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] 2890/1: OMAP 1/4: Update omap1 specific files, take 2 Patch from Tony Lindgren This patch syncs the mainline kernel with linux-omap tree. The highlights of the patch are: - Convert more drivers to register resources in board-*.c to take advantage of the driver model by David Brownell and Ladislav Michl - Use set_irq_type() for GPIO interrupts instead of omap_set_gpio_edge_ctrl() by David Brownell - Add minimal support for handling optional add-on boards, such as OSK Mistral board with LCD and keypad, by David Brownell - Minimal support for loading functions to SRAM by Tony Lindgren - Wake up from serial port by muxing RX lines temporarily into GPIO interrupts by Tony Lindgren - 32KHz sched_clock by Tony Lindgren and Juha Yrjola Signed-off-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
