| Subject: riscv: dts: unmatched: Add gpio card detect to mmc-spi-slot |
| |
| From: Bin Meng <bin.meng@windriver.com> |
| |
| commit 298d03c2d7f1b5daacb6d4f4053fd3d677d67087 upstream. |
| |
| Per HiFive Unmatched schematics, the card detect signal of the |
| micro SD card is connected to gpio pin #15, which should be |
| reflected in the DT via the <gpios> property, as described in |
| Documentation/devicetree/bindings/mmc/mmc-spi-slot.txt. |
