| Subject: [PATCH] ARM: dts: stm32: fix stm32mp157c-odyssey card detect pin |
| MIME-Version: 1.0 |
| Content-Type: text/plain; charset=UTF-8 |
| Content-Transfer-Encoding: 8bit |
| |
| The microSD card detect pin is physically connected to the MPU pin PI3. |
| The Device Tree configuration of the card detect pin was wrong—it was |
| set to pin PB7 instead. If such configuration was used, the kernel would |
| hang on “Waiting for root device” when booting from a microSD card. |
