dmaengine/dw_dmac: Divide one sg to many desc, if sg len is greater than DWC_MAX_COUNT If len passed in sg for slave_sg transfers is greater than DWC_MAX_COUNT, then driver programmes controller incorrectly. This patch adds code to handle this situation by allocation more than one desc for same sg. Signed-off-by: Viresh Kumar <viresh.kumar@st.com> Signed-off-by: Vinod Koul <vinod.koul@intel.com>
