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] 2836/1: Cleanup IXP4xx GPIO code Patch from Deepak Saxena This patch implements the set_irq_type() hooks for configuring GPIO IRQ type and updates all the platforms to use it instead of the gpio_line_config() function which is now used to configure input vs. output on the pins.
