Set active the IRQ edge(s)/level. This replaces the
SA1111 INTPOL manipulation, and the set_GPIO_IRQ_edge()
- function. Type should be one of the following:
-
- #define IRQT_NOEDGE (0)
- #define IRQT_RISING (__IRQT_RISEDGE)
- #define IRQT_FALLING (__IRQT_FALEDGE)
- #define IRQT_BOTHEDGE (__IRQT_RISEDGE|__IRQT_FALEDGE)
- #define IRQT_LOW (__IRQT_LOWLVL)
- #define IRQT_HIGH (__IRQT_HIGHLVL)
+ function. Type should be one of IRQ_TYPE_xxx defined in
+ <linux/irq.h>
3. set_GPIO_IRQ_edge() is obsolete, and should be replaced by set_irq_type.

+
+Diffconfig is a simple utility for comparing two .config files.
+Using standard diff to compare .config files often includes extraneous and
+distracting information. This utility produces sorted output with only the
+changes in configuration values between the two files.
+
+Added and removed items are shown with a leading plus or minus, respectively.
+Changed items show the old and new values on a single line.
+
+If -m is specified, then output will be in "merge" style, which has the
+changed and new values in kernel config option format.
+
+If no config files are specified, .config and .config.old are used.
+
+Example usage:
+ $ diffconfig .config config-with-some-changes
+-EXT2_FS_XATTR n
+-EXT2_FS_XIP n
+ CRAMFS n -> y
+ EXT2_FS y -> n
+ LOG_BUF_SHIFT 14 -> 16
