Subject: [PATCH 1/2] riscv: dts: unleashed: Add gpio card detect to mmc-spi-slot
Date: Wed, 16 Jun 2021 15:46:44 +0800 [thread overview]
Message-ID: <20210616074645.429578-1-bmeng.cn@gmail.com> (raw)
From: Bin Meng <bin.meng@windriver.com>
Per HiFive Unleashed schematics, the card detect signal of the
micro SD card is connected to gpio pin #11, which should be
reflected in the DT via the <gpios> property, as described in
Documentation/devicetree/bindings/mmc/mmc-spi-slot.txt.
