Subject: ipq806x: Add buttons to OnHub
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=4c1d7787d460cd0798eb01a42c6a8a7fc96e2999;p=openwrt%2Fstaging%2Fthess.git

ipq806x: Add buttons to OnHub

These are the factory reset button (external) and "developer mode"
button (hidden inside the case (ASUS) or under a screw in the base
(TP-Link)) found on the TP-Link and ASUS OnHub devices.

[Brian: add description; factor out for both ASUS and TP-Link; use
existing pinmux definitions; add keycode for dev button]
