This patch set adds a new drm driver for Hisilicon Hibmc. Hibmc is a BMC SoC with a display controller intergrated, usually it is used on server for Out-of-band management purpose. In this patch set, we just support basic function for Hibmc display subsystem. Hibmc display subsystem is connected to host CPU by PCIe as blow: +----------+ +----------+ | | PCIe | Hibmc | |host CPU( |<----->| display | |arm64,x86)| |subsystem | +----------+ +----------+ Hardware Detail for Hibmc display subsystem ----------- The display subsystem of Hibmc is show as bellow: +----+ +----+ +----+ +--------+ | | | | | | | | | FB |----->| DE |----->|VDAC|---->|external| | | | | | | | VGA | +----+ +----+ +----+ +--------+ -DE(Display Engine) is the display controller. -VDAC(Video Digital-to-Analog converter) converts the RGB diaital data stream from DE to VGA analog signals. Change History ------------ Changes in v4: -remove unused include files, and include header file when it is needed. -remove unused FLAG in Kconfig: DRM_GEM_CMA_HELPER/DRM_KMS_CMA_HELPER. -remove drm_helper_disable_unused_functions, since we use DRIVER_ATOMIC. Changes in v3: -enable KMS, in v2, only fbdev is enabled. -management video memory with ttm. -add vblank interrupt. -remove drm_connector_register_all() and drm_connector_unregister_all(). -I have a basic test with igt. Changes in v2: -Remove self-defined macros for bit operations. -Remove unused register. -Replace those deprecated functions with new version of them. -use drm_connector_register_all() to register connector after drm_dev_register().
