+* Algorithm:
+*
+*	The driver sleeps when there is no pen on the screen.  When a pen_down
+*	interrupt occurs, the pen_down interrupt handler wakes the polling thread.
+*	The polling thread polls the ADS chip SAMPLES_PER_SECOND.  When the polling
+*	thread polls the ADS chip and the pen is no longer down, the polling
+*	thread goes to sleep and the pen_down interrupt handler is enabled.
+*
+*	The ADS device sleeps between conversions to save power.
+*
+*	The driver stores pen coordinates in a queue. An application can access
+*	the coordinate queue by opening and reading the associated device file
+*	(char major=10 minor=20).  An application can poll the queue to see if
+*	it contains coordinates. If it does, the application can read a coordinate
+*	structure back. The coordinate queue is flushed when the application
+*	opens the device file.

+* To light up the 7-segment display, write a 16-bit value to
+*
+*	cpld->seven_seg.
+*
+* The high-order byte is the most significant 7-segment digit,
+* and the low-order byte is the lsb.
+*
+* NOTE: The 7-segment display bars are bit-mapped.
+* NOTE: The 7-segment display bars are ACTIVE LOW.
+*
+*     _   ==   a
+*    | |  ==  f b
+*     -   ==   g
+*    | |  ==  e c
+*     -.  ==   d dot
+*
+*    a    0x01

+*    f    0x20
+*    g    0x40
+*    dot  0x80		(also known as dp)
+*
+* The data to write looks like this:
+*
+*	static u_char lednum[] =
+*	{ 0xC0, 0xF9, 0xA4, 0xB0, 0x99, 0x92, 0x82, 0xF8,  // 0-7

+*	  0xBF, // hyphen
+*	  0xFF, // (blank)
+*	};
+*
+* SO - to make "7F" show up, do this:
+*
+*	cpld->seven_seg = 0xf88e;
+*
+* NOTE: When read, the 7-segment display does not return valid data.

+ * Project: ARM IP headers
+ *
+ * Description:
+ *    This file contains the structure definitions and manifest
+ *    constants for ARM IP component:
+ *         General Purpose Input/Output PrimeCell PL060
+ *
+ *         Each GPIO Module has two GPIO (digital IO) ports which are
+ *         designated PORTA and PORTB.
+ *
+ *         Multiple instances of a GPIO module, and thus port pairs,
+ *         may be implemented in a single SOC.
+ *
+ *         Each port has eight bits, PORTx[7:0].
+ *
+ *         Each port has two 8-bit registers associated with it:
+ *             GPIOPxDR - Data register (dr)
+ *             GPIOPxDDR - Data Direction register (ddr)
+ *
+ *         The specific SOC will have its own unique name for the port.
+ *         Each port pair will have its own unique base address for the
+ *         port pair.
+ *
+ *         This include file is designed to permit the definition of 
+ *         pointers in the SOC map include file to distinct 8-bit ports
+ *         using the name designation is suitable for the SOC
+ *         implementation.
+ *
+ *         Example:
+ *         A map file that includes this file should specify a
+ *         base address for each GPIO module, e.g.:
+ *
+ *         #define GPIO0_BASE (0xFFFDF000)
+ *         #define GPIO1_BASE (0xFFFDE000)
+ *             *
+ *             *
+ *             *
+ *
+ *         The SOC map file will use these base addresses to define
+ *         pointers to GPIO port A, B, C, D, E, ... thusly:
+ *
+ *         #define GPIOPA ((volatile GPIOAREGS *)(GPIO0_BASE))
+ *         #define GPIOPB ((volatile GPIOBREGS *)(GPIO0_BASE))
+ *         #define GPIOPC ((volatile GPIOAREGS *)(GPIO1_BASE))
+ *         #define GPIOPD ((volatile GPIOBREGS *)(GPIO1_BASE))
+ *         #define GPIOPE ((volatile GPIOAREGS *)(GPIO2_BASE))
+ *             *
+ *             *
+ *             *
+ *
+ *         Example usage of these definitions in user code for Port C:
+ *
+ *             unsigned int data;
+ *
+ *             GPIOC->ddr = 0xF;    sets bits [7:4] as outputs
+ *                                  and bits [3:0] as inputs
+ *             GPIOC->dr  = 0xF0;   sets bits [7:4] to "1"
+ *
+ *             data = GPIOC->dr;    sets data to the value of
+ *                                  data register
+ *
+ *   Note: If it is desired to use the type qualifier "__packed"
+ *          to enable packing of structures, the manifest constant
+ *          "PACKED" must be defined as follows or as a
+ *          predefine at compilation (ARM-specific notation):
+ *
+ *    #define PACKED __packed
+ *
+ *    If a different compiler/preprocessor is used, the appropriate
+ *    notation must be substituted for "__packed".
+ *

+ *    Revision History:
+ * 
+ *    Rev 1.1   May 17 2001 17:47:58   BarnettH
+ * Changed structure component types to reflect 32-bit access requirements.
