From 38f539a608c9a3b40b30f1892bd5f9a38f4e5ffe Mon Sep 17 00:00:00 2001 From: Eric Miao Date: Tue, 20 Jan 2009 12:09:06 +0800 Subject: [ARM] pxa: move common GPIO handling code into plat-pxa 1. add common GPIO handling code into [arch/arm/plat-pxa] 2. common code in moved into , new processors should implement its own , provide the following required definitions and '#include ' in the end: - GPIO_REGS_VIRT for mapped virtual address of the GPIO registers' physical I/O memory - macros of GPLR(), GPSR(), GPDR() for constant optimization for functions gpio_{set,get}_value() (so that bit-bang code can still have tolerable performance) - NR_BUILTIN_GPIO for the number of onchip GPIO - definitions of __gpio_is_inverted() and __gpio_is_occupied(), they can be either macros or inlined functions Signed-off-by: Eric Miao --- arch/arm/plat-pxa/Makefile | 1 + 1 file changed, 1 insertion(+) (limited to 'arch/arm/plat-pxa/Makefile') diff --git a/arch/arm/plat-pxa/Makefile b/arch/arm/plat-pxa/Makefile index dcc3ceaf717f..b837df440483 100644 --- a/arch/arm/plat-pxa/Makefile +++ b/arch/arm/plat-pxa/Makefile @@ -4,3 +4,4 @@ obj-y := dma.o +obj-$(CONFIG_GENERIC_GPIO) += gpio.o -- cgit
