2019-02-20ath10k: switch to use SPDX license identifiersKalle Valo1-12/+1
Use SPDX identifiers everywhere in ath10k. Makefile was incorrectly marked in commit b24413180f56 ("License cleanup: add SPDX GPL-2.0 license identifier to files with no license"), fix that as well. Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2018-12-19ath10k: skip sending quiet mode cmd for WCN3990Rakesh Pillai1-0/+9
HL2.0 firmware does not support setting quiet mode. If the host driver sends the quiet mode setting command to the HL2.0 firmware, it crashes with the below signature. fatal error received: err_qdi.c:456:EX:wlan_process:1:WLAN RT:207a:PC=b001b4f0 The quiet mode command support is exposed by the firmware via thermal throttle wmi service. Enable ath10k thermal support if thermal throttle wmi service bit is set. 10.x firmware versions support this feature by default, but unfortunately do not advertise the support via service flags, hence have to manually set the service flag in ath10k_core_compat_services(). Tested on QCA988X with 10.2.4.70.9-2. Also tested on WCN3990.

2017-06-28ath10k: add const to thermal_cooling_device_ops structureBhumika Goyal1-1/+1

2016-09-02ath10k: replace config_enabled() with IS_REACHABLE()Masahiro Yamada1-1/+1
Commit 97f2645f358b ("tree-wide: replace config_enabled() with IS_ENABLED()") mostly did away with config_enabled(). This is one of the postponed TODO items as config_enabled() is used for a tristate option here. Theoretically, config_enabled() is equivalent to IS_BUILTIN(), but I guess IS_REACHABLE() is the best fit for this case because both CONFIG_HWMON and CONFIG_ATH10K are tristate.

2015-03-23ath10k: move driver state check before setting throttleRajkumar Manoharan1-9/+4
Since thermal daemon is unaware of the device state, it might try to adjust the throttle state when the device is powered down. So the driver caches the value and will configure it while powering up the target. The cached value will be programed later once the device is brought up. In such case, returning error status is confusing and misleading the user application. Hence moving the driver state check before sending wmi command to target.

2015-03-23ath10k: cache throttle state when device is downRajkumar Manoharan1-7/+7
Allow driver to cache the throttle state when the devie is not yet started. Configure the cached throttle state while powering up the device. Since thermal daemon is unaware of the up/down cycle, it assumes that device is throttled.

2015-03-23ath10k: fix interpretation of cooling device stateRajkumar Manoharan1-16/+19
Setting the sysfs attribute ends up configuring the duty cycle, but the interface through which the attribute is exposed (cooling_device) is for setting the throttle/cooling state. This is confusing the user. Hence renaming the cooling device interfaces for better readability.

2014-12-23ath10k: add thermal sensor device supportRajkumar Manoharan1-0/+83
Temperature sensor generates electrical analog voltage from temperature of each chain. The analog voltage is converted to digital value through ADC. For reading temperature values fom user space, hw monitoring device is used. Whenever the user requests for current temperature, the driver sends WMI command and wait for response.

2014-12-23ath10k: add thermal cooling device supportRajkumar Manoharan1-0/+155
Thermal cooling device support is added to control the temperature by throttling the data transmission for the given duration. Throttling is done using hw MAC quiet time setting. Period, duration and offset from TBTT can be set up to quiet the MAC transmits for the required duty cycle (% of quiet duration). The thermal device allows user to configure duty cycle. The quiet params are derived as follows. period = max(25TU, beacon interval / number of bss) duration = period * duty cycle / 100 Quiet mode can be disabled by setting the duty cycle to 0. The cooling device can be found under /sys/class/thermal/cooling_deviceX/. Corresponding soft link to this device can be found under phy folder. /sys/class/ieee80211/phy*/device/cooling_device.
