[v3,0/5] Add and enable GPI DMA users

Message

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

Thanks!

[3/5] spi: core: add dma_map_dev for dma device
      commit: b470e10eb43f19e08245cd87dd3192a8141cfbb5

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
