for embedded slots. Fail in the sdhci(4) initialization for slot type
shared, which is completely unsupported by this driver at the moment. [1]
For Intel eMMC controllers, taking the embedded slot type into account
obsoltes setting SDHCI_QUIRK_ALL_SLOTS_NON_REMOVABLE so remove these quirk
entries.
- Hide the 1.8 V VDD capability when the slot is detected as non-embedded,
as the SDHCI specification explicitly states that 1.8 V VDD is applicable
to embedded slots only. [2]
- Define some easy bits of the SDHCI specification v4.20. [3]
- Don't leak bus_dma(9) resources in failure paths of sdhci_init_slot().
