----------------------+-----------------------------------------------------
Apparently, in kernel 2.6.28, the sysfs path for the power control of the
LCD backlight changed from
/sys/devices/platform/s3c2440-i2c/i2c-
adapter/i2c-0/0-0073/backlight/pcf50633-bl
to
/sys/devices/platform/s3c2440-i2c/i2c-
adapter:i2c-0/0-0073/pcf50633-regltr.9/glamo3362.0/glamo-spi-gpio.0/spi2.0
/generic-bl.1/backlight:gta02-bl
or to
/sys/bus/platform/devices/generic-bl.1/backlight:gta02-bl
In any case, the backlight cannot controlled anymore using the old path.
Thus, ompower (as of
http://svnweb.openmoko.org/developers/raster/ompower/power.c?rev=4602&view=auto
) needs to be updated. Until then, the brightness cannot be controlled
under the new kernel.
