| | | | | | | | | | | | | | | | | | | | | | | | | | In some extreme cases it may be necessary to wait 1.5 seconds or more for a hpd signal to show up (and be able to read edid info), but we do not want to penalize all headless boots with an extra second boot delay, so add a hpd_delay parameter which can be set through the video-mode env. variable. While at it raise the default from 300ms to 500ms as 300 may very well be too low in many cases. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | So far we've been programming the hdmi-encoder to send out dvi data over the hdmi connector. This works well for most devices, including hdmi devices, but not all devices accept dvi data on a hdmi input. Add support for sending proper hdmi data over the hdmi output found on most sunxi boards. This can be turned on by adding monitor=hdmi as option to the video-mode env. variable.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The timings for the modes defined in videomodes.c differ (significantly) from vesa standard timings for these modes. This commit adds a version with the proper std timings for these modes, since I do not want to cause regressions, boards which want to use the standard timings need to define CONFIG_VIDEO_STD_TIMINGS to get the new correct timings. Since there is no std timing for 960x720 this commit uses the timing used by the nvidia video drivers for 960x720, which uses a standard pixelclock of 74.25 MHz rather then the weird 76.335... clock used by the old modes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add pixelclock_khz and refresh fields to ctfb_res_modes: 1) pixelclocks are usually referred to in hz, not picoseconds, and e.g pll-s are also typically programmed in hz, not ps. Converting between the 2 leads to rounding differences, add a pixelclock_khz field to directly store the *exact* pixelclock for a mode, so that drivers do not need to resort to rounding tricks to try and guess the exact pixelclock; 2) The video-mode environment variable, as parsed by video_get_video_mode also contains the vertical refresh rate, add a refresh field, so that the refresh-rate can be matched when parsing the video-mode environment variable.

|/ | | | | | | | | | | | | | | | | | | | | | | | This adds a fixed mode hdmi driver for the sunxi platform. The fixed mode is a relatively safe 1024x768, more complete EDID handling is currently not provided. Only HDMI is supported today. This code is enabled when HPD detects an attached monitor. Current config is such that 8MB is shaved off at the top of the RAM. This avoids several memory handling issues, most significant is the fact that on linux on ARM you are not allowed to remap known RAM as IO. A clued in display driver will be able to recycle this reserved RAM in future though. cfbconsole was chosen as it provides the most important functionality: a working u-boot console, allowing for the debugging of certain issues without the need for a UART.
