Hello Luciano, I use omap3evm board with wl1271 extension module. Current version of wl1271 driver works fine on upstream kernel and (with minor modifications resulting from older mac80211) on 2.6.32 kernel with integrated SDIO runtime PM patches from Ohad Ben-Cohen. In the current kernel runtime PM support is always enabled for omap2plus boards. However this is not the case for the earlier kernels. Besides, on some other boards there might be no gpio pin to control power supply of wl1271 card. So the question is: what is the proper use of wl1271 driver in the case when wl1271 card is powered all the time ? In a simple experiment I removed all pm_runtime functions from wl1271_sdio.c and removed MMC_CAP_POWER_OFF_CARD flag from mmc slot settings in board file. However I can't do ifdown/ifup procedure properly: root@omap3evm_minimal:~# ifconfig wlan0 down root@omap3evm_minimal:~# ifconfig wlan0 up [ 55.313201] wl1271: ERROR timeout waiting for the hardware to complete initialization [ 58.813964] wl1271: ERROR timeout waiting for the hardware to complete initialization [ 60.648651] wl1271: ERROR sdio read failed (-110) [ 60.653686] wl1271: ERROR sdio write failed (-110) [ 62.057067] wl1271: ERROR sdio read failed (-110) [ 62.062072] wl1271: ERROR chip id doesn't match after firmware boot [ 62.068786] wl1271: ERROR firmware boot failed despite 3 retries ifconfig: SIOCSIFFLAGS: Input/output error It looks like init procedure of wl1271 card can not be done twice without powering off wl1271 card.
