From 426ab49b3361474622e492cff949853584e3451f Mon Sep 17 00:00:00 2001 From: Jason Wang Date: Sat, 12 Jun 2010 22:22:39 +0800 Subject: mxc/iomux: add GPIO bank offset for iomux v3 platforms These GPIO bank offsets are useful when define a gpio number. E.G. when GPIO PORTC pin 6 is used for irq request pin of external expanding device, we can define it like: #define EXP_PARENT_IRQ_PIN (GPIO_PORTC + 6) Signed-off-by: Jason Wang Signed-off-by: Sascha Hauer --- arch/arm/plat-mxc/include/mach/iomux-v3.h | 15 +++++++++++++++ 1 file changed, 15 insertions(+) (limited to 'arch/arm/plat-mxc/include') diff --git a/arch/arm/plat-mxc/include/mach/iomux-v3.h b/arch/arm/plat-mxc/include/mach/iomux-v3.h index f2f73d31d5b..0880a4a1aed 100644 --- a/arch/arm/plat-mxc/include/mach/iomux-v3.h +++ b/arch/arm/plat-mxc/include/mach/iomux-v3.h @@ -89,6 +89,21 @@ struct pad_desc { #define PAD_CTL_SRE_FAST (1 << 0) #define PAD_CTL_SRE_SLOW (0 << 0) + +#define MX51_NUM_GPIO_PORT 4 + +#define GPIO_PIN_MASK 0x1f + +#define GPIO_PORT_SHIFT 5 +#define GPIO_PORT_MASK (0x7 << GPIO_PORT_SHIFT) + +#define GPIO_PORTA (0 << GPIO_PORT_SHIFT) +#define GPIO_PORTB (1 << GPIO_PORT_SHIFT) +#define GPIO_PORTC (2 << GPIO_PORT_SHIFT) +#define GPIO_PORTD (3 << GPIO_PORT_SHIFT) +#define GPIO_PORTE (4 << GPIO_PORT_SHIFT) +#define GPIO_PORTF (5 << GPIO_PORT_SHIFT) + /* * setups a single pad in the iomuxer */ -- cgit v1.2.3-70-g09d2
