From f1d63a59635feef3481ed1972a883a5d6be7f9bb Mon Sep 17 00:00:00 2001 From: Eyal Shapira Date: Tue, 31 Jan 2012 11:57:21 +0200 Subject: [PATCH] wl12xx: add support for HW dynamic PS FW now supports dynamic PS so we don't need to use mac80211 support. FW will go to PSM after a specified timeout with no Rx/Tx traffic. - Changed FW API to include new PS mode (AUTO_MODE) and including timeout parameter - The default PS mode would be dynamic PS - Default timeout is 100ms (same as it used to be in mac80211) - Avoid using mac80211 APIs to disable/enable dynamic PS as we're not using mac80211 PS control anymore. - COEX is handled by the FW while in dynamic PS so removed handling of SOFT_GEMINI Signed-off-by: Eyal Shapira Signed-off-by: Eliad Peller Signed-off-by: Luciano Coelho --- drivers/net/wireless/wl12xx/cmd.c | 3 ++- drivers/net/wireless/wl12xx/cmd.h | 5 +++-- drivers/net/wireless/wl12xx/conf.h | 6 ++++++ drivers/net/wireless/wl12xx/event.c | 8 -------- drivers/net/wireless/wl12xx/main.c | 15 +++++---------- drivers/net/wireless/wl12xx/ps.c | 15 ++++++++++----- 6 files changed, 26 insertions(+), 26 deletions(-) diff --git a/drivers/net/wireless/wl12xx/cmd.c b/drivers/net/wireless/wl12xx/cmd.c index 88e94c5938a4..bf3c37bd1f12 100644 --- a/drivers/net/wireless/wl12xx/cmd.c +++ b/drivers/net/wireless/wl12xx/cmd.c @@ -996,7 +996,7 @@ out: } int wl1271_cmd_ps_mode(struct wl1271 *wl, struct wl12xx_vif *wlvif, - u8 ps_mode) + u8 ps_mode, u16 auto_ps_timeout) { struct wl1271_cmd_ps_params *ps_params = NULL;
