Subject: [PATCH v4] dt-bindings: firmware: brcm,kona-smc: convert to YAML
Convert Broadcom Kona family Secure Monitor bounce buffer bindings
to DT schema.
Changes during conversion:
- move from misc to firmware subdirectory
- add used, but previously undocumented SoC-specific compatibles
- drop deprecated compatibles (they've been deprecated for ~10 years)
Reviewed-by: Krzysztof Kozlowski <krzysztof.kozlowski@...aro.org>
Signed-off-by: Stanislav Jakubek <stano.jakubek@...il.com>

Changes in V4:
- collect Krzysztof's R-b
- rebase on next-20230616
Changes in V3:
- remove unnecessary oneOf (Krzysztof)
Changes in V2:
- move to firmware subdirectory (Krzysztof)
- drop deprecated compatibles (Krzysztof)
- adjusted commit message to reflect the above changes
