https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=195009 Ian Lepore <ian@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|Needs Triage |In Discussion CC| |ian@FreeBSD.org --- Comment #1 from Ian Lepore <ian@FreeBSD.org> --- This isn't a great fix since the bus can actually run faster than 400KHz. The real problem is that we've long lacked a way of configuring the speed of each i2c bus in a system, so I attacked the problem from that angle. The patchset is available for review or download here at https://reviews.freebsd.org/D1174 This will allow you to set the bus speed from device hints, from the FDT data, or from a loader.conf file using for example dev.iicbus.0.frequency=400000, or it can be changed on the fly using a sysctl with the same oid/path. -- You are receiving this mail because: You are the assignee for the bug.
