[PATCH v2 1/3] ARM64: dts: amlogic: SD card support for all Tronsmart Vega S95 devices
From: Martin Blumenstingl <hidden>

Subsystem:
arm/amlogic meson soc support, the rest · Maintainers:
Neil Armstrong, Kevin Hilman, Linus Torvalds
sd_emmc_b is routed to the SD-card. Unlike p20x there is no GPIO regulator, meaning it only supports 3.3V (which seems to be hard-wired).
