[PATCH 5/8] dt-bindings: media: i2c: Add Samsung S5KGD1 image sensor

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

From: Gaurav Suman <gauravsuman007@gmail.com>

Add bindings for the Samsung S5KGD1 (ISOCELL GD1) 32MP quad-Bayer
sensor, used as the front 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 S5KGD1 Image Sensor
+
+description:
+  Samsung S5KGD1 (ISOCELL GD1) is a 32MP image sensor with a quad-Bayer
+  (tetracell) colour filter array, controlled over a serial camera control
+  bus. The driver supports the 2x2 binned 3264x2448 mode at 30 frames per
+  second, RAW10 over a 4-lane MIPI D-PHY interface.
