Subject: [PATCH 02/15] rt2800: add helpers for reading dma done index
For mmio we do not properlly trace dma done Q_INDEX_DMA_DONE index
for TX queues. That would require implementing INT_SOURCE_CSR_*_DMA_DONE
interrupts, what is rather not worth to do due to adding extra
CPU load (small but still somewhat not necessary otherwise).
We can just read TX DMA done indexes from registers directly. What
will be used by watchdog.

Subject: [PATCH 03/15] rt2800: initial watchdog implementation
Add watchdog for rt2800 devices. For now it only detect hung
and print error.
[Note: I verified that printing messages from process context is
fine on MT7620 (WT3020) platform that have problem when printk
is called from interrupt context].

Subject: [PATCH 05/15] rt2800: do not nullify initialization vector data
If we restart hw we should keep existing IV (initialization vector)
otherwise HW encryption will be broken after restart.
Also fix some coding style issues on the way.

Date: Mon, 1 Jul 2019 12:53:13 +0200
Subject: [PATCH 08/15] rt2x00usb: fix rx queue hang
Since commit ed194d136769 ("usb: core: remove local_irq_save() around
->complete() handler") the handler rt2x00usb_interrupt_rxdone() is
not running with interrupts disabled anymore. So this completion handler
is not guaranteed to run completely before workqueue processing starts
for the same queue entry.
Be sure to set all other flags in the entry correctly before marking
this entry ready for workqueue processing. This way we cannot miss error
conditions that need to be signalled from the completion handler to the
worker thread.
Note that rt2x00usb_work_rxdone() processes all available entries, not
only such for which queue_work() was called.
This patch is similar to what commit df71c9cfceea ("rt2x00: fix order
of entry flags modification") did for TX processing.
This fixes a regression on a RT5370 based wifi stick in AP mode, which
suddenly stopped data transmission after some period of heavy load. Also
stopping the hanging hostapd resulted in the error message "ieee80211
phy0: rt2x00queue_flush_queue: Warning - Queue 14 failed to flush".
Other operation modes are probably affected as well, this just was
the used testcase.
Fixes: ed194d136769 ("usb: core: remove local_irq_save() around ->complete() handler")

Subject: [PATCH 09/15] rt2x00usb: remove unnecessary rx flag checks
In contrast to the TX path, there is no need to separately read the transfer
status from the device after receiving RX data. Consequently, there is no
real STATUS_PENDING RX processing queue entry state.
Remove the unnecessary ENTRY_DATA_STATUS_PENDING flag checks from the RX path.
Also remove the misleading comment about reading RX status from device.

Subject: [PATCH 10/15] rt2x00: no need to check return value of debugfs_create
functions
When calling debugfs functions, there is no need to ever check the
return value. The function can work or not, but the code logic should
never do something different based on this.
Because we don't need to save the individual debugfs files and
directories, remove the local storage of them and just remove the entire
debugfs directory in a single call, making things a lot simpler.

Subject: [PATCH 12/15] rt2x00: clear IV's on start to fix AP mode regression
To do not brake HW restart we should keep initialization vectors data.
I assumed that on start the data is already initialized to zeros, but
that not true on some scenarios and we should clear it. So add
additional flag to check if we are under HW restart and clear IV's
data if we are not.
Patch fixes AP mode regression.

Subject: [PATCH 13/15] rt2x00: do not set IEEE80211_TX_STAT_AMPDU_NO_BACK on
tx status
According to documentation IEEE80211_TX_STAT_AMPDU_NO_BACK is suppose
to be used when we do not recive BA (BlockAck). However on rt2x00 we
use it when remote station fail to decode one or more subframes within
AMPDU (some bits are not set in BlockAck bitmap). Setting the flag result
in sent of BAR (BlockAck Request) frame and this might result of abuse
of BA session, since remote station can sent BA with incorrect
sequence numbers after receiving BAR. This problem is visible especially
when connecting two rt2800 devices.
Previously I observed some performance benefits when using the flag
when connecting with iwlwifi devices. But currently possibly due
to reacent changes in rt2x00 removing the flag has no effect on
those test cases.
So remove the IEEE80211_TX_STAT_AMPDU_NO_BACK.

This reverts commit 9ad3b55654455258a9463384edb40077439d879f.
As reported by Sergey:
"I got some problem after upgrade kernel to 5.2 version (debian testing
linux-image-5.2.0-2-amd64). 5Ghz client stopped to see AP.
Some tests with 1metre distance between client-AP: 2.4Ghz -22dBm, for
5Ghz - 53dBm !, for longer distance (8m + walls) 2.4 - 61dBm, 5Ghz not
visible."
It was identified that rx signal level degradation was caused by
9ad3b5565445 ("rt2800: enable TX_PIN_CFG_LNA_PE_ bits per band").
So revert this commit.

Hence remove errornous line 5281 to make the driver actually
execute the correct initialization routine for MT7620 chips.
As it was requested by Stanislaw Gruszka remove setting values of
MIMO_PS_CFG and TX_PIN_CFG. MIMO_PS_CFG is responsible for MIMO
power-safe mode (which is disabled), hence we can drop setting it.
TX_PIN_CFG is set correctly in other functions, and as setting this
value breaks some devices, rather don't set it here during init, but
only modify it later on.
