From mboxrd@z Thu Jan 1 00:00:00 1970 From: tony@atomide.com (Tony Lindgren) Date: Mon, 23 Apr 2018 10:45:46 -0700 Subject: [PATCH 13/16] bus: ti-sysc: Detect omap4 type timers for quirk In-Reply-To: <20180423174549.57412-1-tony@atomide.com> References: <20180423174549.57412-1-tony@atomide.com> Message-ID: <20180423174549.57412-14-tony@atomide.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org 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.
