* gpio_cs5535: disable AUX on outputBen Gardner2007-12-051-0/+5
| | | | | | | | | | | | | | | | | The AMD CS5535/CS5536 GPIO has two alternate output modes: AUX-1 and AUX-2. When either AUX is enabled, the cs5535_gpio driver cannot control the output. Some BIOS code for the Geode processor enables AUX-1 for GPIO-1, which configures it as the PC BEEP output. This patch will disable AUX-1 and AUX-2 when the user enables output.

* [PATCH] make more file_operation structs staticArjan van de Ven2006-07-031-1/+1
| | | | | | | | | | | | Mark the static struct file_operations in drivers/char as const. Making them const prevents accidental bugs, and moves them to the .rodata section so that they no longer do any false sharing; in addition with the proper debug option they are then protected against corruption..

| | | | | | | | | | | | | | | | references and other cleanups During module unloading, cdev_del() must be called to unmap cdev related kobject references and other cleanups(such as inode->i_cdev being set to NULL) which prevents the OOPS upon subsequent loading, usage and unloading of modules(as seen in the mail thread http://marc.theaimsgroup.com/?l=linux-kernel&m=114533640609018&w=2). Also, remove unneeded test of gpio_base. Signed-off-by: Thayumanavar Sachithanantham <thayumk@gmail.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] i386: GPIO driver for AMD CS5535/CS5536Ben Gardner2006-01-101-0/+250
A simple driver for the CS5535 and CS5536 that allows a user-space program to manipulate GPIO pins. The CS5535/CS5536 chips are Geode processor companion devices.
