Hi Hauke
u32 bcma_chipco_gpio_in(struct bcma_drv_cc *cc, u32 mask)
{
- return bcma_cc_read32(cc, BCMA_CC_GPIOIN)& mask;
+ unsigned long flags;
+ u32 res;
+
+ spin_lock_irqsave(&cc->gpio_lock, flags);
+ res = bcma_cc_read32(cc, BCMA_CC_GPIOIN)& mask;
+ spin_unlock_irqrestore(&cc->gpio_lock, flags);
+
+ return res;
}
Hi Hauke, do you need to lock the read access ?if bcma_cc_read32() is a simple memory read wrapper you most likely wont need the lock
