+Subject: [RFC 01/12] ath9k: introduce bus specific DMA routines
+
+In the AR913x SoCs, the WMAC devices are connected to the CPU through
+the internal AHB bus instead of PCI. We first patch ath9k driver to use
+replaceable DMA routines, so we can use different code for the AHB bus.

+Subject: [RFC 08/12] ath9k: get EEPROM contents from platform data on AHB bus
+
+On the AR913x SOCs we have to provide EEPROM contents via platform_data,
+because accessing the flash via MMIO is not safe. Additionally different
+boards may store the radio calibration data at different locations.

+Subject: [RFC 11/12] ath9k: fix ar5416Addac_9100 values
+
+Writing the register at offset 0x98c4 causes a deadlock on the AR913x
+SoCs. Although i don't have detailed knowledge about these registers, but if i
+change the register offset according to the 'ar5416Addac' table, it
+works. Additionally there is no reference to the 0x98c4 elsewhere.

+Subject: [RFC 12/12] ath9k: fix null pointer dereference in ani monitor code
+
+In 'ath9k_ani_reset' the 'ahp->ah_curani' will be initialized only
+if 'DO_ANI(ah)' true. In 'ath9k_hw_ani_monitor' we are using 'ahp->ah_curani'
+unconditionally, and it will cause a NULL pointer dereference on AR9100.
