[PATCH v4 1/4] omap4 hsmmc: Adding card detect support for MMC1

[Tony Lindgren]

* kishore kadiyala <kishore.kadiyala at ti.com> [100924 10:05]:
> Adding card detect callback function and card detect configuration
> function for MMC1 Controller on OMAP4.
> 
> Card detect configuration function does initial configuration of the
> MMC Control & PullUp-PullDown registers of Phoenix.
> 
> For MMC1 Controller, card detect interrupt source is
> twl6030 which is non-gpio. The card detect call back function provides
> card present/absent status by reading MMC Control register present
> on twl6030.
> 
> Since OMAP4 doesn't use any GPIO line as used in OMAP3 for card detect,
> the suspend/resume initialization which was done in omap_hsmmc_gpio_init
> previously is moved to the probe thus making it generic for both OMAP3 & OMAP4.

Looks like this patch should be sent to Samuel Ortiz as it's mostly
mfd related.
