[PATCH v6 18/23] dt-bindings: media: imx258: Add alternate compatible strings

From: git
Date: Sun Jun 02 2024 - 16:24:43 EST


From: Dave Stevenson <dave.stevenson@xxxxxxxxxxxxxxx>

There are a number of variants of the imx258 modules that can not
be differentiated at runtime, so add compatible strings for the
PDAF variant.

IMX258 is a diagonal 5.867mm (Type 1/3.06) 13 Mega-pixel CMOS active pixel
type stacked image sensor with a square pixel array of size 4208 x 3120. It
is programmable through I2C interface. Image data is sent through MIPI
- CSI-2.
+ CSI-2. The sensor exists in two different models, a standard variant
+ (IMX258) and a variant with phase detection autofocus (IMX258-PDAF).
+ The camera module does not expose the model through registers, so the
