For some unknown reason ELP_CTRL can't be accesed using sdio_memcpy_* functions (any attemts to do so result in timeouts): wl1251: ERROR sdio write failed (-110) wl1251: ERROR sdio read failed (-110) wl1251: WARNING WLAN not ready To fix this, add special IO functions for ELP_CTRL access that are using sdio_readb/sdio_writeb. Similar handling is done in TI reference driver from Android code drop.
