2012-07-18wlcore: wait for command completion event when sending CMD_ROLE_STOPLuciano Coelho
We need to wait for the command completion event when we send the CMD_ROLE_STOP event otherwise we may try to send CMD_ROLE_START too soon and get out-of-sync with the firmware. In some cases, the firmware may not send the event, so we wait for the event or for the timeout, whichever comes first. This patch is based on an earlier version by Eliad.

2012-07-18wlcore: make usage of nla_put clearerYair Shapira
handle errors of nla_put() inside the if(nla_put...) {} This makes the code simpler and clearer because: we take advantage from the fact that we have only one nla_put in our routines (so no real need for goto label). this avoids ugly goto forward followed by goto backward.

2012-07-18wlcore/wl12xx: calibrator fem detect implementationYair Shapira
this completes the calibrator based fem detect logic in driver: driver starts (by calibrator) in plt_mode PLT_FEM_DETECT wlcore inits and starts plt on wl12xx wl12xx fetches fem number from firmware and stores it in wl->fem_manuf wl12xx immediatly returns (doesn't start radio, etc...) wlcore returns the fem_manuf to calibrator using WL1271_TM_ATTR_DATA plt_mode is stopped Signed-off-by: Yair Shapira <yair.shapira@ti.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-07-18wl18xx: disable calibrator based fem detectYair Shapira
bip calibration is not required in wl18xx. Therefore we disable also auto fem (using calibrator fem detect) mode. Signed-off-by: Yair Shapira <yair.shapira@ti.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-07-18wlcore: add plt_mode including new PLT_FEM_DETECTYair Shapira
add wl->plt_mode that is used to indicate different plt working modes: this will be used to implement calibrator side auto fem detection where driver asks firmware to detect the wlan fem radio type and returns it to calibrator. this is not implemented yet and plt_modes: PLT_ON and PLT_FEM_DETECT currently behave the same.

2012-07-18wlcore: use basic rates for non-data packetsEliad Peller
After the latest mac80211 changes, the sta has the ap's sta pointer even before association. This cause the auth and assoc frames to be sent with the standard ap's rates, rather than the basic rates. Change the tx rate policy logic to use the regular ap rates only for data packets (so control and mgmt packets will be sent with basic rates) Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>

2012-07-18wl18xx: add support for ht_mode in conf.hYair Shapira
ht_mode added to wl18xx conf struct in order to support different modes from the configuration file, as well as module params, and by default (working without a conf file and/or no module params). the hack regarding conf.phy.low_band_component_type for each board is now explicitly handled after parsing module params. missing default values to wl18xx config added. fix string module params not to have defaults (so if empty, param can be taken from conf file). update conf version to 3.

2012-07-18Clk: SPEAr1340: Update sys clock parent arrayVipul Kumar Samar
sys_clk has multiple parents and selection of parent depends on sys_clk_ctrl register bit no. 23:25, with following possibilities 0XX: pll1_clk 10X: sys_synth_clk 110: pll2_clk 111: pll3_clk Out of several possibilities (h/w wise) to select same clock parent for sys_clk, current clock implementation was considering just one value. When bootloader programmed different (valid) value to select a clock parent then Linux breaks. Here, we try to include all possibilities which can lead to same clock selection thus making Linux independent of bootloader selection values.
