The following patches are updates from n810 tree to
be able to build on top of current linux-omap.
I'm addind here the keypad driver, touchscreen driver,
ambient light sensor driver and LED driver.
Please give it a good review and comments are welcome. I
might have some design issues due to n800 and n810 be using
the same board files, but as of my tests everything works fine.
In case of the LED and ambient light sensor we're gonna
have to test through sysfs.
Here's some notes about both:
- ambient light sensor:
# cat /sys/class/i2c-adapter/i2c-2/2-0029/lux
this will show the light intensity, cover the sensor and it'll change.
- LED driver:
# echo ff:00:00 > /sys/class/i2c-adapter/i2c-2/2-0032/color
this will make the led bright red.
# echo load > /sys/class/i2c-adapter/i2c-2/2-0032/mode
# echo 40000a7f0aff0000 > /sys/class/i2c-adapter/i2c-2/2-0032/load
# echo run > /sys/class/i2c-adapter/i2c-2/2-0032/mode
this will make the LED bright following the pattern in the second echo.
The pattern format is here:
40aabbccbbcc0000
.aa - set pwm [00..ff]
.bb - step time increase brightness [01..3f]short step or [41..7f] long
step
.cc - brightness increment/decrement steps [00..7f] increment or
[80..ff] decrement
.0000 - goto start
note: you can put as much 'bbcc' patterns as you want, i mean:
the following pattern still valid:
# echo 40000a7f0aff137f13ff0c7f0cff0000 > load
That's all, the last patch just updates n800_defconfig to enable these new
drivers.
