   4 Subject: [PATCH] mmc: xenon_sdhci: Add missing common host capabilities
   5
   6 Use mmc_of_parse() to set the common host properties. That includes
   7 "bus-width", so parsing it can be removed from the driver.
   8
   9 But more importantly, "non-removable" is now respected, which fixes
  10 the usage of eMMC.
