-Subject: [PATCH] mmc: Add SDIO function devicetree subnode parsing
-
-This adds SDIO devicetree subnode parsing to the mmc core. While
-SDIO devices are runtime probable they sometimes need nonprobable
-additional information on embedded systems, like an additional gpio
-interrupt or a clock. This patch makes it possible to supply this
-information from the devicetree. SDIO drivers will find a pointer
-to the devicenode in their devices of_node pointer.
