From 7f67a45ee7c008c3d8e45fde6fa9c4287fb3bc9e Mon Sep 17 00:00:00 2001 From: Jacopo Mondi Date: Thu, 20 Jul 2023 13:18:34 +0200 Subject: [PATCH] overlays: Add overlay for the OV64A40 Arducam Camera Module Arducam have integrated an Omnivision OV64A40 with a ROHM BU64754 VCM with a Raspberry Pi compatible cable pinout. Provide an overlay to support the module. Also add support to the camera mux overlays.
