Leon Yen 84feb629fc wifi: mt76: mt7925: introduce thermal protection 
[ Upstream commit 1d81e893b422a6f0ae70f8648867c2e73edfb413 ]

Add thermal protection to prevent the chip from possible overheating
due to prolonged high traffic and adverse operating conditions.

Henk Vergonet e7a1865056 wifi: mt76: mt76x2: Add support for LiteOn WN4516R,WN4519R 
[ Upstream commit 3c0e4f606d8693795a2c965d6f4987b1bfc31097 ]

Adds support for:
 - LiteOn WN4516R
 - LiteOn WN4519R
 Both use:
 - A nonstandard USB connector
 - Mediatek chipset MT7600U
 - ASIC revision: 76320044

Disabled VHT support on ASIC revision 76320044:

 This fixes the 5G connectibity issue on LiteOn WN4519R module
 see https://github.com/openwrt/mt76/issues/971

 And may also fix the 5G issues on the XBox One Wireless Adapter
 see https://github.com/openwrt/mt76/issues/200

 I have looked at the FCC info related to the MT7632U chip as mentioned in here:
 https://github.com/openwrt/mt76/issues/459
 These confirm the chipset does not support 'ac' mode and hence VHT should be turned of.

Shayne Chen 7e48358639 wifi: mt76: mt7996: fix RX buffer size of MCU event 
[ Upstream commit 42cb27af34de4acf680606fad2c1f2932110591f ]

Some management frames are first processed by the firmware and then
passed to the driver through the MCU event rings. In CONNAC3, event rings
do not support scatter-gather and have a size limitation of 2048 bytes.
If a packet sized between 1728 and 2048 bytes arrives from an event ring,
the ring will hang because the driver attempts to use scatter-gather to
process it.

To fix this, include the size of struct skb_shared_info in the MCU RX
buffer size to prevent scatter-gather from being used for event skb in
mt76_dma_rx_fill_buf().

Quan Zhou ac3af695c4 wifi: mt76: mt7925: fix fails to enter low power mode in suspend state 
[ Upstream commit 2d5630b0c9466ac6549495828aa7dce7424a272a ]

The mt7925 sometimes fails to enter low power mode during suspend.
This is caused by the chip firmware sending an additional ACK event
to the host after processing the suspend command. Due to timing issues,
this event may not reach the host, causing the chip to get stuck.
To resolve this, the ACK flag in the suspend command is removed,
as it is not needed in the MT7925 architecture. This prevents the
firmware from sending the additional ACK event, ensuring the device
can reliably enter low power mode during suspend.

Tested with mt7921e but the same pattern can be actually applied to other
mt76 drivers calling mt76_dma_cleanup() during removal. Tx napi is enabled
in their *_dma_init() functions and only toggled off and on again inside
their suspend/resume/reset paths. So it should be okay to disable tx
napi in such a generic way.

commit adc3fd2a2277b7cc0b61692463771bf9bd298036 upstream.

Address a kernel panic caused by a null pointer dereference in the
`mt792x_rx_get_wcid` function. The issue arises because the `deflink` structure
is not properly initialized with the `sta` context. This patch ensures that the
`deflink` structure is correctly linked to the `sta` context, preventing the
null pointer dereference.

commit b4ea6fdfc08375aae59c7e7059653b9877171fe4 upstream.

The code for handling ACPI configuration in CLC was copied from the mt7921
driver but is not utilized in the mt7925 implementation. So removes the
unused functionality to clean up the codebase.

Shayne Chen a64cf55327 wifi: mt76: mt7915: add module param to select 5 GHz or 6 GHz on MT7916 
commit 57af267d2b8f5d88485c6372761386d79c5e6a1a upstream.

Due to a limitation in available memory, the MT7916 firmware can only
handle either 5 GHz or 6 GHz at a time. It does not support runtime
switching without a full restart.

On older firmware, this accidentally worked to some degree due to missing
checks, but couldn't be supported properly, because it left the 6 GHz
channels uncalibrated.
Newer firmware refuses to start on either band if the passed EEPROM
data indicates support for both.

Deal with this limitation by using a module parameter to specify the
preferred band in case both are supported.
