is applied to 'inherits'.
