Subject: [PATCH v4 0/3] dmaengine: Add support for QCOM GSI dma controller

This series adds support for Qcom GSI dma controller found on Qualcomm SoCs.
This controller can program the peripheral configuration so we add
additional parameters in dma_slave_config for configuring the peripherals
like spi and i2c.

Changes in v3:
 - Update the i2c tre creation based on testing feedback

Changes in v2:
 - Update the binding and drop qcom specific properties
 - Move peripheral configuration as a pointer
 - Move submit queue for transactions to issue_pending

Vinod Koul (3):
  dt-bindings: dmaengine: Document qcom,gpi dma binding
  dmaengine: add peripheral configuration
  dmaengine: qcom: Add GPI dma driver
