-Subject: [PATCH 02/13] i2c: qup: fixed releasing dma without flush operation
- completion
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-The QUP BSLP BAM generates the following error sometimes if the
-current I2C DMA transfer fails and the flush operation has been
-scheduled
-
- “bam-dma-engine 7884000.dma: Cannot free busy channel”
-
-If any I2C error comes during BAM DMA transfer, then the QUP I2C
-interrupt will be generated and the flush operation will be
-carried out to make I2C consume all scheduled DMA transfer.
-Currently, the same completion structure is being used for BAM
-transfer which has already completed without reinit. It will make
-flush operation wait_for_completion_timeout completed immediately
-and will proceed for freeing the DMA resources where the
-descriptors are still in process.
