Currently fbcon claims fbdevs as soon as they are registered and takes over the console as soon as the first fbdev gets registered. This behavior is undesirable in cases where a smooth graphical bootup is desired, in such cases we typically want the contents of the framebuffer (typically a vendor logo) to stay in place as is. The current solution for this problem (on embedded systems) is to not enable fbcon. This commit adds a new FRAMEBUFFER_CONSOLE_DEFERRED_TAKEOVER config option, which when enabled defers fbcon taking over the console from the dummy console until the first text is displayed on the console. Together with the "quiet" kernel commandline option, this allows fbcon to still be used together with a smooth graphical bootup, having it take over the console as soon as e.g. an error message is logged. Note the choice to detect the first console output in the dummycon driver, rather then handling this entirely inside the fbcon code, was made after 2 failed attempts to handle this entirely inside the fbcon code. The fbcon code is woven quite tightly into the console code, making this to only feasible option. Reviewed-by:

drm_of_find_possible_crtcs() doesn't work when DW HDMI encoder is connected to TCON (crtc) through mux in TCON TOP. In that case TCON TOP HDMI mux input port has to be manually traversed and checked if it matches any known crtc. Signed-off-by:

Current "old" method to find engine worked pretty well for DE2. However, it doesn't work when TCON TOP is between mixer (engine) and TCON. TCON TOP has multiple input ports, but current engine search algorithm expects only one. This can be fixed by first looking for output port id and selecting matching input by subtracting 1 for the next round. This work even if there is only one input and output. Signed-off-by:

TV TCONs (channel 1 only) are always connected to TV or HDMI encoder. Because of that, all output endpoints on such TCON node will point to a encoder which is part of component framework. Correct current graph traversing algorithm in such way that it doesn't skip output enpoints with id 0 on TV TCONs. Signed-off-by:

TCON TOP is different from other nodes in graph by having 3 input and 3 output ports. Additionally, connection to TV TCON might lead back to HDMI mux input port, creating loops. Add support for traversing such graph. Signed-off-by:

Until now, each node has one input port and one output port. However, with TCON TOP this is no longer true. It has 3 input and 3 output ports. In order to prepare to this situation, split out the code which checks all endpoints in input port and adds available components to fifo. This patch doesn't do any functional change. Signed-off-by:

As already described in DT binding, TCON TOP is responsible for configuring display pipeline. In this initial driver focus is on HDMI pipeline, so TVE and LCD configuration is not implemented. Implemented features: - HDMI source selection - clock driver (TCON and DSI gating) - connecting mixers and TCONS Something similar also existed in previous SoCs, except that it was part of first TCON.

TCON TOP main purpose is to configure whole display pipeline. It determines relationships between mixers and TCONs, selects source TCON for HDMI, muxes LCD and TV encoder GPIO output, selects TV encoder clock source and contains additional TV TCON and DSI gates. Reviewed-by:

This adds a new binding for Ilitek ILI9341 display panels. It includes a compatible string for one display (more can be added in the future). The YX240QV29-T panel[1] is found, for example, in an Adafruit breakout board[2] and in Mindsensors' PiStorms[3]. The vendor prefix "adafruit" is used because the actual vendor is not known, but Adafruit is the most common source for a product that contains this panel.
