[PATCH v2 02/13] dmaengine: pl330: Add quirk 'arm,pl330-periph-burst'

2020-06-08 Thread Sugar Zhang
This patch adds the qurik to use busrt transfers only for pl330 controller, even for request with a length of 1. Although, the correct way should be: if the peripheral request length is 1, the peripheral should use SINGLE request, and then notify the dmac using SINGLE mode by src/dst_maxburst
