Subject: base-files: add helper functions for adding wlan device entries to board.json
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=7f9d3a00d8d41f2bf9fe35b30cd689b9992e7ff9;p=openwrt%2Fstaging%2Fjow.git

base-files: add helper functions for adding wlan device entries to board.json

These will be used to give WLAN PHYs a specific name based on path specified
in board.json. The platform board.d script can assign a specific order based
on available slots (PCIe slots, WMAC device) and device tree configuration.

This helps with maintaining config compatibility in case the device path
changes due to kernel upgrades.
