[PATCH 3/8] dt-bindings: media: i2c: Add Samsung S5K3M3 image sensor

[Gaurav Suman via B4 Relay <devnull+gauravsuman007.gmail.com@kernel.org>]

From: Gaurav Suman <gauravsuman007@gmail.com>

Add bindings for the Samsung S5K3M3 (ISOCELL 3M3) 13MP sensor, used
as the wide camera of the LG G8x ThinQ.

This was written and tested with the help of an AI coding assistant
(Claude Opus 5.5, Anthropic); I reviewed the change and the results.

+title: Samsung S5K3M3 Image Sensor
+
+description:
+  Samsung S5K3M3 (ISOCELL 3M3) is a 13MP image sensor controlled over a
+  serial camera control bus. The driver supports 4160x3120 at 30 frames per
+  second, RAW10 over a 4-lane MIPI D-PHY interface.
