| |
The Wi-Fi module of Pine64 is powered via DLDO4 and ELDO1 (the latter one provides I/O voltage).
Add device node for it.
Although the Wi-Fi module is an external module which should be inserted to a header, according to my personal talk with TL Lim, he does not want this header to be used as GPIO (so it's with 2.0mm pitch, not 2.54mm as other GPIO headers).
Signed-off-by: Icenowy Zheng <icenowy@aosc.io> --- Changes in v3: - Added explaination on 2.0mm pitch.
