This series of patches add the support of DRM/KMS drivers for STMicroelectronics chipsets stih416 and stih407. version 4: - Remove depency between TVout it subdevices HDMI and HDA - Rework and simplify VTG and VTAC code - Fix numbers of typo and indentation - Remove debug (will be push in separate patches) - Fix remarks done in previous patcheset patches could be found here: git://git.linaro.org/people/benjamin.gaignard/kernel.git on branch: drm_kms_for_next-v4 version 3: - Correctly split code between probe and bind funtions - Squash some commits - remove HQ-VDP device code to have a smaller patcheset, we will introduce it later. patches could be found here: git://git.linaro.org/people/benjamin.gaignard/kernel.git on branch: drm_kms_for_next-v3 version 2: - Use componentized device instead of register sub-devices in master driver probe function - Fix Makefile and Kconfig to only allow built-in compilation patches could be found here: git://git.linaro.org/people/benjamin.gaignard/kernel.git on branch: drm_kms_for_next-v2 version 1: - First path submission Hardware is split in two main blocks: Compositor and TVout. Each of them includes specific hardware IPs and the display timing are controlled by a specific Video Timing Generator hardware IP (VTG). Compositor is made of the follow hardware IPs: - GDP (Generic Display Pipeline) which is an entry point for graphic (RGB) buffers - VDP (Video Diplay Pipeline) which is an entry point for video (YUV) buffers - HQVDP (High Quality Video Display Processor) that supports scaling, deinterlacing and some miscellaneous image quality improvements. It fetches the Video decoded buffers from memory, processes them and pushes them to the Compositor through a HW dedicated bus. - Mixer is responsible of mixing all the entries depending of their respective z-order and layout TVout is divided in 3 parts: - HDMI to generate HDMI signals, depending of chipset version HDMI phy can change. - HDA to generate signals for HD analog TV - VIP to control/switch data path coming from Compositor On stih416 compositor and Tvout are on different dies so a Video Trafic Advance inter-die Communication mechanism (VTAC) is needed. +---------------------------------------------+ +----------------------------------------+ | +-------------------------------+ +----+ | | +----+ +--------------------------+ | | | | | | | | | | | +---------+ +----+ | | | | +----+ +------+ | | | | | | | | | VIP |---->|HDMI| | | | | |GPD +------------->| | | | | | | | | | | | +----+ | | | | +----+ |Mixer |--|-->| | | | | |---|->| switcher| | | | | | | | | | | | | | | | | +----+ | | | | | | | | | | | | | | | |---->|HDA | | | | | +------+ | |VTAC|========>|VTAC| | +---------+ +----+ | | | | | | | | | | | | | | | | Compositor | | | | | | | | TVout | | | +-------------------------------+ | | | | | | +--------------------------+ | | ^ | | | | | | ^ | | | | | | | | | | | | +--------------+ | | | | | | +-------------+ | | | VTG (master) |----->| | | | | |----->| VTG (slave) | | | +--------------+ +----+ | | +----+ +-------------+ | |Digital die | | Analog Die| +---------------------------------------------+ +----------------------------------------+ On stih407 Compositor and Tvout are on the same die +-----------------------------------------------------------------+ | +-------------------------------+ +--------------------------+ | | | | | +---------+ +----+ | | | | +----+ +------+ | | | VIP |---->|HDMI| | | | | |GPD +------------->| | | | | | +----+ | | | | +----+ |Mixer |--|--|->| switcher| | | | | +----+ +-----+ | | | | | | +----+ | | | | |VDP +-->+HQVDP+--->| | | | | |---->|HDA | | | | | +----+ +-----+ +------+ | | +---------+ +----+ | | | | | | | | | | Compositor | | TVout | | | +-------------------------------+ +--------------------------+ | | ^ ^ | | | | | | +--------------+ | | | VTG | | | +--------------+ | |Digital die | +-----------------------------------------------------------------+ In addition of the drivers for the IPs listed before a thin I2C driver (hdmiddc) is used by HDMI driver to retrieve EDID for monitor. To unify interfaces of GDP and VDP we create a "layer" interface called by compositor to control both GPD and VDP. Hardware have memory contraints (alignment, contiguous) so we use CMA drm helpers functions to allocate frame buffer. File naming convention is: - sti_* for IPs drivers - sti_drm_* for drm functions implementation.
