Subject: [PATCH 1/1] arm64: dts: freescale: tqma8mpql: Fix vqmmc-supply
Date: Tue, 7 Jan 2025 16:03:09 +0100 [thread overview]
Message-ID: <20250107150310.996683-1-alexander.stein@ew.tq-group.com> (raw)
eMMC is supplied by BUCK5 rail. Use the actual regulator instead of
a virtual fixed regulator.
Fixes: 418d1d840e421 ("arm64: dts: freescale: add initial device tree for TQMa8MPQL with i.MX8MP")
