Re: [Gumstix-users] gpstix and a/d convertors

[Craig H. <cr...@gu...>]

The A/D on there is coming through the UCB1400.  So you'll want to  
grab the datasheet for that to get the register addresses on the ac97  
bus:

http://www.semiconductors.philips.com/pip/UCB1400-02.html

Then you'll need to tack something onto the ac97 driver, probably  
most easily in the style of the ucb1400-touchscreen driver which is  
in linux/drivers/mfd/ucb1x00* which will let you read from those A/D  
registers on the ucb1400.
