Message-ID: <46FE5701.2030000@gmx.net> Date: Sat, 29 Sep 2007 15:45:37 +0200 From: Carl-Daniel Hailfinger <c-d.hailfinger.devel.2006@....net> To: spi-devel-general@...ts.sourceforge.net CC: Linux Kernel Mailing List <linux-kernel@...r.kernel.org> Subject: IT8716F SPI driver submission? Hi! I have written a rough code skeleton to be able to use the ITE IT8716F Super I/O chip as SPI host/master. The code works fine in userspace, but the Linux kernel SPI framework looks like it could save me from implementing full support for SPI flash clients/slaves. That's why I'd like to rewrite my code in a manner that's suitable for kernel inclusion. The IT8716F accepts commands byte-wise and does all of the lifting on the SPI bus as well. There are limitations, though: - It can send 1,2,4,5 bytes (including command byte) to the slave and read 0,1,2,3 bytes back. Other values are not possible. - Bus clock rate is either 33 MHz or 16.5 MHz. Is there any driver I can start from as reference?
