From 2435cdd0c3bb8ad067efb1b2f4c992f680c50b7c Mon Sep 17 00:00:00 2001 From: Gregory CLEMENT Date: Wed, 28 Feb 2018 17:35:30 +0100 Subject: PCI: armada8k: Fix clock resource by adding a register clock On Armada 7K/8K we need to explicitly enable the register clock. This clock is optional because not all the SoCs using this IP need it but at least for Armada 7K/8K it is actually mandatory. The binding documentation is updated accordingly.
