Changes in v3: - Added tags. - Drop unnecessary initialization of variable. - Rename adapter->is_adapter_up to adapter->is_up in the mwifiex driver. Changes in v2: - Add adaptations to the mwifiex driver. - Keep existing synchronous reset behaviour if the SDIO card has a single func driver. The cover-letter from v2: It has turned out that it's not a good idea to try to power cycle and to re-initialize the SDIO card, as currently done through mmc_hw_reset(). This because there may be multiple SDIO funcs attached to the same SDIO card and some of the others that didn't execute the call to mmc_hw_reset(), may then simply experience an undefined behaviour. The following patches in this series attempts to address this problem, by reworking the mmc_hw_reset() behaviour for SDIO and by adopting the Marvel mwifiex driver to these changes. Note that, I don't have the HW at hand so the the code has only compile tested. Test on HW is greatly appreciated!
