Dear all,
i am trying to have working this module with kernel 3.10 over
sdio, 4 lines, high speed, on a imx6q.
The bcm43362 CHIP_ID is still missing in kernel 3.10 so i merged
some small parts of 3.14 wifi drivers into 3.10.
Actually, seems this module does not reply to the SDIO probing
command
mkfs.ext4 will erase the entire partition on the eMMC device before
writing the actual filesystem. The number of blocks erased on each
erase eMMC command is determined at run time based on the max erase
or trim time specified by the EXT_CSD in the eMMC device and the max eMMC
command timeout suppor

We really don't want to get a card detect interrupt during probe time
since it can confuse things. Let's disable the card detect interrupt
until we're in a really good place: the end of probe. Let's also
simply avoid enabling the card detect interrupt if it's not used.
It appears that (at least
It's unlikely that this is really needed on any single-slot systems
where we disable card detects until the end of probe, but it still
seems safer to check to make sure that a slot has been initted before
we try to dereference it to find the SDIO interrupt mask.
