2021-10-13	bus: sun50i-de2: Adjust printing error message	Jernej Skrabec	1	-4/+3
	SRAM driver often returns -EPROBE_DEFER and thus this bus driver often prints error message, even if it probes successfully later. This is confusing for users and they often think that something is wrong. Use dev_err_probe() helper for printing error message. It handles -EPROBE_DEFER automatically.

2018-06-28	bus: add bus driver for accessing Allwinner A64 DE2	Icenowy Zheng	1	-0/+48
	The "Display Engine 2.0" (usually called DE2) on the Allwinner A64 SoC is different from the ones on other Allwinner SoCs. It requires a SRAM region to be claimed, otherwise all DE2 subblocks won't be accessible. Add a bus driver for the Allwinner A64 DE2 part which claims the SRAM region when probing.
