From: Jérôme Pouiller <jerome.pouiller@silabs.com> Add Silabs SDIO ID to sdio_ids.h. Note that the values used by Silabs are uncommon. A driver cannot fully rely on the SDIO PnP. It should also check if the device is declared in the DT. Signed-off-by: Jérôme Pouiller <jerome.pouiller@silabs.com> --- include/linux/mmc/sdio_ids.h | 7 +++++++ 1 file changed, 7 insertions(+)
