The Intel 7260 wifi mini pcie card now just works fine (272mbps~ on a 5ghz AC wifi) with the latest kernel packaged by Arch Linux (which includes the required advk pci fixes).

My bad. Sorry for the noise.

It looks like mainline dtb lack some definition regarding cpu idle states, thermal sensors and cpu freq scaling is not supported. However, the marvell tree does seem to have some patches for it, are they going to be mainlined at some point ?

Here are a bunch of patches (non-exhaustive list) from the marvell tree (note that they do not apply cleanly on top of the 4.12 release nor master):
* https://github.com/MarvellEmbeddedProcessors/linux-marvell/commit/9bc883aaa5a90a46aed85108e2adb79380afbe47
* https://github.com/MarvellEmbeddedProcessors/linux-marvell/commit/965d69eae60668d0f5b3bfdcaeab81fcd94e152c

Done.

Finally got the intel 7260 card to initialize and work properly by enabling cfg80211 extensions compatibility in the kernel.

Who should I contact in order to get those patches submitted to the linux-arm mailing ?

Applying the following pci aardvark patches from the marvell tree [1] get rid of the kernel panics (however i cannot get the intel 7260 card to init properly [2]):

Hi,

I tested with an intel 7260 mini pcie card and it makes the kernel panic (tested with the kernel provided by Marvell and the kernel provided by Arch Linux).

[mm]

Ping.

Arch Linux now packages a kernel based on the 4.12.0 with the patches I mentionned above applied.
The sdcard slot and perf counters now work, however, I still have issues with the mini pcie slot when the intel 7260 wifi card is plugged.

[mm]

Here is the tarball which contains the configuration mentionned above: http://0x5c.me/linux-4.12.0.tgz
It contains the kernel image, the modules, the kernel configuration and the dtb. It is based on a bare 4.12.0 kernel without additional patches. The configuration is obtained via:
* make defconfig
* make menuconfig to enable the iwlwifi driver, dsa and the specific dsa driver needed by the board

I boot the kernel with the following uboot configuration:

fdt_addr=0x1000000
fdt_high=0xffffffffffffffff
kernel_addr=0x2000000

booti $kernel_addr – $fdt_addr

And here is the trace I get when I boot the board with the intel 7260 mini pcie wifi card: http://sprunge.us/haED

I also noticed that this patchset has been sent to the linux-arm mailing list a few days ago:
[5/5] ARM64: dts: marvell: armada37xx: Enable USB2 on espressobin
[4/5] ARM64: dts: marvell: armada37xx: Wire PMUv3
[3/5] ARM64: dts: marvell: armada37xx: Enable memory-mapped GIC CPU interface
[2/5] ARM64: dts: marvell: armada37xx: Fix GIC maintenance interrupt
[1/5] ARM64: dts: marvell: armada37xx: Fix timer interrupt specifiers

Is there an ongoing fix for the mini pcie (pcie-aardvark) interface ?
