2019-04-14video/console: Implement reverse video ANSI sequence for DM_VIDEOAndre Przywara
The video console for DM_VIDEO compliant drivers only understands a very small number of ANSI sequences. First and foremost it misses the "reverse video" command, which is used by our own bootmenu command to highlight the selected entry. To avoid forcing people to use their imagination when using the bootmenu, let's just implement the rather simple reverse effect. We need to store the background colour index for that, so that we can recalculate both the foreground and background colour pixel values.

2018-12-03video: Allow driver to specify the line lengthSimon Glass
At present line_length is always calculated in video_post_probe(). But some hardware may use a different line length, e.g. with a 1366-wide display. Allow the driver to set this value if needed. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Anatolij Gustschin <agust@denx.de>
2018-11-20video: Update video_set_default_colors() to support invertSimon Glass
It is useful to be able to invert the colours in some cases so that the text matches the background colour. Add a parameter to the function to support this. It is strange that function takes a private data structure from another driver as an argument. It seems better to pass the device and have the function internally work out how to find its required information. Signed-off-by: Simon Glass <sjg@chromium.org>

2018-10-09sandbox: video: Speed up video outputSimon Glass
At present there are many situations where sandbox syncs the display to the SDL frame buffer. This is a very expensive operation but is only needed every now and then. Update video_sync() so that we can specify whether this operation is really needed. At present this flag is not used on other architectures. It could also be used for reducing writeback-cache flushes but the benefit of that would need to be investigated.

Provide a way for the video console driver to be selected. This is controlled by the video driver's private data.

2016-01-20dm: video: Add a video uclassSimon Glass
U-Boot has separate code for LCDs and 'video' devices. Both now use a very similar API thanks to earlier work by Nikita Kiryanov. With the driver- model conversion we should unify these into a single uclass. Unfortunately there are different features supported by each. This implementation provides for a common set of features which should serve most purposes. The intent is to support: - bitmap devices with 8, 16 and 32 bits per pixel - text console wih white on black or vice versa - rotated text console - bitmap display (BMP format) More can be added as additional boards are ported over to use driver model for video. The name 'video' is chosen for the uclass since it is more generic than LCD. Another option would be 'display' but that would introduce a third concept to U-Boot which seems like the wrong approach. The existing LCD and video init functions are not needed now, so this uclass makes no attempt to implement them.

2014-07-23stdio: Pass device pointer to stdio methodsSimon Glass
At present stdio device functions do not get any clue as to which stdio device is being acted on. Some implementations go to great lengths to work around this, such as defining a whole separate set of functions for each possible device. For driver model we need to associate a stdio_dev with a device. It doesn't seem possible to continue with this work-around approach. Instead, add a stdio_dev pointer to each of the stdio member functions. Note: The serial drivers have the same problem, but it is not strictly necessary to fix that to get driver model running. Also, if we convert serial over to driver model the problem will go away. Code size increases by 244 bytes for Thumb2 and 428 for PowerPC. 22: stdio: Pass device pointer to stdio methods arm: (for 2/2 boards) all +244.0 bss -4.0 text +248.0 powerpc: (for 1/1 boards) all +428.0 text +428.0 Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Marek Vasut <marex@denx.de> Reviewed-by: Marek Vasut <marex@denx.de>
