Btw, given that I assume this is 4.20 material now, any chance we
could merge it through the dma-mapping tree? I have some major changes
pending that would clash if done in a different tree, so I'd rather
get it all together.

Add single-register MMIO gpio driver for complex cases where
only several fields in register belong to GPIO and each GPIO
owns field with different length and on/off values.
Here is the example:
31118 75 0 < bit number

This patch adds documentation of device tree bindings for the Synopsys
GPIO via CREG driver.

As for today etnaviv device doesn't setup dma_mask.
The etnaviv device is a virtual device not represented in DT
so missing dma_mask isn't setup by generic plaform code
(by of_dma_configure function).
Missing dma_mask causes fails in some dma cache ops functions.
For example it causes fails on map
