* ath9k: add extra GPIO led supportMiaoqing Pan2015-04-07
| | | | | | | | | ar9550 or later chips, the AR_GPIO_IN_OUT register only can control GPIO[0:3]. For the extra GPIO, use standard GPIO calls instead of WMAC internal registers. Signed-off-by: Miaoqing Pan <miaoqing@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
* ath9k: add new function ath9k_hw_read_arrayOleksij Rempel2015-03-30
| | | | | | | | REG_READ generate most overhead on usb bus. It send and read micro packages and reduce usb bandwidth. To reduce this overhead we should read in batches. Signed-off-by: Oleksij Rempel <linux@rempel-privat.de> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
* ath9k_htc: add new WMI_REG_RMW_CMDID commandOleksij Rempel2015-03-30
| | | | | | | | | | | | Since usb bus add extra delay on each request, a command with read + write requests is too expensive. We can dramtically reduce usb load by moving this command to firmware. In my tests, this patch will reduce channel scan time for about 5-10 seconds. Signed-off-by: Oleksij Rempel <linux@rempel-privat.de> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

* ath9k: Fix issues with WoW enableSujith Manoharan2015-02-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch addresses several issues with the ath9k_hw_wow_enable() routine: * The usage of set/clr variables is removed. Writing the required values to registers is cleaner. * The shift value of 28 for the contention window field in AR_WOW_PATTERN is incorrect, change it to 27. * Disabling Keep Alive needs to be done based on the LINK_CHANGE option. This is done unconditionally now, fix this. * The workaround for the D1/D3 issue is required only for AR9462. * The bitfield for enabling pattern matching for packets less than 256 bytes has expanded for new chips, handle this accordingly. * General cleanup.

* ath9k: Add support for more WOW patternsSujith Manoharan2015-02-06

* ath9k: Enable TSF2 for generic HW timersSujith Manoharan2014-11-17
| | | | | | | | | | | | | | | The base TSF is used for HW timers 0..7, but chips in the AR9003 family and above can support more generic timers. To use them, however, a second HW TSF needs to be enabled. This patch allows usage of the extra timers by starting the second TSF properly. The extra set of HW timers is apparently also present in AR9287, but we enable it only for the AR9003 family.

* ath9k: Use a separate TX gain table for WZR-HP-G450HSujith Manoharan2013-12-09
| | | | | | | | | | | | | | | | | | | | The Buffalo device WZR-HP-G450H uses the index 3 for TX gain, which is set to the high_power table currently. Later variants of the router use the same index, but instead refer to the low_ob_db gain table. This is not handled in the driver since there is no way to distinguish board revisions and the high_power table is used (incorrectly) for the newer variants. By default, devices based on AR9300 using the TX gain index 3 have to use the high_power table. To make sure that WZR-HP-G450H is not broken when the high_power table is updated, use a separate array based on information obtained from the platform data. The current situation where only the original variant of WZR-HP-G450H works properly stays unchanged. Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: John W.
