From 55e52d055393f11ba0193975d3db87af36f4b273 Mon Sep 17 00:00:00 2001 From: Johan Hovold johan+linaro@kernel.org Date: Fri, 14 Mar 2025 15:54:40 +0100 Subject: [PATCH] arm64: dts: qcom: x1e78100-t14s: fix missing HID supplies

Add the missing HID supplies to avoid relying on other consumers to keep them on.

This also avoids the following warnings on boot:

i2c_hid_of 0-0010: supply vdd not found, using dummy regulator i2c_hid_of 0-0010: supply vddl not found, using dummy regulator i2c_hid_of 1-0015: supply vdd not found, using dummy regulator i2c_hid_of 1-002c: supply vdd not found, using dummy regulator i2c_hid_of 1-0015: supply vddl not found, using dummy regulator i2c_hid_of 1-002c: supply vddl not found, using dummy regulator i2c_hid_of 1-003a: supply vdd not found, using dummy regulator i2c_hid_of 1-003a: supply vddl not found, using dummy regulator

Note that VCC3B is also used for things like the modem which are not yet described so mark the regulator as always-on for now.
