Subject: [PATCH 060/129] mmc: sd: Fix SDR12 timing regression
|
|
|
|
commit dd8df17fe83483d7ea06ff229895e35a42071599 upstream.
|
|
|
|
This patch fixes a failure to recognize SD cards reported on a Dell
|
|
Vostro with O2 Micro SD card reader. Patch 49c468f ("mmc: sd: add
|
|
support for uhs bus speed mode selection") caused the problem, by
|
|
setting the SDHCI_CTRL_HISPD flag even for legacy timings.
