I should be applying that soon after v4.17-rc1 is out and its dependencies merged. Can you please re-spin this patch then to apply on top of that?

The legacy mode uses the write protect and card detect but DT has not. This patch enables the pinmuxing and detection for WP and CD. Signed-off-by: Adam Ford <aford173@gmail.com>
