   4 Subject: [PATCH 013/174] sdhci-bcm2708: add additional quirks
   5
   6 Some additional quirks are needed for correct operation.
   7 There's no SDHCI capabilities register documented, and it always reads
   8 zero, so add SDHCI_QUIRK_MISSING_CAPS. Apparently
   9 SDHCI_QUIRK_NO_HISPD_BIT is needed for many cards to work correctly in
  10 high-speed mode, so add it as well.
