From 10107707196d67731de57126b846169c5b29aac0 Mon Sep 17 00:00:00 2001 From: Madhukar Pappireddy Date: Mon, 12 Aug 2019 18:31:33 -0500 Subject: Adding new optional PSCI hook pwr_domain_on_finish_late This PSCI hook is similar to pwr_domain_on_finish but is guaranteed to be invoked with the respective core and cluster are participating in coherency. This will be necessary to safely invoke the new GICv3 API which modifies shared GIC data structures concurrently.
