Hi all, My company KISS Intelligent Systems is developing a content distribution platform. Part of this requires the client software to play audio and video. When we started we looked around and couldn't find anything that could quite do what we needed, so we wrote our own. We have decided to open source (LGPL) the library we created. The library is designed to be cross platform, however we

Some Tegra drivers might be complied as kernel modules, and they need the fuse information for initialization. One example is the GK20A Nouveau driver. It needs the GPU speedo value to calculate frequency-voltage table. So export the tegra_sku_info.

This series adds support for reclocking on GK20A. The first two patches touch the clock subsystem to allow GK20A to operate, by making the presence of the thermal and voltage devices optional, and allowing pstates to be provided directly instead of being probed using the BIOS (which Tegra does not have). The last patch adds the GK20A clock device. Arguably the clock can be seen as a stripped-down

Second version of the gk20a clock patches. I have tried to keep the therm and volt devices mandatory in the clock driver, but unfortunately they are too tied to bios to allow this, at least for the moment. Consequently this version is mostly a port of the first version to Ben's tree. Ben, please let me know what I have done wrong in terms of integration to your tree, as the main purpose of
