	The Linux kenerl driver for AMD gpu currently has a floor value of 12 for brightness settings (AMDGPU_DM_DEFAULT_MIN_BACKLIGHT). AMD indicates they did this because they were concerned with certain panels flickering at lower backlight values. However, for unaffected panels it's desirable to be able to have the panel "turn off" at the lowest backlight setting. The only way to do that is to provide ATIF bindings that indicate backlight range. Option SOC_AMD_COMMON_BLOCK_GRAPHICS_ATIF is added to provide a full range for the backlight setting. If needed, this path can be built upon for fuller support, but for the time being this is the only thing necessary to make the backlight be full range.

2020-04-28	soc/amd/common: Add a common graphics block device driver for AMD SoCs	Furquan Shaikh
	This change adds a common graphics block device driver for AMD SoCs. In follow-up CLs, this driver will be utilized for Picasso. This driver is added to enable ACPI name and SSDT generation for graphics controller.
