From: Mohammed Shafi Shajakhan Date: Fri, 13 May 2011 15:00:56 +0000 (+0530) Subject: ath9k_hw: define antenna diversity group X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=8afbcc8bfb549a522298fa4a31ee5155c2b5f7a0;p=openwrt%2Fstaging%2Fblogic.git ath9k_hw: define antenna diversity group AR9285 belongs to diversity group 0 and AR9485 belongs to diversity group 2. Based on the diversity group we configure certain antenna diversity paramaters such as lna1_lna2_delta and fast diversity bias values. For AR9485 we have some gain table parameter which selects the gain table 0/1 for main and alternate antenna Cc: Gabriel Tseng Cc: Senthilkumar Balasubramanian Signed-off-by: Mohammed Shafi Shajakhan Signed-off-by: John W.
