From ff3cfe084885662843a6cc95a547eb9f8ef48fa5 Mon Sep 17 00:00:00 2001 From: Martin Schiller Date: Wed, 5 Dec 2018 08:51:13 +0100 Subject: [PATCH] ltq-atm/ltq-ptm: re-enable/fix reset_ppe() functionality for VR9 This patch re-enables the reset_ppe() functionality for VR9 targets by using the new lantiq rcu subsystem. The reset sequence in the reset_ppe() function was taken from the ppa datapath driver of lantiq UGW 7.4.1. Additionally it adds the required reset definitions to the vr9 dtsi file. It also prepares the reset_ppe() function calls for the other lantiq targets. This feature is needed to be able to switch between ltq-atm/ltq-ptm driver in ATM/PTM Auto-Mode at runtime.
