Kalle Valo says:

====================
wireless-drivers-next patches for 5.1

Last set of patches. A new hardware support for mt76 otherwise quite
normal.

Major changes:

mt76

* add driver for MT7603E/MT7628

ath10k

* more preparation for SDIO support

wil6210

* support up to 20 stations in AP mode

device. The node is expected to be specified as a child node of the PCI

controller to which the wireless chip is connected.



Alternatively, it can specify the wireless part of the MT7628/MT7688 SoC.

For SoC, use the compatible string "mediatek,mt7628-wmac" and the following

properties:



- reg: Address and length of the register set for the device.

- interrupts: Main device interrupt
