2016-01-21dm: video: Repurpose the 'displayport' uclass to 'display'Simon Glass
The current DisplayPort uclass is too specific. The operations it provides are shared with other types of output devices, such as HDMI and LVDS LCD displays. Generalise the uclass so that it can be used with these devices as well. Adjust the uclass to handle the EDID reading and conversion to display_timing internally. Also update nyan-big which is affected by this. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-01-21video: panel: Add a simple panel driverSimon Glass
Most panels are very simple - they just have a power supply and a backlight. Add a driver which supports this and implements the enable_backlight() method. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-01-21dm: panel: Add a panel uclassSimon Glass
LCD panels can usefully be modelled as their own uclass. They can be probed (which powers them up ready for use). If they have a backlight, this can be enabled. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-01-21dm: backlight: Add a driver for a PWM backlightSimon Glass
Many backlights need to use a PWM to control the brightness. Add a driver for this. It understands the standard device tree binding. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-01-21dm: backlight: Add a backlight uclassSimon Glass
LCD panels normally have a backlight which can be controlled to illuminate the LCD contents. Add a uclass to support this. Initially it only has a method to enable the backlight. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-01-21video: bridge: Allow GPIOs to be optionalSimon Glass
Some video bridges will not have GPIOs to control reset, etc. Allow these to be optional. Signed-off-by: Simon Glass <sjg@chromium.org>

Allow the cache-flushing function of a video device to be controlled. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-01-21video: Name consoles by their numberSimon Glass
We must use the console name in the 'stdout' variable to select the one we want. At present the name is formed from the driver name with a suffix indicating the rotation value. It seems better to name them sequentially since this can be controlled by driver order. So adjust the code to use 'vidconsole' for the first, 'vidconsole1' for the second, etc. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-01-20dm: video: test: Add tests for the video uclassSimon Glass
Add tests that check that the video console is working correcty. Also check that text output produces the expected result. Test coverage includes character output, wrapping and scrolling. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Anatolij Gustschin <agust@denx.de>
2016-01-20dm: video: sandbox: Convert sandbox to use driver model for videoSimon Glass

Move this option to Kconfig. This is quite simple as only sandbox uses the driver. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Anatolij Gustschin <agust@denx.de>
2016-01-20dm: video: Implement the bmp command for driver modelSimon Glass
This command can use the bitmap display code in the uclass. This is similar to the code in lcd.c and cfb_console.c. These other copies will go away when all boards are converted to use driver model for video. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Anatolij Gustschin <agust@denx.de>
2016-01-20dm: video: Add a driver for a rotated text consoleSimon Glass
Sometimes the console must be rotated. Add a driver which supports rotating the text clockwise to 90, 180 and 270 degrees. This can support devices where the display is rotated for mechanical reasons. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Anatolij Gustschin <agust@denx.de>
2016-01-20dm: video: Add a 'normal' text console driverSimon Glass
Most of the time we don't need to rotate the display so a simple font blitting feature is enough for our purposes. Add a simple driver which supports this function. It provides text output on the console using the standard 8x16-pixel font. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Anatolij Gustschin <agust@denx.de>
2016-01-20dm: video: Add a uclass for the text consoleSimon Glass
The existing LCD/video interface suffers from conflating the bitmap display with text output on that display. As a result the implementation is more complex than it needs to me. We can support multiple text console drivers. Create a separate uclass to support this, with its own API. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Anatolij Gustschin <agust@denx.de>
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.

2015-11-19video: Drop unused console functionsSimon Glass
CONFIG_CONSOLE_CURSOR, CONFIG_SYS_CONSOLE_BLINK_COUNT and CONFIG_CONSOLE_TIME are not used by any board. The implementation is not great and stands in the way of a refactor of i8042. Drop these for now. They can be re-introduced quite easily later, perhaps with driver-model real-time-clock (RTC) support. When reintroducing, it might be useful to make a few changes: - Blink time would be more useful than blink count - The confusing #ifdefs should be avoided - The time functions should support driver model - It would be best keyed off console_tstc() or some similar idle loop rather than a particular input driver (i8042 in this case) Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
2015-11-12video: mxsfb: introduce lcdif_power_downPeng Fan
Introudce a new function lcdif_power_down. 1. Waits for a VSYNC interrupt to guarantee the reset is done at the VSYNC edge, which somehow makes the LCDIF consume the display FIFO(?) and helps the LCDIF work normally at the kernel stage. 2. Add power down function to stop lcdif. The reason to introduce lcdif_power_down is that we want lcdif to be in initial state when doing uboot reset or before kernel boot to make system stable, otherwise system may hang.

2015-08-26video: cfb_console: Allow VGA device to work without i8042 keyboardBin Meng
So far if CONFIG_VGA_AS_SINGLE_DEVICE is not defined, the VGA device will try to initialize a keyboard device (for x86, it is i8042). But if i8042 controller initialization fails (eg: there is no keyboard connected to the PS/2 port), drv_video_init() just simply returns. This kills the opportunity of using a usb keyboard later with the vga console, as the vga initialization part is actually ok, only keyboard part fails. Change the code logic to allow this.
