2019-02-11ath10k: enable Factory Test Mode for WCN3990Rakesh Pillai
The support to put WCN3990 firmware into Factory test mode is not present currently. The WCN3990 firmware can operate in Factory test mode based on the mode it receives in the wlan enable message from the host driver. When the host driver is started in testmode send the operating mode as UTF mode, to the WCN3990 firmware, in the wlan enable message to start the firmware in Factory test mode.

2019-02-07ath10k: fix hw-restart crash inject mode for WCN3990Rakesh Pillai
The hw-restart crash inject mode is a special mode, where there is no crash generated in the firmware, but instead the driver restarts the firmware. In order to restart WCN3990 firmware, the driver needs to send qmi_wlan_disable message followed by the qmi_wlan_enable message to the WCN3990 firmware. Currently the qmi_wlan_disable message is not sent to the WCN3990 firmware when hw-restart crash is injected, which causes the firmware to crash when the driver sends qmi_wlan_enable message during ath10k_restart. Send qmi_wlan_disable to the WCN3990 firmware when the hw-restart crash is injected via debugfs.

2019-02-04ath10k: Set DMA address mask to 35 bit for WCN3990Rakesh Pillai
WCN3990 is a 37-bit target but can address memory range only upto 35 bits. The 36th bit is used to control the smmu/iommu translation and the 37th bit is used by the internal bus masters to access the wifi subsystem internal SRAM. With the DMA mask set to 37i-bit, the host driver can get 37-bit dma address, which leads to incorrect address access in the target. Hence the host driver can used addresses upto 35-bit for WCN3990. Fix the dma mask for wcn3990 to 35-bit, instead of 37-bit.

2018-11-06ath10k: snoc: fix unbalanced clock error handlingBrian Norris
Similar to regulator error handling, we should only start tearing down the 'i - 1' clock when clock 'i' fails to enable. Otherwise, we might end up with an unbalanced clock, where we never successfully enabled the clock, but we try to disable it anyway.

2018-11-06ath10k: snoc: relax voltage requirementsBrian Norris
I rarely see drivers specify precise voltage requirements like this, but if we really have to...let's at least give a little wiggle room. Board designs (and accompanying device trees) may not provide exactly the voltage listed here, and we shouldn't fail to probe just because of this. Round these ranges down to the nearest volt, and provide a 0.05V margin. The regulator should provide its own supported ranges, which will helpfully intersect with these ranges. I would just as well remove these ranges entirely, but if I understand correctly, there's some reason that QCOM SoC's like to set zero / non-zero voltages.

2018-11-06ath10k: snoc: fix unabalanced regulator error handlingBrian Norris
If a regulator fails to set its voltage, we end up with an unbalanced call to regulator_disable(), because the error path starts with the current regulator (which was never enabled). Factor out the "on" function to perform (and unwind if failed) a single regulator at a time, and then main loop (ath10k_snoc_vreg_on()) can just worry about unwinding the regulators that were already enabled. It also helps to factor out the "off" function, to avoid repeating some code here.

2018-11-05ath10k: add support for WCN3990 firmware crash recoverySurabhi Vishnoi
Whenever the WCN3990 firmware becomes unavailable, the host driver receives a FW down indication, post which all the direct hardware register access should be avoided, in order to prevent improper behavior in the host driver. Set the crash_flush flag when the host driver receives a FW_DOWN_IND via qmi, in order to stop the untimely hardware register access. Also handle the case, where we need to do core register only for the first FW_READY indication, which is when we initialize the host driver. All the subsequent FW_READY indication will be received in subsystem recovery case and we only need to do the restart work. The state of driver is maintained using flags to distinguish between first and subsequent FW_READY indication received.

SRRI/DRRI are not mapped in the HW Shadow block and can lead to un-clocked access if common subsystem in the target is powered down due to idle mode. To mitigate this problem SRRI/DRRI can be read from DDR instead of doing an actual hardware read. Host allocates non cached memory on ddr and configures the physical address of this memory to the CE hardware. The hardware updates the RRI on this particular location.
