  16 * These flags are used to describe power management features that
  17 * some cards (typically SDIO cards) might wish to benefit from when
  18 * the host system is being suspended.  There are several layers of
  19 * abstractions involved, from the host controller driver, to the MMC core
  20 * code, to the SDIO core code, to finally get to the actual SDIO function
  21 * driver.  This file is therefore used for common definitions shared across
  22 * all those layers.
