Greg, Attached (due to email line-wrapping problems) is an updated patch for the Philips PCA9539. I think this one is now ready for inclusion. Thanks, Ben === This is a driver for the PCA9539, a 16 bit digital I/O chip. It uses the new i2c-sysfs interfaces. The patch includes documentation. It depends on the patch that renames "i2c-sysfs.h" to "hwmon-sysfs.h" Signed-off-by: Ben Gardner <bgardner at wabtec.com>
