timer - support - -This is a simple driver for the global timer module found in the Cortex -A9-MP cores from revision r1p0 onwards. This should be able to perform -the functions of the system timer and the local timer in an SMP system. - -The global timer has the following features: - The global timer is a 64-bit incrementing counter with an -auto-incrementing feature. It continues incrementing after sending -interrupts. The global timer is memory mapped in the private memory -region. - The global timer is accessible to all Cortex-A9 processors in the -cluster. Each Cortex-A9 processor has a private 64-bit comparator that -is used to assert a private interrupt when the global timer has reached -the comparator value. All the Cortex-A9 processors in a design use the -banked ID, ID27, for this interrupt. ID27 is sent to the Interrupt -Controller as a Private Peripheral Interrupt. The global timer is -clocked by PERIPHCLK. - -Signed-off-by: Stuart Menefy -Signed-off-by: Srinivas Kandagatla -CC: Arnd Bergmann -CC: Rob Herring -CC: Linus Walleij -CC: Will Deacon -CC: Thomas Gleixner -Signed-off-by: Daniel Lezcano ---- - .../devicetree/bindings/arm/global_timer.txt | 24 ++ - drivers/clocksource/Kconfig | 13 + - drivers/clocksource/Makefile | 1 + - drivers/clocksource/arm_global_timer.c | 321 ++++++++++++++++++++ - 4 files changed, 359 insertions(+) - create mode 100644 Documentation/devicetree/bindings/arm/global_timer.txt - create mode 100644 drivers/clocksource/arm_global_timer.c - ---- /dev/null -+++ b/Documentation/devicetree/bindings/arm/global_timer.txt -@@ -0,0 +1,24 @@ -+ -+* ARM Global Timer -+ Cortex-A9 are often associated with a per-core Global timer. -+ -+** Timer node required properties: -+ -+- compatible : Should be "arm,cortex-a9-global-timer" -+ Driver supports versions r2p0 and above. -+ -+- interrupts : One interrupt to each core -+ -+- reg : Specify the base address and the size of the GT timer -+ register window. -+ -+- clocks : Should be phandle to a clock. -+ -+Example: -+ -+ timer@2c000600 { -+ compatible = "arm,cortex-a9-global-timer"; -+ reg = <0x2c000600 0x20>; -+ interrupts = <1 13 0xf01>; -+ clocks = <&arm_periph_clk>; -+ }; ---- a/drivers/clocksource/Kconfig -+++ b/drivers/clocksource/Kconfig -@@ -67,6 +67,19 @@ config ARM_ARCH_TIMER - bool - select CLKSRC_OF if OF - -+config ARM_GLOBAL_TIMER -+ bool -+ select CLKSRC_OF if OF -+ help -+ This options enables support for the ARM global timer unit -+ -+config CLKSRC_ARM_GLOBAL_TIMER_SCHED_CLOCK -+ bool -+ depends on ARM_GLOBAL_TIMER -+ default y -+ help -+ Use ARM global timer clock source as sched_clock -+ - config CLKSRC_METAG_GENERIC - def_bool y if METAG - help ---- a/drivers/clocksource/Makefile -+++ b/drivers/clocksource/Makefile -@@ -28,4 +28,5 @@ obj-$(CONFIG_CLKSRC_EXYNOS_MCT) += exyno - obj-$(CONFIG_CLKSRC_SAMSUNG_PWM) += samsung_pwm_timer.o - - obj-$(CONFIG_ARM_ARCH_TIMER) += arm_arch_timer.o -+obj-$(CONFIG_ARM_GLOBAL_TIMER) += arm_global_timer.o - obj-$(CONFIG_CLKSRC_METAG_GENERIC) += metag_generic.o ---- /dev/null -+++ b/drivers/clocksource/arm_global_timer.c -@@ -0,0 +1,321 @@ -+/* -+ * drivers/clocksource/arm_global_timer.c -+ * -+ * Copyright (C) 2013 STMicroelectronics (R&D) Limited. -+ * Author: Stuart Menefy -+ * Author: Srinivas Kandagatla -+ * -+ * This program is free software; you can redistribute it and/or modify -+ * it under the terms of the GNU General Public License version 2 as -+ * published by the Free Software Foundation. -+ */ -+ -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+#include -+ -+#include -+ -+#define GT_COUNTER0 0x00 -+#define GT_COUNTER1 0x04 -+ -+#define GT_CONTROL 0x08 -+#define GT_CONTROL_TIMER_ENABLE BIT(0) /* this bit is NOT banked */ -+#define GT_CONTROL_COMP_ENABLE BIT(1) /* banked */ -+#define GT_CONTROL_IRQ_ENABLE BIT(2) /* banked */ -+#define GT_CONTROL_AUTO_INC BIT(3) /* banked */ -+ -+#define GT_INT_STATUS 0x0c -+#define GT_INT_STATUS_EVENT_FLAG BIT(0) -+ -+#define GT_COMP0 0x10 -+#define GT_COMP1 0x14 -+#define GT_AUTO_INC 0x18 -+ -+/* -+ * We are expecting to be clocked by the ARM peripheral clock. -+ * -+ * Note: it is assumed we are using a prescaler value of zero, so this is -+ * the units for all operations. -+ */ -+static void __iomem *gt_base; -+static unsigned long gt_clk_rate; -+static int gt_ppi; -+static struct clock_event_device __percpu *gt_evt; -+ -+/* -+ * To get the value from the Global Timer Counter register proceed as follows: -+ * 1.
