[PATCH 0/6] Fix issues around twl4030-gpio used as a module

[Rajendra Nayak]

Hi Tony,

This series is based on top of 'hsmmc' branch in linux-omap
on top of commit '0e91c8ddf0e0932da59ec1d116e34049791b0e73' as
requested by you.

This mainly splits omap_hsmmc_late_init() into omap_hsmmc_deferred_add()
and omap_hsmmc_deferred_del() and adds .teardown hooks in all omap3 boards
to handle issues around multiple twl4030-gpio module insmod/unbind/bind
as reported by Russell.

In the process this series adds an api to unregister an
omap_device, makes mmc driver work with hotpluggable devices
and also removes 'deferred' flag for a few mmc devices on some
boards which are not really dependent on twl4030-gpio for card
detect as reported by Igor.

I have tested this series on omap3 beagle, with twl4030-gpio built
in, as well as twl4030-gpio built as a module and by doing multiple
insmod/unbind/bind sequence. I have tested card-detect to work fine
on beagle too.

regards,
Rajendra

  ARM: OMAP: omap_device: Add omap_device_unregister()
  mmc: omap_hsmmc: Make the driver support hotpluggable devices
  mmc: omap_hsmmc: If probe fails, give our error messages
  ARM: OMAP3: Make only mmc devices using gpio_cd as deferred
  ARM: OMAP3: Modify omap_hsmmc_late_init to handle deleting mmc
    devices
  ARM: OMAP3: Use .teardown of twl4030-gpio to clean board requests
