[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 = 739e9c81155e74ca7acfa152eea4e8c055fe35b8)

Changes from v3:
 - Call devm_free_irq() in usb_dmac_chan_remove() to prevent the isr gets
   triggered after this driver have freed up stuff.

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].
