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. - - Reported-by: Lorenzo Bianconi <lorenzo.bianconi83@gmail.com> - Signed-off-by: Felix Fietkau <nbd@openwrt.org> - -commit b6d1f51cd8bdc9d952147a960fbf1f261d8e4188 -Author: Felix Fietkau <nbd@openwrt.org> -Date: Mon Sep 8 18:35:08 2014 +0200 - - 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.
