Subject: [PATCH v12 12/15] mmc: sdhci-cadence: Support device specific init during probe
Move struct sdhci_pltfm_data under new struct sdhci_cdns_drv_data.
Add an init() into sdhci_cdns_drv_data for platform specific device
initialization in the device probe which is not used for existing devices.
Signed-off-by: Brad Larson <blarson@....com>
Acked-by: Adrian Hunter <adrian.hunter@...el.com>

v10 changes:
- New patch to provide for platform specific init() with no change
to existing designs.
