Revision ce66b032ad7b838bf376e3b1bb4d8bce1a69ee5c authored by Mark Brown on 07 April 2015, 21:26:44 UTC, committed by Linus Torvalds on 07 April 2015, 23:45:33 UTC
dmapool uses struct device in function arguments but relies on an
implicit inclusion to declare struct device causing warnings in some
configurations:

  include/linux/dmapool.h:31:7: warning: 'struct device' declared inside parameter list

Fix this by adding a struct device declaration to the file.

A generic digital 24-port PCI GPIO card can be built out of an ordinary
Brooktree bt848, bt849, bt878 or bt879 based analog TV tuner card. The
Brooktree chip is used in old analog Hauppauge WinTV PCI cards. You can easily
find them used for low prices on the net.

The bt8xx chip does have 24 digital GPIO ports.
These ports are accessible via 24 pins on the SMD chip package.


==============================================
==  How to physically access the GPIO pins  ==
==============================================

The are several ways to access these pins. One might unsolder the whole chip
and put it on a custom PCI board, or one might only unsolder each individual
GPIO pin and solder that to some tiny wire. As the chip package really is tiny
there are some advanced soldering skills needed in any case.

The physical pinouts are drawn in the following ASCII art.
The GPIO pins are marked with G00-G23
