2009-02-24i2c-dev: Clarify the unit of ioctl I2C_TIMEOUTJean Delvare1-1/+1
The unit in which user-space can set the bus timeout value is jiffies for historical reasons (back when HZ was always 100.) This is however not good because user-space doesn't know how long a jiffy lasts. The timeout value should instead be set in a fixed time unit. Given the original value of HZ, this unit should be 10 ms, for compatibility. Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: Wolfram Sang <w.sang@pengutronix.de>
2007-10-14i2c: Move i2c-dev interfaces to i2c-dev.hDavid Brownell1-2/+29
Move the i2c-dev support into <linux/i2c-dev.h> where it should always have lived. Now <linux/i2c.h> no longer holds stuff related to the optional userspace /dev/i2c-X interface. Improve the descriptions for these ioctl requests. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Jean Delvare <khali@linux-fr.org>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
