[PATCH v3 0/4] dw_dmac: return actual residue value

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

The patch series is targeted for getting proper residue value.

Since v2:
 - get rid of dwc_update_residue(): for soft LLP mode we assign residue in
   dwc_do_start() and decrease it at each interrupt. In the middle of transfer
   we will return that result substracted by amount of sent bytes
Since v1:
 - everything is rewritten to address Viresh's and Vinod's comments.

*** BLURB HERE ***

Andy Shevchenko (4):
  dw_dmac: remove unnecessary tx_list field in dw_dma_chan
  dw_dmac: introduce total_len field in struct dw_desc
  dw_dmac: fill individual length of descriptor
  dw_dmac: return proper residue value
