Subject: [PATCH 2/5] arm64: dts: ti: am68-sk: Fix power regulator hierarchy
Date: Tue, 1 Apr 2025 17:10:50 +0530	[thread overview]
Message-ID: <20250401114053.229534-3-y-abhilashchandra@ti.com> (raw)
In-Reply-To: <20250401114053.229534-1-y-abhilashchandra@ti.com>

Add a fixed regulator node for the LM61460 5V supply on the AM68 SK and
fix the vin-supply for the TLV71033 regulator on AM68-SK by updating it
from vsys_3v3 to vsys_5v0 to match the schematics.

AM68-SK schematics: https://www.ti.com/lit/zip/sprr463
Fixes: a266c180b398 ("arm64: dts: ti: k3-am68-sk: Add support for AM68 SK base board")
