| Subject: ARM: shmobile: Add SDHI devices for Koelsch DTS |
| |
| Add DT support for SDHI0, SDHI1 and SDHI2 on Koelsch. |
| |
| The board specific handling of CD and WP pins are |
| using GPIOs. SDHI0 and SDHI1 are hooked up to regular |
| SD connectors while SDHI2 is using micro-SD which |
| is lacking WP signal. |
