Dan, This was in response to a request by Kevin in a previous mail. I did have this driver on a website and the link was included in PowerPC Embedded HOWTO maintained by Graham then. But I dont have that server up anymore and the link is not up to date.
And yes, you were right about the spi interface being very specific. But I do feel that it makes sense for anyone starting to make spi work with their hardware to look at some previous work. I wrote this driver looking at your code for the i2c and some spi work done by Tobias Otto-Adamczak. Thanks, Navin. -----Original Message----- From: Dan Malek [mailto:[EMAIL PROTECTED] Sent: Tuesday, December 18, 2001 4:57 PM To: Navin Boppuri Cc: Kevin Fry; linuxppc-embedded at lists.linuxppc.org Subject: Re: 8xx SPI drivers Navin Boppuri wrote: > I have no website of my own to put this stuff on yet. Just ask to post it on penguinppc.org. There is an embedded section there.....but why do you want to post something like this? I mean, we don't post any of the other drivers or code we do anywhere but in the sources themselves. > Also, I would like to thank Alex for cleaning up my driver and for > actually using it. Keep in mind that SPI designs are very dependent upon the board/product design. Many of the systems that use SPI have external hardware for device selection and control. The generic driver is suitable for clocking bits in/out but often isn't sufficient to make everything work. Due to the timing of SPISEL, I sometimes had to just write a software bit-toggle function to make it work. Thanks. -- Dan ** Sent via the linuxppc-embedded mail list. See http://lists.linuxppc.org/
