Erwan Gouriou 1755cf6582 dts/bindings: Add 'generation' directive on for 'compatible' property
Add 'generation: define' directive to 'compatible' property.
When existing for a type of device, move compatible property
description in device base structure (eg: i2c.yaml)

Diego Sueiro 9283ee7acc arch: i.MX add RDC peripheral permission setting for applications cores
This patch adds the RDC (Resource Domain Controller) peripheral
permissions settings for the i.MX applications cores (Cortex A9 on
i.MX6 and Cortex A7 on i.MX7).

This will enable both Linux (on application's core) and Zephyr (on M4
core) to share the peripherals and coexist.

The settings are defined at devicetree level and applied in the soc.c.

A complete solution should involve the SEMA4 to control the peripherals
access and prevent resource deadlocking and misusage.

Diego Sueiro ecc891b296 drivers: Fix asserts in i.MX UART Driver
After running some tests which enable assert macro I found some issues
with the i.MX UART configuration.

This patch configures the Tx Fifo Watermark and Modem Mode accordingly.

Maureen Helm 4433d9d3d2 dts: yaml: Align serial driver clocks bindings
The common uart.yaml defines an optional clocks property that can be
overridden by specific serial driver bindings to be required. The
description and generation attributes are duplicated.

This fixes build warnings:
extract_dts_includes.py: Merge of 'description': 'Clock gate control
	information'  overwrites 'Clock gate information'.
extract_dts_includes.py: Merge of 'generation': 'structures'  overwrites
	'define'.

And introduces a different build warning, which is intended behavior:
extract_dts_includes.py: Merge of 'category': 'required'  overwrites
	'optional'.

Diego Sueiro 346165b2e8 serial: Add imx uart driver shim
Adds a shim layer around the imx uart driver to adapt it to the Zephyr
serial interface.

Modem mode was introduce to control it as DCE and DTE and can be
configured in the device tree:
    modem-mode:
        type: int
        category: required
        description: Set the UART Port to modem mode 0 (dce) 1 (dte)
        generation: define

For now only the UART 2 was tested.
