From mboxrd@z Thu Jan 1 00:00:00 1970 From: Stephen Boyd Subject: [PATCH 0/4] Memory mapped architected timers Date: Mon, 8 Apr 2013 19:30:19 -0700 Message-ID: <1365474623-29181-1-git-send-email-sboyd@codeaurora.org> Return-path: Sender: linux-kernel-owner@vger.kernel.org To: linux-arm-kernel@lists.infradead.org Cc: linux-kernel@vger.kernel.org, linux-arm-msm@vger.kernel.org, Mark Rutland , Marc Zyngier , devicetree-discuss@lists.ozlabs.org List-Id: devicetree@vger.kernel.org This patchset adds support for memory mapped architected timers. We don't have any other global broadcast timer in our system, so we use the mmio timer during low power modes. The first patch is the binding. The next two patches lay some groundwork so that the last patch is simpler. The final patch adds support for mmio timers. Patches are based on a recent patch from Mark that removes the physical count reading (clocksource: arch_timer: use virtual counter, message id <1364404312-4427-4-git-send-email-mark.rutland@arm.com>).
