soc: sunxi: Use of_property_present() for testing DT property presence It is preferred to use typed property access functions (i.e. of_property_read_<type> functions) rather than low-level of_get_property/of_find_property functions for reading properties. As part of this, convert of_get_property/of_find_property calls to the recently added of_property_present() helper when we just want to test for presence of a property and nothing more.

soc: sunxi: mbus: Remove DE2 display engine compatibles The DE2 display engine hardware takes physical addresses that do not need PHYS_BASE subtracted. As a result, they should not be present on the mbus driver match list. Remove them. This was tested on the A83T, along with the patch allowing the DMA range map to be non-NULL and restores a working display.

soc: sunxi: Fix compilation of sunxi_mbus dma_direct_set_offset has been moved from dma-mapping.h to dma-map-ops.h, but our driver hasn't been updated resulting in a build breakage. Let's change the header to fix the build.

soc: sunxi: Deal with the MBUS DMA offsets in a central place So far most of the drivers with the MBUS quirks had to duplicate the code to deal with DT compatibility and enforcing the DMA offsets. Let's move for a more maintainable solution by putting everything in a notifier that would take care of setting up the DMA offsets for all the MBUS devices.
