1. Ugly implicit 'priv' argument here. :-(
Please just do something like:
#define MWL8K_A2H_INT_RX_READY (1 << 1)
#define MWL8K_A2H_INT_TX_DONE (1 << 0)
+
+/* Misc registers */
+#define MWL8K_HW_TIMER_REGISTER 0x0000a600
#define MWL8K_A2H_EVENTS (MWL8K_A2H_INT_DUMMY | \
MWL8K_A2H_INT_CHNL_SWITCHED | \
and then just use it as ioread32(priv->regs + MWL8K_HW_TIMER_REGISTER).
2. Does this register exist on 8687/superfly3, or is it SJ only?
