2016-05-25video: Add an enum for active low/highSimon Glass
This is used for video signals in some drivers so provide a standard way of representing it in an enum. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Anatolij Gustschin <agust@denx.de> Signed-off-by: Minkyu Kang <mk7.kang@samsung.com>
2016-01-30video: Correct 'tor' typo in commentSimon Glass
This should be 'rot', not 'tor'. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-01-30video: Allow selection of the driver and font sizeSimon Glass
Provide a way for the video console driver to be selected. This is controlled by the video driver's private data. This can be set up when the driver is probed so that it is ready for the video_post_probe() method. The font size is provided as well. The console driver may or may not support this depending on its capability. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Anatolij Gustschin <agust@denx.de>

2016-01-21dm: 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>

2012-11-06video: Provide an API to access video parametersStefan Reinauer
Create a basic API to provide access to video parameters such as screen size, and to position the cursor on the screen. Also add a prototype for video_display_bitmap() which was missing.
