From d1df97f2d10654ace3d14a77a2de866ce4cd8d4b Mon Sep 17 00:00:00 2001 From: Joerg Faschingbauer Date: Sat, 18 Jan 2014 23:15:07 +0100 Subject: [PATCH 162/174] bcm2708: select NEED_MACH_GPIO_H makers out there use to use gpio_to_irq() in board setup code. it is necessary that gpio_to_irq() be defined as a macro for this to work. https://github.com/raspberrypi/linux/commit/01464226ac6089bd6a33f9899cc792c2355ebf39, on its way towards devicetree, introduces a switch NEED_MACH_GPIO_H that platforms have to set to get the macro definition of gpio_to_irq() - otherwise, the gpiolib incarnation of gpio_to_irq() is found instead which does not work from board code. define NEED_MACH_GPIO_H to make things work again without any pain for makers (though this clearly is in the way of devicetree). --- arch/arm/Kconfig | 1 + 1 file changed, 1 insertion(+) --- a/arch/arm/Kconfig +++ b/arch/arm/Kconfig @@ -367,6 +367,7 @@ config ARCH_BCM2708 select ARM_AMBA select HAVE_CLK select HAVE_SCHED_CLOCK + select NEED_MACH_GPIO_H select NEED_MACH_MEMORY_H select CLKDEV_LOOKUP select ARCH_HAS_CPUFREQ
