| * cnss2: Add cold cal support to QCN7605 Ver 2.0 devicesRajasekaran Kalidoss2019-10-30
| | | | | | | | | | | | | | | | | | Added macro for QCN7605 2.0 USB devices to enable fs_ready. This enables cold boot calibration trigger for QCN7605 2.0 USB devices. Change-Id: Icbaa6867f87d9057050531c78a7aa868395330b3 Signed-off-by: Rajasekaran Kalidoss <rkalidos@codeaurora.org>
* | cnss2: Fix for WL_EN toggling failureJayachandran Sreekumaran2019-11-13
|/ | | | | | | | | | Regulator_enable API is getting called twice for wl_en. But for wlan driver unload, regulator_disable gets called only once. Hence SoC reset is not happening during the wlan driver unload. Removed the second regulator_enable call in wlan driver load path.

WLAN firmware can toggle this pin to wakeup the Host when wireless wakeup is triggered.

* cnss2: Support USB SSR and disconnect scenariosRajasekaran Kalidoss2019-04-09
| | | | | | | | | | | | | | For USB devices, irrecoverable scenarios in firmware can lead to USB bus disconnect. In USB disconnect, the interface and dev structures passed by USB sub system are freed and are no longer valid. The current implementation is PCIe specific and assumes dev struct being present and valid always. The clean way to handle this for HL(USB/SDIO) is to call pld_usb_remove in disconnect and pld_usb_probe in re-connect after a recovery Change-Id: I3fc9a5a2fc7bb53439b0410e61f381aa94e18634 Signed-off-by: Rajasekaran Kalidoss <rkalidos@codeaurora.org>

| * cnss2: Disable PCIe bus master bit before save config spaceNirav Shah2019-02-13
| | | | | | | | | | | | | | | | | | | | | | | | There may be a issue if save PCIe config space with bus master enabled. During resume, since the bit will be restored first, device will think master is ready and then trigger MSI for some events, but actually MSI config has not been restored yet which will mask the MSI. To avoid this, clear the bus master bit before save config space and the bit will be enabled at a later time.
