This is my attempt to make SDIO interfaced TI WL1251 wifi chip usable on mainline kernels. It's driver has already been merged several releases back, but the problem is current SDIO core can't detect the card because it's not following SDIO standards and does not have any required SDIO registers. Currenty attempting to use this chip only results in several pages of complains about invalid register data from SDIO core. WL1251 is used on various HTC devices and Pandora handheld at least. People wanting to use this are forced to use forked trees or patches. My solution to this problem is to add new MMC quirk that will tell SDIO core not to access any SDIO registers and rely on host's init_card callback instead, which is now responsible for filling card related structures for SDIO core to function. Patches 2 and 3 set up the card for pandora, similar method could be used for MSM too. Only patches 2,3 depend on each other, so patch 1 can be merged separately.
