Subject: [PATCH v4 0/2] Fix unmasking interrupt bit and remove watermark interrupt enablement

This patch series reset STOP_INT_MASK and ABORT_INT_MASK bit and unmask
these interrupt for HDMA.

and also remove enablement of local watermark interrupt enable(LWIE)
and remote watermarek interrupt enable(RWIE) bit to avoid unnecessary
watermark interrupt event.

Testing
-------

Tested on Qualcomm SA8775P Platform.

V3 -> V4:
- convert IRQs unmasking in a clearer way as suggested by Serge.

V2 -> V3:
- convert 'STOP, ABORT' to 'stop, abort' as suggested by Serge
- Added Reviewed-by tag

V1 -> V2:
- Modified commit message and added Fixes, CC tag as suggested by Mani
- reanme done to STOP
- rename DW_HDMA_V0_LIE -> DW_HDMA_V0_LWIE and DW_HDMA_V0_RIE -> DW_HDMA_V0_RWIE

Mrinmay Sarkar (2):
  dmaengine: dw-edma: Fix unmasking STOP and ABORT interrupts for HDMA
  dmaengine: dw-edma: Do not enable watermark interrupts for HDMA
