I did this patch on top of your series which should fix the
issue on all omap4 boards too. Tested on omap4panda and
omap4sdp boards.
Can you test something with these patches?
1. Build the gpio-twl4030.c as a module, but with HSMMC support built in
2. Boot on the 4430SDP
twl4030 gpio is used for card detect on OMAP3, so I tried this
on my Beagle instead of 4430SDP.
The kernel boots up but does not detect/enumerate the mmc card.
3. Load the gpio-twl4030 module
I was expecting this to now detect the card, but I instead got
this error which seems to tell gpio-twl4030 has problems
when built/used as a module, outside of the mmc issues.
# insmod gpio-twl4030.ko
[ 16.217864] twl4030_gpio twl4030_gpio: can't dispatch IRQs from modules
[ 16.242004] gpiochip_add: registered GPIOs 192 to 211 on device: twl4030
4. Remove the gpio-twl4030 module
5. Re-load the gpio-twl4030.ko module
and report back what you get. Thanks.
