Date: Thu, 11 Sep 2014 14:06:15 +0200 From: Stefan Agner <stefan@...er.ch> To: shawn.guo@...escale.com, kernel@...gutronix.de Cc: festevam@...il.com, jingchang.lu@...escale.com, linux-arm-kernel@...ts.infradead.org, linux-kernel@...r.kernel.org, Stefan Agner <stefan@...er.ch> Subject: [PATCH 2/2] ARM: vf610: Use ARM Global Timer as clocksource Use ARM Global Timer as clocksource instead of the PIT timer. This leaves the PIT timer for other users e.g. the secondary Cortex-M4 core. Also, the Global Timer has double the precission (running at pheripheral clock compared to IPG clock) and a 64-bit incrementing counter register. Signed-off-by: Stefan Agner <stefan@...er.ch> --- Theoretically we could remove the PIT driver now. But we could also enable both drivers, but is having two clock source useful for the Kernel at all? arch/arm/mach-imx/Kconfig | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/arch/arm/mach-imx/Kconfig b/arch/arm/mach-imx/Kconfig index 64161aa..adc77180 100644 --- a/arch/arm/mach-imx/Kconfig +++ b/arch/arm/mach-imx/Kconfig @@ -656,7 +656,8 @@ config SOC_VF610 bool "Vybrid Family VF610 support" select ARM_GIC select PINCTRL_VF610 - select VF_PIT_TIMER + select ARM_GLOBAL_TIMER + select CLKSRC_ARM_GLOBAL_TIMER_SCHED_CLOCK select PL310_ERRATA_769419 if CACHE_L2X0 help -- 2.1.0 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
