From dc122f4d9e44adfd73c27111b00210ad2c0c3555 Mon Sep 17 00:00:00 2001 From: Zoltan HERPAI Date: Sun, 17 Jan 2021 23:26:33 +0100 Subject: [PATCH] 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.
