[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




This patch set is based on slave-dma.git / next branch.
(commit id = ebb3abd4042e2ab5f97c43a6f71b206947255fd6)

Changes from v2:
 - Change descriptor management to store the residue in descriptor instead
   of the channel.
 - Change acceptable any sg_len.
 - Modify usb_dmac_tx_status() to calculate the residue for flight
   descriptors.
 - Remove a local tasklet.
 - Remove #ifdef CONFIG_PM.
 Remarks: No change in patch [1/2].

Changes from v1:
 - Use virt-dma infrastructure instead of local descriptor management.
 - Change acceptable sg_len to 1.
   (because a client driver will use dmaengine_prep_slave_single().)
 - Remove usb_dmac_sleep_{suspend,resume} functions.
 - Add usb_dmac_chan_halt() in usb_dmac_runtime_suspend().
 - Use a tasklet instead of a kernel thread.
 - Add tasklet_kill() in usb_dmac_remove().
 - Fix MODULE_AUTHOR string.
 Remarks: No change in patch [1/2].
