2017-04-13rtlwifi: btcoex: 23b 2ant: let bt transmit when hw initialisation doneYan-Hsuan Chuang1-14/+31
During hw initialisation, wifi may be ready after bt has already been ready, which causes bt to act abnormally. To avoid this, set GNT_BT to high during hw init.

If bt is queing, we need to set the packet priority properly. Originally we only consider if wifi was connected or not, but now we also consider if bt is under abnormal scan or wifi is scanning, roaming or linking, and set the coex table.

2017-04-13rtlwifi: btcoex: 23b 2ant: add pnp notidy to avoid LPS/IPS mismatchYan-Hsuan Chuang1-0/+27
When driver is going to sleep, it does not leave LPS/IPS, thus the BTCoex may have mismatch when driver wakes up. To avoid that, BTCoex needs to clear the IPS/LPS state when it receives a pnp notify, then it can properly set up the hw when driver wakes up.

2017-04-13rtlwifi: btcoex: 23b 2ant: check PS state before setting tdma durationYan-Hsuan Chuang2-0/+101
For time division multiple access, the wifi and bt take turns to transmit, but we need to let AP know that wifi is under standby mode by sending null data to "pretend" entering power saving state using lps rpwm. But, the fw does not know if it is the actual power saving mode or just a fake one to cheat to the AP. Hence, before fw setting the tdma duration, the fw needs the driver to check the power saving state first.

2016-06-29rtlwifi: use s8 instead of charArnd Bergmann2-3/+3
Compiling the rtlwifi drivers for ARM with gcc -Wextra warns about lots of incorrect code that results from 'char' being unsigned here, e.g. realtek/rtlwifi/rc.c:113:18: error: comparison is always true due to limited range of data type [-Werror=type-limits] realtek/rtlwifi/rtl8188ee/dm.c:1070:22: error: comparison is always false due to limited range of data type [-Werror=type-limits] realtek/rtlwifi/rtl8192ce/trx.c:54:16: error: comparison is always false due to limited range of data type [-Werror=type-limits] realtek/rtlwifi/rtl8192cu/mac.c:601:16: error: comparison is always false due to limited range of data type [-Werror=type-limits] realtek/rtlwifi/rtl8192de/trx.c:53:16: error: comparison is always false due to limited range of data type [-Werror=type-limits] realtek/rtlwifi/rtl8192ee/phy.c:1268:12: error: comparison is always true due to limited range of data type [-Werror=type-limits] realtek/rtlwifi/rtl8192se/rf.c:150:20: error: comparison is always false due to limited range of data type [-Werror=type-limits] realtek/rtlwifi/rtl8723be/dm.c:877:29: error: comparison is always false due to limited range of data type [-Werror=type-limits] realtek/rtlwifi/rtl8723be/phy.c:386:16: error: comparison is always true due to limited range of data type [-Werror=type-limits] realtek/rtlwifi/rtl8821ae/dm.c:1514:38: error: comparison is always false due to limited range of data type [-Werror=type-limits] realtek/rtlwifi/rtl8821ae/phy.c:1558:11: error: comparison is always false due to limited range of data type [-Werror=type-limits] realtek/rtlwifi/rtl8821ae/phy.c:386:24: error: comparison is always false due to limited range of data type [-Werror=type-limits] realtek/rtlwifi/rtl8821ae/trx.c:55:12: error: comparison is always false due to limited range of data type [-Werror=type-limits] realtek/rtlwifi/stats.c:31:16: error: comparison is always false due to limited range of data type [-Werror=type-limits] This patch changes all uses of 'char' in this driver that refer to 8-bit integers to use 's8' instead, which is signed on all architectures.

The previous patch added an option to rtl8723be to manually select the antenna for those cases when only a single antenna is present, and the on-board EEPROM is incorrectly programmed. This patch implements the necessary changes in the Bluetooth coexistence driver.

2015-10-14rtlwifi: rtl818x: Move drivers into new realtek directoryLarry Finger16-0/+20424
Now that a new mac80211-based driver for Realtek devices has been submitted, it is time to reorganize the directories. Rather than having directories rtlwifi and rtl818x be in drivers/net/wireless/, they will now be in drivers/net/wireless/realtek/. This change simplifies the directory structure, but does not result in any configuration changes that are visable to the user.
