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.
