[PATCH v1 1/1] arm64: dts: imx8mp-var-dart-sonata: Fix Sonata SD I/O supply

[Stefano Radaelli]

From: Stefano Radaelli <stefano.r@variscite.com>

LDO5 powers the USDHC2 I/O rail on DART-MX8M-PLUS.
Without a regulator consumer, the kernel disables LDO5 during late init,
which removes the SD card and causes filesystem I/O errors.

Reference LDO5 as the Sonata USDHC2 VQMMC supply, so the regulator
remains enabled while the SD interface is active.
