30ca20234e sunxi: video: Convert lcdc to use struct display_timing
Video driver for older Allwinner SoCs uses cfb console framework which
in turn uses struct ctfb_res_modes to hold timing informations. However,
DM video framework uses different structure - struct display_timing.

It makes more sense to convert lcdc to use new timing structure because
all new drivers should use DM video framework and older drivers might be
rewritten to use new framework too.

7682736c89 video: Fix crash when scroll screen
After enabling log printing to lcd, when the screen starts
scrolling, system crashes. Log is shown as bellow:

    "Synchronous Abort" handler, esr 0x96000045
    "Synchronous Abort" handler, esr 0x96000045

Checking the source code, we found that the variable "pixels"
gets a wrong value:

    int pixels = VIDEO_FONT_HEIGHT * vid_priv->line_length;

"pixels" here means the value of pixels for a character, rather
than the bytes for a character. So the variable "pixels" is 4
times bigger than it's exact value, which will cause the memory
overflow when the cpu runs the following code:

    for (i = 0; i < pixels; i++)
        *dst++ = clr; <<----

32f26f56b3 video: fsl_dcu_fb: Enable pixel clock after initialization
When enabling the DCU and pixel clock, the test mode is activated
since this is the reset configuration. The test mode immediately
shows a red screen on a LCD. A moment later, the DCU gets
initialized properly.

This patch enables the pixel clock after initialization of the DCU
control register. This avoids this initial flicker on LCD screens.

While at it change the polarity of pixel clock to display samples
data on the rising edge.

cc232a9d07 rockchip: video: Split out HDMI controller code
Designware HDMI controller and phy are used in other SoCs as well. Split
out platform independent code.

DW HDMI has 8 bit registers but they can be represented as 32 bit
registers as well. Add support to select access mode.

EDID reading code use reading by blocks which is not supported by other
SoCs in general. Make it more general using byte by byte approach, which
is also used in Linux driver.

Finally, not all DW HDMI controllers are accompanied with DW HDMI phy.
Support custom phys by making controller code independent from phy code.

1d4ed26faf video: cfb_console: fix 32-bit display on 64-bit architectures
"unsigned long" is a lousy data type when it comes to match peripheral
hardware registers with a fixed size.
Just do the obvious and match a 32-bit display format with an "u32"
data type for casting.
This fixes the logo display on 64-bit architectures, which produced
a black line on the right side of the logo with non-black backgrounds.

b24cf8540a video: mxsfb: Fix reset hang when videomode variable is not present
Currently the system hangs when the 'videomode' variable is not present
and a reset command is issued:

=> setenv videomode
=> saveenv
=> reset

(Board hangs)

lcdif_power_down() assumes that the LCDIF controller has been properly
configured and enabled, which may not be true.

To fix this issue check whether panel.frameAdrs has been initialized and
in case it has not been initialized, do not continue with the LCDIF
powerdown sequence.

Tested on a imx7dsabresd board.
