[PATCH 0/3] omap_hsmmc: reuse mmc/slot-gpio functions

[Andreas Fenkart <afenkart@gmail.com>]

Hi Balaji,

I'm trying to reuse mmc_of_parse for parsing standard mmc features: 
- cd-gpios / wp-gpios
- bus-width 
- max-frequency
- keep-power-in-suspend
- enable-sdio-wakeup
- ti,non-removable, evtl.

Currently these are open-coded in of_get_hsmmc_pdata. I tried
removing them all from of_get_hsmmc_pdata and call mmc_of_parse
at the end of the probe function:

@@ -2241,8 +2264,6 @@ static int omap_hsmmc_probe(struct platform_device *pdev)
        omap_hsmmc_protect_card(host);
+       mmc_of_parse(host->mmc);
        mmc_add_host(mmc);

This should work transparently for most features except,
cd-gpios/wp-gpios. Pls can you have a look at the followup
patches? I tried an intermediate step mapping card detect /
read-only detect onto mmc/slot-gpio that are used by
mmc_of_parse. I don't have card detect/read-only detect pins, :-(

Do we still need cover_detect functionality or could it be merged
with card detect?

Another issue is 'ti,non-removable' which could be mappend to
'non-removable' if 'no_regulator_off_init' could be handled in a
different way.

        if (of_find_property(np, "ti,non-removable", NULL)) {      
                pdata->slots[0].nonremovable = true;                     
                pdata->slots[0].no_regulator_off_init = true;              
        }   

thanks,
Andreas
