Signed-off-by: Stephen Warren --- v4: Adjust to changes in the rest of the patch series. v3: Rework using CLKSRC_OF_MATCH_TABLE() for registration, rather than a manually maintained table in clksrc-of.c. v2: Rebase on ARM sys_timer rework, and addition of clocksource_of_init(). --- arch/arm/Kconfig | 1 + arch/arm/mach-tegra/Makefile | 1 - arch/arm/mach-tegra/board-dt-tegra20.c | 3 ++- arch/arm/mach-tegra/board-dt-tegra30.c | 3 ++- arch/arm/mach-tegra/board.h | 1 - drivers/clocksource/Makefile | 1 + .../mach-tegra/timer.c => drivers/clocksource/tegra20_timer.c | 7 ++----- 7 files changed, 8 insertions(+), 9 deletions(-) rename arch/arm/mach-tegra/timer.c => drivers/clocksource/tegra20_timer.c (98%) diff --git a/arch/arm/Kconfig b/arch/arm/Kconfig index 14f8160..9eb54f6 100644 --- a/arch/arm/Kconfig +++ b/arch/arm/Kconfig @@ -633,6 +633,7 @@ config ARCH_TEGRA select ARCH_HAS_CPUFREQ select CLKDEV_LOOKUP select CLKSRC_MMIO + select CLKSRC_OF select COMMON_CLK select GENERIC_CLOCKEVENTS select GENERIC_GPIO diff --git a/arch/arm/mach-tegra/Makefile b/arch/arm/mach-tegra/Makefile index 6f224f7..6ab3ed5 100644 --- a/arch/arm/mach-tegra/Makefile +++ b/arch/arm/mach-tegra/Makefile @@ -2,7 +2,6 @@ obj-y += common.o obj-y += io.o obj-y += irq.o obj-y += clock.o -obj-y += timer.o obj-y += fuse.o obj-y += pmc.o obj-y += flowctrl.o diff --git a/arch/arm/mach-tegra/board-dt-tegra20.c b/arch/arm/mach-tegra/board-dt-tegra20.c index 794a7bf..0bee85a 100644 --- a/arch/arm/mach-tegra/board-dt-tegra20.c +++ b/arch/arm/mach-tegra/board-dt-tegra20.c @@ -15,6 +15,7 @@ * */ +#include #include #include #include @@ -194,7 +195,7 @@ DT_MACHINE_START(TEGRA_DT, "nVidia Tegra20 (Flattened Device Tree)") .init_early = tegra20_init_early, .init_irq = tegra_dt_init_irq, .handle_irq = gic_handle_irq, - .init_time = tegra_init_timer, + .init_time = clocksource_of_init, .init_machine = tegra_dt_init, .init_late = tegra_dt_init_late, .restart = tegra_assert_system_reset, diff --git a/arch/arm/mach-tegra/board-dt-tegra30.c b/arch/arm/mach-tegra/board-dt-tegra30.c index 08d3b19..a2b6cf1 100644 --- a/arch/arm/mach-tegra/board-dt-tegra30.c +++ b/arch/arm/mach-tegra/board-dt-tegra30.c @@ -23,6 +23,7 @@ * */ +#include #include #include #include @@ -104,7 +105,7 @@ DT_MACHINE_START(TEGRA30_DT, "NVIDIA Tegra30 (Flattened Device Tree)") .init_early = tegra30_init_early, .init_irq = tegra_dt_init_irq, .handle_irq = gic_handle_irq, - .init_time = tegra_init_timer, + .init_time = clocksource_of_init, .init_machine = tegra30_dt_init, .init_late = tegra_init_late, .restart = tegra_assert_system_reset, diff --git a/arch/arm/mach-tegra/board.h b/arch/arm/mach-tegra/board.h index 744cdd2..da8f5a3 100644 --- a/arch/arm/mach-tegra/board.h +++ b/arch/arm/mach-tegra/board.h @@ -55,5 +55,4 @@ static inline int harmony_pcie_init(void) { return 0; } void __init tegra_paz00_wifikill_init(void); -extern void tegra_init_timer(void); #endif diff --git a/drivers/clocksource/Makefile b/drivers/clocksource/Makefile index 29017a3..ecf37f3 100644 --- a/drivers/clocksource/Makefile +++ b/drivers/clocksource/Makefile @@ -16,5 +16,6 @@ obj-$(CONFIG_CLKSRC_NOMADIK_MTU) += nomadik-mtu.o obj-$(CONFIG_CLKSRC_DBX500_PRCMU) += clksrc-dbx500-prcmu.o obj-$(CONFIG_ARMADA_370_XP_TIMER) += time-armada-370-xp.o obj-$(CONFIG_ARCH_BCM2835) += bcm2835_timer.o +obj-$(CONFIG_ARCH_TEGRA) += tegra20_timer.o obj-$(CONFIG_CLKSRC_ARM_GENERIC) += arm_generic.o diff --git a/arch/arm/mach-tegra/timer.c b/drivers/clocksource/tegra20_timer.c similarity index 98% rename from arch/arm/mach-tegra/timer.c rename to drivers/clocksource/tegra20_timer.c index b0036e5..3b2f947 100644 --- a/arch/arm/mach-tegra/timer.c +++ b/drivers/clocksource/tegra20_timer.c @@ -1,6 +1,4 @@ /* - * arch/arch/mach-tegra/timer.c - * * Copyright (C) 2010 Google, Inc. * * Author: @@ -33,8 +31,6 @@ #include #include -#include "board.h" - #define RTC_SECONDS 0x08 #define RTC_SHADOW_SECONDS 0x0c #define RTC_MILLISECONDS 0x10 @@ -168,7 +164,7 @@ static const struct of_device_id rtc_match[] __initconst = { {} }; -void __init tegra_init_timer(void) +static void __init tegra20_init_timer(void) { struct device_node *np; struct clk *clk; @@ -272,6 +268,7 @@ void __init tegra_init_timer(void) #endif register_persistent_clock(NULL, tegra_read_persistent_clock); } +CLOCKSOURCE_OF_DECLARE(tegra20, "nvidia,tegra20-timer", tegra20_init_timer); #ifdef CONFIG_PM static u32 usec_config;
