Subject: ipq40xx: add PoE passthrough GPIO
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=b40cc46cc882ff97f2752e7837173ffc9f884eb9;p=openwrt%2Fstaging%2Fblocktrron.git

ipq40xx: add PoE passthrough GPIO

Add the GPIO pin of the PoE passthrough switch on the Aruba AP-303H.
Power is activated when the pin is low. It enables a PSE chip, so power
is only supplied to downstream devices when they are 802.3af/at
compliant devices.

Ensure you use a sufficient power supply when chaining a consuming
device after the AP.
