Eric Miao 38f539a608 [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 <mach/gpio.h> moved into <plat/gpio.h>, new processors should implement its own <mach/gpio.h>, provide the following required definitions and '#include <plat/gpio.h>' 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 <eric.miao@marvell.com>		2009-03-23 10:11:33 +08:00
