Subject: [PATCH v1 02/10] dt-bindings: media: Add MT8188 ImgSys's LARB
This patch adds support for the MT8188 Image System's Local Arbiter
(LARB) in the device tree bindings. The LARB is a crucial component in
MediaTek's ImgSys architecture, responsible for managing memory access
and arbitration between various hardware modules.
