Subject: [PATCH 3/3] ARM64: dts: amlogic: enable sd_emmc_b on all Tronsmart Vega S95 devices
Date: Sat, 25 Jun 2016 18:34:46 +0200	[thread overview]
Message-ID: <20160625163446.7245-4-martin.blumenstingl@googlemail.com> (raw)
In-Reply-To: <20160625163446.7245-1-martin.blumenstingl@googlemail.com>

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).
