Subject: [PATCH v2 0/2] dmaengine: ti: omap-dma: Improved polling support
Date: Tue, 16 Jul 2019 11:24:57 +0300	[thread overview]
Message-ID: <20190716082459.1222-1-peter.ujfalusi@ti.com> (raw)

Hi,

changes since v1:
- New preparation cleanup patch
- Simplified code for the main patch to be easier to read

This series fine-tunes the omap-dma polled memcpy support to be inline with how
the EDMA driver is handling it.

The polled completion can be tested by applying:
https://patchwork.kernel.org/patch/10966499/

and run the dmatest with polled = 1 on boards where sDMA is used.

Or boot up any dra7 family device with display enabled. The workaround for DMM
errata i878 uses polled DMA memcpy.

Regards,
Peter
