+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 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")

+
+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.

+ 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.

+To do not brake HW restart we should keep initialization vectors data.

+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

+
+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.
