[PATCH v3 0/3] wifi: iwlwifi: add Device Tree hardware integration information

[Avinash Bhatt]

Add Device Tree support for Intel Wi-Fi hardware integration information
on platforms that do not provide UEFI variables or ACPI methods.

Patch 1/3 adds the DT binding schema for the Intel iwlwifi compatible
node. Patches 2/3 and 3/3 add the driver infrastructure and integrate
DT as the lowest-priority fallback after UEFI and ACPI; they are
included for reference to show how the binding is consumed by the
driver and will be merged through the regular iwlwifi upstreaming
process, not through the DT tree.

Changes since v2:

Binding (patch 1/3):
  - Subject and title updated to describe the BE200 hardware
  - Revision header cell removed from all properties; each property is
    now a scalar uint32 or plain fixed-size array
  - intel,wrds: reduced to 49 cells (mode word + 4x12 SAR values)
  - intel,uats: reduced to 338 bytes (26x13 country nibble matrix)
  - Removed allOf/items const: 0 constraints from all properties
  - intel,srd: changed from integer enum to string enum
    (active-scan/passive-scan/disabled)
  - Removed "reserved, must be 0" annotations; bits with no assigned
    meaning are not documented
  - Added allOf: $ref: /schemas/net/wireless/ieee80211.yaml#

Driver (patch 2/3):
  - Removed dsm_func_to_prop_name() and all IWL_DT_PROP_* defines;
    each property function now calls of_property_read_*() directly with
    the literal property string
  - Driver updated to match binding changes (no revision cells,
    string-based intel,srd, scalar uint32 DSM properties, 338-byte
    intel,uats)
  - Added iwl_dt_init() to validate DT node compatible at probe time;
    all DT reads gated on fwrt->dt_compatible
  - fw/dt.h now includes fw/runtime.h directly, making it self-contained

Fallback integration (patch 3/3):
  - No changes from v2
