Hi Amancio,
This is the patches for radio support in the bktr driver.
I decided to do a special ioctl for setting the radio frequency, as having
3 magic numbers in application land is fairly stupid. I've made a small
program to tune the radio (instant clock-radio, just add cron :-).
I've not figured out what the program forgets to initialize in the driver,
if you know, please share.
The modifications to the driver should work for both the Philips FM1216
tuner (which I have) and the FR1216 (for which I have the datasheet).
This is still work in progress. I need to add a couple of ioctl's to help
people writing a radio application.
Are there any extensions to tcl/Tk allowing you to do ioctl's ?
Have a nice day
Flemming
