-Subject: [PATCH 2/2] arm64: dts: armada-3720-espressobin: set max link to gen1
-
-Since the beginning there's been an issue with initializing the Atheros
-based MiniPCIe wireless cards. Here's an example of kerenel log:
-
- OF: PCI: host bridge /soc/pcie@d0070000 ranges:
- OF: PCI: MEM 0xe8000000..0xe8ffffff -> 0xe8000000
- OF: PCI: IO 0xe9000000..0xe900ffff -> 0xe9000000
- advk-pcie d0070000.pcie: link up
- advk-pcie d0070000.pcie: PCI host bridge to bus 0000:00
- pci_bus 0000:00: root bus resource [bus 00-ff]
- pci_bus 0000:00: root bus resource [mem0xe8000000-0xe8ffffff]
- pci_bus 0000:00: root bus resource [io 0x0000-0xffff](bus address [0xe9000000-0xe900ffff])
- pci 0000:00:00.0: BAR 0: assigned [mem0xe8000000-0xe801ffff 64bit]
- pci 0000:00:00.0: BAR 6: assigned [mem0xe8020000-0xe802ffff pref]
- [...]

- ath9k: probe of 0000:00:00.0 failed with error -22
-
-The same happens for ath5k cards, while ath10k card didn't appear at
-all (not detected):
-
- OF: PCI: host bridge /soc/pcie@d0070000 ranges:
- OF: PCI: MEM 0xe8000000..0xe8ffffff -> 0xe8000000
- OF: PCI: IO 0xe9000000..0xe900ffff -> 0xe9000000
- advk-pcie d0070000.pcie: link never came up
- advk-pcie d0070000.pcie: PCI host bridge to bus 0000:00
- pci_bus 0000:00: root bus resource [bus 00-ff]
- pci_bus 0000:00: root bus resource [mem0xe8000000-0xe8ffffff]
- pci_bus 0000:00: root bus resource [io 0x0000-0xffff](bus address [0xe9000000-0xe900ffff])
- advk-pcie d0070000.pcie: config read/write timed out
-
-Following the issue on esppressobin.net forum [1] the workaround seems
-to be limiting the speed of PCIe bridge to 1st generation. This fixed
-the initialisation of all tested Atheros wireless cards.
-The patch in the forum thread swaped registers which would limit speed
-for all Armada 3700 based boards. The approach in this patch, in
-conjunction with "PCI: aardvark: allow to specify link capability" patch
-is less invasive, it only touches the affected board.
-
-For the record, the iwlwifi and mt76 cards were not affected by this
-issue.
