Main changes introduced by this patchset are: - Formatting fixes - Logical Fixes - Support for Peripheral as flow controller - Support for sg_len to be greater than 1 for slave transfers - Schedule tasklet for error interrupts - remove pl08x_pre_boundary() routine - support for runtime PM - etc This patchset is tested on SPEAr600 for following tests: - memory to memory copy (using drivers/dma/dmatest, upto 16 threads per channel) - peripheral to memory and vice versa (Peripheral: JPEG) This was rebased on Vinod's slave-dma.git/next, over following patch: commit 1ae105aa7416087f2920c35c3cd16831d0d09c9c Merge: 02f8c6a 5a42fb9 Author: Vinod Koul <vinod.koul@intel.com> Date: Wed Jul 27 20:43:21 2011 +0530 Merge branch 'next' into for-linus-3.0 Hope i haven't missed any review comments. Changes Since V2: - Fix issues in "support runtime PM" patch, and move runtime_get and put routines to more suitable positions. - Reformat debug message in "Changing few prints to dev_dbg from dev_info" - set total_len = 0, for each dsg Changes Since V1: - Dropped many formatting fixes which were added earlier, as they made things look even bad. - Fixed tabbing issues in PATCH "Add prep_single_byte_llis() routine" - Many comments are updated throughout the patchset. - Fixed interrupt handler to report spurious interrupt for channels which are not used. - Clk enabling/disabling done via runtime PM - Complete mask of flow controller is not passed from platform data now, direction is decided at runtime. - pl08x_free_txd() called with locks. - Two new patches are added: - Rearrange inclusion of header files in ascending order - pass (*ptr) to sizeof() instead of (struct xyz) Viresh Kumar (20): ARM: asm/pl080.h: Protect against multiple inclusion of header file dmaengine/amba-pl08x: Resolve formatting issues dmaengine/amba-pl08x: Rearrange inclusion of header files in ascending order dmaengine/amba-pl08x: pass (*ptr) to sizeof() instead of (struct xyz) dmaengine/amba-pl08x: Complete doc comment for struct pl08x_txd dmaengine/amba-pl08x: Remove redundant comment and rewrite original dmaengine/amba-pl08x: Changing few prints to dev_dbg from dev_info dmaengine/amba-pl08x: support runtime PM dmaengine/amba-pl08x: Simplify pl08x_ensure_on() dmaengine/amba-pl08x: No need to check "ch->signal < 0" dmaengine/amba-pl08x: Schedule tasklet in case of error interrupt dmaengine/amba-pl08x: Get rid of pl08x_pre_boundary() dmaengine/amba-pl08x: max_bytes_per_lli is TRANSFER_SIZE * src_width (not MIN(width)) dmaengine/amba-pl08x: Add prep_single_byte_llis() routine dmaengine/amba-pl08x: Align lli_len to max(src.width, dst.width) dmaengine/amba-pl08x: Choose peripheral bus as master bus dmaengine/amba-pl08x: Pass flow controller information with slave channel data dmaengine/amba-pl08x: Add support for sg len greater than one for slave transfers dmaengine/amba-pl08x: Check txd->llis_va before freeing dma_pool dmaengine/amba-pl08x: Call pl08x_free_txd() instead of calling kfree() directly arch/arm/include/asm/hardware/pl080.h | 4 + drivers/dma/amba-pl08x.c | 628 ++++++++++++++++----------------- include/linux/amba/pl08x.h | 30 ++- 3 files changed, 335 insertions(+), 327 deletions(-) -- 1.7.2.2
