[PATCH 0/3] Add GPI DMA support for SM6350

[Luca Weiss]

This series hooks up GPI DMA support for the SM6350 I2C.

It has been tested using himax,hxcommon driver that I forward-ported
from the original vendor kernel on fairphone-fp4 - previously I have
used i2c-gpio bitbang in my tree.

This also requires the fix from Robin[0] that has already been
accepted into linux-next, otherwise I2C communication fails to work.

[PATCH 2/3] dmaengine: qcom: gpi: Add SM6350 support

[Luca Weiss]

The Qualcomm SM6350 platform does, like the SM8450, provide a set of GPI
controllers with an ee-offset of 0x10000. Add this to the driver.
