4 Subject: [PATCH 0770/1085] overlays: Add overlay for the OV64A40 Arducam
5 Camera Module
6
7 Arducam have integrated an Omnivision OV64A40 with a ROHM BU64754 VCM
8 with a Raspberry Pi compatible cable pinout.
9
10 Provide an overlay to support the module.
11
12 Also add support to the camera mux overlays.
