Subject: sunxi: add modules for AC100 MFD and RTC
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=dc122f4d9e44adfd73c27111b00210ad2c0c3555;p=openwrt%2Fopenwrt.git

sunxi: add modules for AC100 MFD and RTC

The X-Powers AC100 is a multi-function IC used to provide RTC
and audio codec via RSB (reduced serial bus, an Allwinner-
speciality). On some boards using the A80/A83T SoCs, aside
from the RTC functionality, the RTC is used as a clocksource
for the Ampak WiFi/BT modules.

Add modules for the core MFD support and the RTC.
