* MMC: dw_mmc: PIO mode fixesAndrey Panov2015-03-091-73/+56
| | | | | | | | | | Simplify PIO mode routines. Fix a bug when IO is possibly performed twice because of using old interrupt status. Support for slow-speed card writes. Signed-off-by: Andrey Panov <rockford@yandex.ru> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * of: make of_alias_get work on all types of DT pathsLucas Stach2015-03-041-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | of_alias_get assumed that a DT path is always the full node path, whic is not necessarily the case, as there are other valid path descriptions. All of them are handled by of_find_node_by_path. As there is already a preparsed list with all DT aliases that handles this case properly we can simply reuse that one.
