From 94f6345712b37e4bb23cb265ce4c65b9d177e75a Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Thu, 12 Dec 2019 08:57:58 -0800 Subject: bus: ti-sysc: Implement quirk handling for CLKDM_NOAUTO For dra7 dcan and dwc3 instances we need to block clockdomain autoidle. Let's do this with CLKDM_NOAUTO quirk flag and enable it for dcan and dwc3.
