+
+                         OMAP GPIO API's HowTo
+                         =====================
+
+This document is a short summary how to use OMAP Linux GPIO API. It is
+mainly focussed on OMAP5912 OSK, but should fit with extensions (more
+or less GPIOs) to other OMAP processors as well.
+
+If anything is missing, is wrong, needs extension or update, please send
+update to [e-mail].
+
+I. GPIO Modules/Banks
+---------------------
+
+OMAP5912 OSK has 64 GPIOs (general purpose IO pins). These are organized
+in four modules (banks) with 16 pins each. OMAP GPIO API doesn't distinguish
+between modules and numbers the pins from 0 - 63:
+
+A) GPIO MODULE/BANK 0 - PIN  0-15
+B) GPIO MODULE/BANK 1 - PIN 16-31
+C) GPIO MODULE/BANK 2 - PIN 32-47
+D) GPIO MODULE/BANK 3 - PIN 48-63
+
+See
+
+http://www-s.ti.com/sc/psheets/spru767a/spru767a.pdf
+
+for more details.
+
+II. GPIO API's
+--------------
+
+A) Include
+
+#include <asm/arch/gpio.h>
+
+B) omap_cfg_reg(xxxx);
+
+Description: Configure pin mux.
+
+Parameter: Pin to be configured for GPIO.
+
+Note: This function may only be necessary for some GPIO pins. Because OMAP
+      chip itself has less real hardware pins than necessary to use all
+      its functionality at the same time, some pins share different
+      functions (called pin multiplexing, short pin mux). E.g. one pin may
+      be used for serial interface *or* GPIO. Check if this is the case for
+      the GPIO you want to use and if you have to configure the pin mux.
+
+C) omap_request_gpio(int gpio)
+
+Description: Request GPIO to be used.
+
+Parameter: int gpio - GPIO PIN (Pin 0-63)
+
+Note: Using this function, you dont have to worry about banks/modules where
+      the gpio pin is.
+
+D) omap_set_gpio_direction(int gpio, int is_input)
+
+Description: This function is responsible for setting the gpio pin direction
+             (input or output).
+
+Parameter: int gpio - GPIO PIN (Pin 0-63)
+           int is_input - pin direction (0 = output, 1 = input)
+
+E) omap_set_gpio_dataout(int gpio, int enable)
+
+Description: This function is responsible for writing to a pin.
+
+Parameter: int gpio - GPIO PIN (Pin 0-63)
+           int enable - pin value (0 or 1)
+
+F) omap_get_gpio_datain(int gpio)
+
+Description: This function is responsible for reading pin values.
+
+Parameter: int gpio - GPIO PIN (Pin 0-63)
+
+G) omap_free_gpio(int gpio)
+
+Description: This function is responsible for freeing the pin used.
+
+Parameter: int gpio - GPIO PIN (Pin 0-63)
+
+H) OMAP_GPIO_IRQ(int gpio)
+
+Description: Returns the Interrupt number for the specified gpio pin.
+
+Parameter: int gpio - GPIO PIN (Pin 0-63)
+
+I) set_irq_type(unsigned int irq, unsigned int type)
+
+Description: This function is responsible for setting the type of interrupt
+             (RISING or FALLING).
+
+Parameter: unsigned int irq - The interrupt number for the gpio pin.
+           unsigned int type - (IRQT_RISING = rising, IRQT_FALLING= falling)
+
+
+III. Example
+------------
+
+1) Writing to gpio pin#3 a value 1 and reading the value of gpio pin#3.
+
+#include <asm/arch/gpio.h>
+
+int ret;                       /* Return value */
+
+omap_request_gpio(3);          /* Request for gpio pin */
+omap_set_gpio_direction(3,0);
+omap_set_set_dataout(3,1);     /* Writing a 1 to gpio pin # 3: */
+ret = omap_get_datain(3);      /* Reading the value of pin # 3 */
+printk("value of pin # 3 = %d\n",ret);
+omap_free_gpio(3);             /* Freeing gpio pin # 3 */
+
+2) Interrupt input by gpio pin#3
+
+#include <asm/arch/gpio.h>
+
+omap_request_gpio(3);         /* Request for gpio pin */
+omap_set_gpio_direction(3,0);
+set_irq_type(OMAP_GPIO_IRQ(3),IRQT_RISING); /* Setting up pin for interrupt */
+request_irq(OMAP_GPIO_IRQ(3), (void *)&my_int_handler, SA_SHIRQ,....);
+
+...                         /* Do stuff, handle interrupts in my_int_handler */
+
+free_irq(OMAP_GPIO_IRQ(3),&id); /*  Freeing interrupt and gpio pin */
+omap_free_gpio(3);
