From 6c4b960981ddc676cecd929dd76d6e01bc5c424b Mon Sep 17 00:00:00 2001 From: Erikas Bitovtas Date: Wed, 25 Feb 2026 16:43:24 +0200 Subject: [PATCH] arm64: dts: qcom: msm8939-asus-z00t: add ambient light and proximity sensor This device uses Capella CM36686 as its ambient light and proximity sensor. It is fully compatible with Vishay VCNL4040. Downstream device tree reports Capella CM36283, but upon probe, a device ID for CM36686 is actually found. This commit adds support for Capella CM36686 ambient light and proximity sensor.
