So this is now using both DT and pdata?
We want to use DT only, and get rid of pdata. Other than the
deferred probe, is there some other dependency remaining to
having to use the pdata also?
We are using pdata today mainly for the platform function pointers
that get passed for MMC, which can never be passed from DT.
The omap_mmc_platform_data structure today has '17' function pointers.
Most might be sparingly used, nevertheless, its an awfully large number.
Here's the list...
---------
int (*switch_slot)(struct device *dev, int slot);
int (*init)(struct device *dev);
void (*cleanup)(struct device *dev);
void (*shutdown)(struct device *dev);
int (*suspend)(struct device *dev, int slot);
int (*resume)(struct device *dev, int slot);
int (*get_context_loss_count)(struct device *dev);
per-slot functions
int (*set_bus_mode)(struct device *dev, int slot, int bus_mode);
int (*set_power)(struct device *dev, int slot,
int power_on, int vdd);
int (*get_ro)(struct device *dev, int slot);
int (*set_sleep)(struct device *dev, int slot, int sleep,
int vdd, int cardsleep);
void (*remux)(struct device *dev, int slot, int power_on);
void (*before_set_reg)(struct device *dev, int slot,
int power_on, int vdd);
void (*after_set_reg)(struct device *dev, int slot,
int power_on, int vdd);
void (*init_card)(struct mmc_card *card);
int (*get_cover_state)(struct device *dev, int slot);
int (*card_detect)(struct device *dev, int slot);
