Subject: [PATCH v3 0/5] Add and enable GPI DMA users
Date: Fri, 25 Jun 2021 10:52:08 +0530	[thread overview]
Message-ID: <20210625052213.32260-1-vkoul@kernel.org> (raw)

Hello,

This series adds the GPI DMA in qcom geni spi and i2c drivers.

For this we first need to move GENI_IF_DISABLE_RO to common
headers and then add support for gpi dma in geni drivers.

Also, to reuse the dma-mapping in spi, we add a new field dma_map_dev to
allow controllers to pass a specific device for dma-mapping

Then, we add spi and i2c geni driver changes to support this DMA.

Changes since v2:
- Add core spi patch for dma_map_dev addition
- rework the logic for getting and releasing channels in both driver, also
  ensure proper cleanup
- Fix the comments recieved from Doug and Bjorn
- Add kernel-doc changes for enum geni_se_xfer_mode

Changes since v1:
 - add r-b from Bjorn on patch 1
 - add more details in log for patch 2
 - Fix the comments from Doug and Bjorn for patch3, notable use read, modify
   update for irq registers, use geni_se_irq_clear() for irq, dont update
   single bit registers, add a bit more description for gpi dma etc
