I did test this patch series on h/w which is arm based MCU. From this patch wilc is not working properly. After downloading firmware, the firmware cannot start and it fails. I double check this patch and the previous one(14/20) which works fine. I cannot find the problem in this patch at the moment. I will see if I can find something, and I'd appreciate if you would help with it. regards, glen lee On 2015년 11월 11일 08:42, Arnd Bergmann wrote: > The wilc_hif_spi and wilc_hif_sdio structures are part of > the bus specific code, and the generic code should have no knowledge > of their addresses. > > This changes the code to reference them only from the bus > specific initialization code, which we can then use to split > up the driver into separate modules. > > Signed-off-by: Arnd Bergmann > --- > drivers/staging/wilc1000/linux_wlan.c | 4 ++- > drivers/staging/wilc1000/linux_wlan_sdio.c | 3 ++- > drivers/staging/wilc1000/linux_wlan_spi.c | 2 +- > drivers/staging/wilc1000/wilc_sdio.c | 35 +++++++++++++-------------- > drivers/staging/wilc1000/wilc_spi.c | 34 +++++++++++++------------- > drivers/staging/wilc1000/wilc_wfi_netdevice.h | 4 ++- > drivers/staging/wilc1000/wilc_wlan.c | 15 ++---------- > drivers/staging/wilc1000/wilc_wlan.h | 4 +-- > 8 files changed, 47 insertions(+), 54 deletions(-) > > diff --git a/drivers/staging/wilc1000/linux_wlan.c b/drivers/staging/wilc1000/linux_wlan.c > index e81e90678d0f..2fb1d97bded1 100644 > --- a/drivers/staging/wilc1000/linux_wlan.c > +++ b/drivers/staging/wilc1000/linux_wlan.c > @@ -1408,7 +1408,8 @@ void wilc_netdev_cleanup(struct wilc *wilc) > #endif > } > > -int wilc_netdev_init(struct wilc **wilc, struct device *dev, int io_type, int gpio) > +int wilc_netdev_init(struct wilc **wilc, struct device *dev, int io_type, > + int gpio, const struct wilc_hif_func *ops) > { > int i;
