Message-Id: <1359107283-5274-1-git-send-email-andriy.shevchenko@linux.intel.com> Date: Fri, 25 Jan 2013 11:47:59 +0200 From: Andy Shevchenko <andriy.shevchenko@...ux.intel.com> To: Viresh Kumar <viresh.linux@...il.com>, Vinod Koul <vinod.koul@...el.com>, linux-kernel@...r.kernel.org, spear-devel <spear-devel@...t.st.com> Cc: Andy Shevchenko <andriy.shevchenko@...ux.intel.com> Subject: [PATCH v4 0/4] dw_dmac: return actual residue value The patch series is targeted for getting proper residue value. Since v3: - split dwc_get_residue() from dwc_tx_status and improve locking there - patch 1/4 "dw_dmac: remove unnecessary tx_list field in dw_dma_chan" was amended a bit to simplify patch 4/4 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.
