Subject[PATCH v2 0/6] Fix some bugs and add new feature for Spreadtrum DMA engine

This patch set fixes some DMA engine bugs and adds interrupt support
for 2-stage transfer.

Changes from v1:
- Improve the commit message for patch 1.
- Drop patch 4 from the v1 patch set, and I will create another patch
set to move the fix to the core.

Baolin Wang (3):
dmaengine: sprd: Fix the possible crash when getting descriptor
dmaengine: sprd: Add validation of current descriptor in irq handler
dmaengine: sprd: Add interrupt support for 2-stage transfer

Eric Long (3):
dmaengine: sprd: Fix the incorrect start for 2-stage destination
dmaengine: sprd: Fix block length overflow
dmaengine: sprd: Fix the right place to configure 2-stage transfer
