From 79797b6fadf4d2b6ea639406e08c8ce1f259f6ae Mon Sep 17 00:00:00 2001 From: Martin Blumenstingl Date: Sun, 20 Aug 2017 00:18:17 +0200 Subject: reset: Add a reset controller driver for the Lantiq XWAY based SoCs The reset controllers (on xRX200 and newer SoCs have two of them) are provided by the RCU module. This was initially implemented as a simple reset controller. However, the RCU module provides more functionality (ethernet GPHYs, USB PHY, etc.), which makes it a MFD device. The old reset controller driver implementation from arch/mips/lantiq/xway/reset.c did not honor this fact. For some devices the request and the status bits are different.
