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] 3444/1: i.MX: Scatter-gather DMA emulation for i.MX/MX1 Patch from Pavel Pisa This patch contains simplified set of changes to add scatter-gather emulation capability into MX1 DMA support. The result should be still usable for next combination of DMA transfers Statter-Gather/linear/2D/FIFO to linear/2D/FIFO and linear/2D/FIFO to Statter-Gather/2D/FIFO The patch corrects channel priority allocation to be compatible with MX1 hardware implementation. Previous code has not been adapted from its PXA original. Signed-off-by: Pavel Pisa <pisa@cmp.felk.cvut.cz> Acked-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
