Raw Normal View History

Linux-2.6.12-rc2 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!

[ARM] 3303/1: S3C24XX - add clock enable usage counting Patch from Ben Dooks Move to using an enable count for the shared clocks and protect the clock system using a mutex instead of just disabling IRQs during the clock update. Since there is little more code in the path for non-shared clocks, the enable and disable calls use the same code for each.

[ARM] 3628/1: S3C24XX: add get_rate call to struct clk Patch from Ben Dooks Add a get_rate call to allow an given clock to over-ride the clk_get_rate() call. This provides support for clocks which rely on division of their parent to correctly report their frequency when the parent can also change.
