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

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.
