From 8564328d85f69121744d8337124857a2e726239b Mon Sep 17 00:00:00 2001 From: "Luis R. Rodriguez" Date: Mon, 19 Oct 2009 02:33:33 -0400 Subject: [PATCH] ath9k_hw: update register initialization/reset values for ar9271 This update the register initialization/reset values (aka initvals) for ar9271 based on the last recommended values on 2009-06-04 by our systems engineering team. The changes account for: * Supporting ar9271 1.0 and ar9271 1.1 together, the difference is bb_spectral_scan_ena, for 1.0 we'll set this to 0x1. * Ensuring we get the correct noise floor values -115 ~ -118 when we enable bb_enable_ant_div_lnadiv=0 and mc_tx_def_ant_sel=1. Previous to this we would get noise floor values in the range -50 ~ -80. To fix settings for the registers: - bb_ch1_xatten1_db - bb_ch1_xatten2_db - bb_ch1_xatten1_margin - bb_ch1_xatten2_margin - bb_ch1_gain_force - bb_ch1_xatten2_hyst_margin - bb_ch1_xatten1_hyst_margin - bb_ch1_max_oc_gain * 0x8120[2] mc_mic_new_location_enable is changed to 0x1. The MAC team suggest to set this value. * 0x9910[0] bb_spectral_scan_ena is changed to 0x0. For ar9271 1.1 we don't need to enable this bit. Cc: Stephen Chen Signed-off-by: Luis R.
