[PATCH v2] dt-bindings: firmware: brcm,kona-smc: convert to YAML

From: Stanislav Jakubek
Date: Mon May 08 2023 - 04:11:06 EST


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)

Changes in V2:
- move to firmware subdirectory (Krzysztof)
- drop deprecated compatibles (Krzysztof)
- adjusted commit message to reflect the above changes
