From: Martin Schiller Date: Wed, 5 Dec 2018 07:51:13 +0000 (+0100) Subject: ltq-atm/ltq-ptm: re-enable/fix reset_ppe() functionality for VR9 X-Git-Tag: v19.07.0-rc1~1086 X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=ff3cfe084885662843a6cc95a547eb9f8ef48fa5;p=openwrt%2Fopenwrt.git 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.
