Subject: [PATCH 1/4] arm64: dts: ti: k3-am64-tqma64xxl: add supply regulator for I2C devices
Date:   Thu, 28 Sep 2023 13:45:10 +0200
Message-Id: <d5991041263c96c798b94c0844a1550e28daa3b1.1695901360.git.matthias.schiffer@ew.tq-group.com>

Describes the hardware better, and avoids a few warnings during boot:

    lm75 0-004a: supply vs not found, using dummy regulator
    at24 0-0050: supply vcc not found, using dummy regulator
    at24 0-0054: supply vcc not found, using dummy regulator
