From aa538aca9fb4a197464f5926c7b5d7050e9144b1 Mon Sep 17 00:00:00 2001 From: Rajkumar Manoharan Date: Wed, 16 Dec 2015 16:52:19 +0200 Subject: [PATCH] ath10k: wake up device before accessing registers commit 1aaf8efba0ae ("ath10k: disable PCI PS for QCA988X and QCA99X0") partially reverts pci soc powersave support added by commit 77258d409ce4 ("ath10k: enable pci soc powersaving"). While reverting the change, pci wake up function is called after accessing pci registers instead of prior to access. The assumption is that chip is woken up before accessing its registers.Though this change does not fix any known issues, this might help to avoid unknown or low power platform specific issues.
