Function _rtl92c_evm_db_to_percentage is functionally identical to the generic version rtl_evm_db_to_percentage, so remove _rtl92c_evm_db_to_percentage and use the generic version instead. Signed-off-by: Michael Straube <straube.linux@gmail.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

2019-09-13rtw88: add dynamic cck pd mechanismTzu-En Huang
This mechanism reduces the numbers of false alram in cck rate by dynamically adjusting the value of power threshold and cs_ratio. We determine the new value by three factors, which are rssi, false alarm count and igi. Based on these factors, we define the current condition into five levels. Compared to the previous level, if the level is changed, we set the new values for power threshold and cs_ratio.

2019-09-13rtw88: move IQK/DPK into phy_calibrationYan-Hsuan Chuang
Since 8822c requires to do not only IQK, but also DPK. Move these calibrations that need to be done once the channel is determined, into phy_calibration. And note that the order of the calibrations matters, 8822c should do IQK first, then DPK. Signed-off-by: Yan-Hsuan Chuang <yhchuang@realtek.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
2019-09-13rtw88: 8822c: add SW DPK supportTzu-En Huang
Power amplifiers are not linear components, and require DPK to reduce its nonlinearity. DPK is called Digital Pre-distortion Calibration, can be used to compensate the output of power. DPK tracking is in charge of tracking the thermal changes. And it then shifts the power curve accordingly, which makes the power output remains linear even if the PA works in different temperature. To perform DPK, the parameter table should also be updated. And the table will be applied when device is powered on. Then DPK will reference the values to calibrate.

2019-09-13rtw88: 8822c: add FW IQK supportYan-Hsuan Chuang
Add support for doing IQK in firmware Ideally the RF component's I/Q vectors should be orthogonal, but usually they are not. So we need to calibrate for the RF components, ex. PA/LNA, ADC/DAC. And if the I/Q vectors are more orthogonal, the mixed signal will have less deviation. This helps with those rates with higher modulation (MCS8-9), because they have more strict EVM/SNR requirement. Also the better of the quality of the signal, the longer it can propagate, and the better throughput performance we can get.

Port the same fix for ixgbe to ixgbevf. The ixgbevf driver currently does IPsec Tx offloading based on an existing secpath. However, the secpath can also come from the Rx side, in this case it is misinterpreted for Tx offload and the packets are dropped with a "bad sa_idx" error. Fix this by using the xfrm_offload() function to test for Tx offload.

Lukasz fixes how the firmware version is stored to align with how the firmware stores its own version. Also extended the log message to display additional useful information such as NVM version, API patch information and firmware build hash.

Jake updates i40e to use ktime_get_real_ts64() instead of ktime_to_timespec64(). Removes the define for bit 0x0001 for cloud filters, since it is a reserved bit and not a valid type.

2019-09-13mmc: tmio: Fixup runtime PM management during probeUlf Hansson
The tmio_mmc_host_probe() calls pm_runtime_set_active() to update the runtime PM status of the device, as to make it reflect the current status of the HW. This works fine for most cases, but unfortunate not for all. Especially, there is a generic problem when the device has a genpd attached and that genpd have the ->start|stop() callbacks assigned. More precisely, if the driver calls pm_runtime_set_active() during ->probe(), genpd does not get to invoke the ->start() callback for it, which means the HW isn't really fully powered on. Furthermore, in the next phase, when the device becomes runtime suspended, genpd will invoke the ->stop() callback for it, potentially leading to usage count imbalance problems, depending on what's implemented behind the callbacks of course. To fix this problem, convert to call pm_runtime_get_sync() from tmio_mmc_host_probe() rather than pm_runtime_set_active(). Additionally, to avoid bumping usage counters and unnecessary re-initializing the HW the first time the tmio driver's ->runtime_resume() callback is called, introduce a state flag to keeping track of this.

2019-09-13padata: remove cpu_index from the parallel_queueDaniel Jordan
With the removal of the ENODATA case from padata_get_next, the cpu_index field is no longer useful, so it can go away.

2019-09-13padata: unbind parallel jobs from specific CPUsDaniel Jordan
Padata binds the parallel part of a job to a single CPU and round-robins over all CPUs in the system for each successive job. Though the serial parts rely on per-CPU queues for correct ordering, they're not necessary for parallel work, and it improves performance to run the job locally on NUMA machines and let the scheduler pick the CPU within a node on a busy system. So, make the parallel workqueue unbound. Update the parallel workqueue's cpumask when the instance's parallel cpumask changes. Now that parallel jobs no longer run on max_active=1 workqueues, two or more parallel works that hash to the same CPU may run simultaneously, finish out of order, and so be serialized out of order. Prevent this by keeping the works sorted on the reorder list by sequence number and checking that in the reordering logic. padata_get_next becomes padata_find_next so it can be reused for the end of padata_reorder, where it's used to avoid uselessly queueing work when the next job by sequence number isn't finished yet but a later job that hashed to the same CPU has. The ENODATA case in padata_find_next no longer makes sense because parallel jobs aren't bound to specific CPUs. The EINPROGRESS case takes care of the scenario where a parallel job is potentially running on the same CPU as padata_find_next, and with only one error code left, just use NULL instead.

2019-09-13padata: use separate workqueues for parallel and serial workDaniel Jordan
padata currently uses one per-CPU workqueue per instance for all work. Prepare for running parallel jobs on an unbound workqueue by introducing dedicated workqueues for parallel and serial work.
