WiFi part of the module is called bcm43356 and can be used with the brcmfmac driver. The module is powered by the two always on regulators (not AXP805). WiFi uses a PG port with 1.8V voltage level signals. SoC needs to be configured so that it sets up an 1.8V input bias on this port. This is done by the pio driver by reading the vcc-pg-supply voltage. You'll need a fw_bcm43456c5_ag.bin firmware file and nvram.txt configuration that can be found in the Xulongs's repository for H6: https://github.com/orangepi-xunlong/OrangePiH6_external/tree/master/ap6256 Mainline brcmfmac driver expects the firmware and nvram at the following paths relative to the firmware directory: brcm/brcmfmac43456-sdio.bin brcm/brcmfmac43456-sdio.txt Signed-off-by: Ondrej Jirman --- Since RTC patches for H6 were merged, this can now go in too, if it looks ok. Other patches for this WiFi chip support were merged in previous cycles, so this just needs enabling in DTS now. Sorry for the links in the commit log, but this information is useful, even if the link itself goes bad. Any pointer what to google for (file names, tree name) is great for anyone searching in the future. Please take a look.
