| Subject: riscv: dts: unleashed: Add gpio card detect to mmc-spi-slot |
| |
| From: Bin Meng <bin.meng@windriver.com> |
| |
| commit 6331b8765cd0634a4e4cdcc1a6f1a74196616b94 upstream. |
| |
| 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. |
