[PATCH v4 10/10] arm64: allwinner: a64: enable Wi-Fi for Pine64

Show all headers | View raw

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).
