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!

sh: Only provide a PCLK definition for legacy CPG CPUs. As CPUs are migrated over to more fully-featured clock frameworks of their own and off of the legacy CPG code, they no longer have any real need for defining the PCLK value. The PCLK define in itself is already fairly misleading, as many boards get their input clocks from different sources, making this value fairly arbitrary anyways. Outside of the legacy CPG clock framework, the only place where this value is used is for deriving CLOCK_TICK_RATE, which we set back to the legacy PIT value that it was before the PCLK definitions were added in the first place.

sh: Tidy up duplication in irq/swab/timex.h. The asm-generic versions have some helper definitions that we can use instead, drop our definitions and use those instead. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
