2020-11-18	soc: sunxi: Deal with the MBUS DMA offsets in a central place	Maxime Ripard
	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.

2015-06-01	drivers: soc: sunxi: Introduce SoC driver to map SRAMs	Maxime Ripard
	The Allwinner SoCs have a handful of SRAM that can be either mapped to be accessible by devices or the CPU. That mapping is controlled by an SRAM controller, and that mapping might not be set by the bootloader, for example if the device wasn't used at all, or if we're using solutions like the U-Boot's Falcon Boot. We could also imagine changing this at runtime for example to change the mapping of these SRAMs to use them for suspend/resume or runtime memory rate change, if that ever happens. These use cases require some API in the kernel to control that mapping, exported through a drivers/soc driver. This driver also implement a debugfs file that shows the SRAM found in the system, the current mapping and the SRAM that have been claimed by some drivers in the kernel.
