commit b2934279c3e9719145ff4090d4ab951e340df17e upstream. The current version has a new USB ID and reports as an 0x7632 device. Adding the IDs results in it working out of the box.

2020-03-18mt76: fix array overflow on receiving too many fragments for a packetFelix Fietkau1-3/+6
commit b102f0c522cf668c8382c56a4f771b37d011cda2 upstream. If the hardware receives an oversized packet with too many rx fragments, skb_shinfo(skb)->frags can overflow and corrupt memory of adjacent pages. This becomes especially visible if it corrupts the freelist pointer of a slab page.

2020-01-26mt76: mt76u: rely on usb_interface instead of usb_devLorenzo Bianconi4-6/+13
[ Upstream commit 80df01f4dc79abbed724bbe0851cab3fe8ad9d99 ] usb drivers are supposed to communicate using usb_interface instead mt76x{0,2}u is now registering through usb_device. Fix it by passing usb_intf device to mt76_alloc_device routine.

2019-10-30mt76: dma: fix buffer unmap with non-linear skbsLorenzo Bianconi2-4/+7
mt76 dma layer is supposed to unmap skb data buffers while keep txwi mapped on hw dma ring. At the moment mt76 wrongly unmap txwi or does not unmap data fragments in even positions for non-linear skbs. This issue may result in hw hangs with A-MSDU if the system relies on IOMMU or SWIOTLB. Fix this behaviour properly unmapping data fragments on non-linear skbs.

On same device (e.g. U7612E-H1) PCIE_ASPM causes continuous mcu hangs and instability. Since mt76x2 series does not manage PCIE PS states, first we try to disable ASPM using pci_disable_link_state. If it fails, we will disable PCIE PS configuring PCI registers.
