Subject: [PATCH 2/2] arm64: dts: renesas: salvator: Switch eMMC bus to 1V8
Date: Sat, 27 Oct 2018 18:34:10 +0200 [thread overview]
Message-ID: <20181027163410.7417-2-marek.vasut+renesas@gmail.com> (raw)
In-Reply-To: <20181027163410.7417-1-marek.vasut+renesas@gmail.com>
The eMMC card has two supplies, VCC and VCCQ. The VCC supplies the NAND
array and the VCCQ supplies the bus. On this particular board, the VCC is
connected to 3.3V rail, while the VCCQ is connected to 1.8V rail. Adjust
the pinmux to match the bus, which is always operating in 1.8V mode.
