* | icnss: Use fixed memory region for WLAN MSA0 memoryHardik Kantilal Patel2017-07-07
|/ | | | | | | | | | | | | | During first time boot up WLAN Platform driver allocate 1 MB MSA0 Memory region. This region may be adjacent to other regions that also requires access control, due to that TZ will merge the two sections into one single resource group. During this Q6 will lose access to memory region causing a NOC Error. To avoid use fixed memory region for WLAN MSA0 memory.

* icnss: set vdd-0.8-cx-mx regulator optional for icnss driverSarada Prasanna Garnayak2017-03-06
| | | | | | | | | | | | | | | | | | | | The wlan firmware is configuring the clk and voltage regulator for hardware power on and hardware reset sequence. The icnss platform driver is configuring this clk and regulators to avoid invalid access to copy engine register during the wlan recovery. As platform driver is not configuring this regulator to power on or reset the WLAN hardware, So no need to define the voltage regulators are the required properties for the ICNSS platform driver. Define vdd-0.8-cx-mx as an optional voltage regulator for the icnss platform driver.

* icnss: Vote for hardware resourcesPrashanth Bhatta2017-02-24
| | | | | | | | | | | | | | | During recovery, there are cases where in WLAN driver running on APPS can access CE register causing exceptions because of hardware in reset state. Fix the issue by not resetting the hardware in WLAN firmware during recovery but halt the CE and MAC and reset the hardware only when reinitialization starts. For this to work, platform driver needs to keep the clock and regulator votes so that WLAN hardware will not go into weird state because of not resetting it but cutting the resources.

* icnss: Avoid DOMAIN_ATTR_ATOMIC setting during S1 bypassHardik Kantilal Patel2017-02-09
| | | | | | | | | | | While initializing the SMMU with DOMAIN_ATTR_ATOMIC attribute iommu driver always vote for aggre2_noc_clk during suspend mode which result into power penalty. To resolve this issue avoid configuring DOMAIN_ATTR_ATOMIC attribute in S1_BYPASS mode.

* icnss: Add support of monitoring vph_pwrYuanyuan Liu2016-09-12
| | | | | | | | | | | | Add support of monitoring runtime phone power. Driver configures two threshold values and receives notifications when phone power crosses either high or low threshold. Driver then sends indication to WLAN FW, which will vote for different regulator power mode based on the indication.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | vdd-wlan-xtal-aon-supply(LD0-4) need to be voted by cnss platform driver to keep wlan XO(LDO-5) ON during APPS suspend on mdmcalifornium platforms when wlan is turned ON as per Power UP sequence. Currently LDO-4 is only voted by USB driver when USB is connected. On removing USB, LDO-4 is turned off resulting LDO-5 turned off. When WLAN is turned on removing LDO-5 vote resulted in beaconing failures on mdmcalifornium platforms. Hence add a dummy vote to LDO-4 when WLAN is turned ON.
