From 8cde5d5f7361fd152dd67df552596919d89ac404 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Mon, 16 Apr 2018 10:25:15 -0700 Subject: bus: ti-sysc: Detect omap4 type timers for quirk Starting with omap4 some timers have different sysc registers (type2) compared to the omap2 timers (type1). We need to detect these to enable the quirk for SYSC_QUIRK_LEGACY_IDLE, otherwise these won't be idling properly.
