Subject: [PATCH 5/5] ARM: dts: imx6ull-tarragon-common: Fix vmmc supply
Date: Sun,  4 Oct 2026 16:01:23 +0200	[thread overview]
Message-ID: <20261004140123.46461-6-wahrenst@gmx.net> (raw)
In-Reply-To: <20261004140123.46461-1-wahrenst@gmx.net>

reg_dcdc_3v3 and sw2_reg actually represent the same physical regulator,
while the former one is used as vmmc supply for the eMMC. So use the proper
regulator of the PMIC instead, drop the bogus fixed regulator and keep
the better node reference.

Fixes: 5e4f393ccbf0 ("ARM: dts: imx6ull: Add chargebyte Tarragon support")
