From 3ca8d1ec9a5374177b3f93313ac6f3e10cd3b113 Mon Sep 17 00:00:00 2001 From: Chaitanya Sabnis Date: Tue, 5 May 2026 15:38:54 +0530 Subject: [PATCH] dt-bindings: i2c: convert axxia i2c to dt-schema Convert the LSI Axxia I2C Controller bindings from legacy text format to modern dt-schema (YAML). During the conversion, the obsolete `device_type = "i2c"` property was dropped from the example, as it is deprecated and not utilized by the driver. The `clock-names` property is enforced as required matching the driver probe behavior. The example node address was also updated to a standard 32-bit address.
