+
+    ath9k_hw: fix PLL clock initialization for newer SoC
+    
+    On AR934x and newer SoC devices, the layout of the AR_RTC_PLL_CONTROL
+    register changed. This currently breaks at least 5/10 MHz operation.
+    AR933x uses the old layout.
+    
+    It might also have been causing other stability issues because of the
+    different location of the PLL_BYPASS bit which needs to be set during
+    PLL clock initialization.
+    
+    This patch also removes more instances of hardcoded register values in
+    favor of properly computed ones with the PLL_BYPASS bit added.

+    ath9k_hw: reduce ANI spur immunity setting on HT40 extension channel
+    
+    The cycpwr_thr1 value needs to be lower on the extension channel than on
+    the control channel, similar to how the register settings are programmed
+    in the initvals.
+    
+    Also drop the unnecessary check for HT40 - this register can always be
+    written. This patch has been reported to improve HT40 stability and
+    throughput in some environments.
