Okay, in what I can only assume is an effort to make finding the
lis302dl (Accelerometer) control interface easier, the path on the SHR
distro I have installed is:
/sys/class/i2c-adapter/i2c-0/0-0073/spi_s3c24xx_gpio.0/spi3.0
/sys/class/i2c-adapter/i2c-0/0-0073/spi_s3c24xx_gpio.0/spi3.1
where the .0 and .1 directories refer to the respective accelerometer
devices.
An alternative path is:
/sys/bus/spi/drivers/lis302dl/spi3.0
/sys/bus/spi/drivers/lis302dl/spi3.1
I don't know who has permission to modify the wiki page, but someone who
can do so may wish to add this information on the #Accelerometers page.
Here is the output of `cat /etc/shr-version` on my machine:
