9edefc2776 common: Move some cache and MMU functions out of common.h
These functions belong in cpu_func.h. Another option would be cache.h
but that code uses driver model and we have not moved these cache
functions to use driver model. Since they are CPU-related it seems
reasonable to put them here.

Move them over.

754815b854 video: stm32: remove the compatible "synopsys, dw-mipi-dsi" support
Remove the compatible "synopsys,dw-mipi-dsi" added in U-Boot
(it don't exist in Linux kernel binding); it is only used
to bind the generic synopsys UCLASS_DSI_HOST "dw_mipi_dsi" to
the driver "stm32-display-dsi" UCLASS_VIDEO_BRIDGE

This binding is done in Linux kernel drivers without compatible
(dw_mipi_dsi_bind() is called in bind of driver, for example in
drivers/gpu/drm/rockchip/dw-mipi-dsi-rockchip.c).

This patch does the same in U-Boot driver, the STM32 driver
calls during its bind the function device_bind_driver_to_node
to bind the generic driver "dw_mipi_dsi" at the same address.

This patch reduces the device tree differences
between Linux kernel and U-Boot for stm32mp1 platform.

Tested with v2020.01-rc1 on STM32MP157C-EV1 and STM32MP157C-DK2.

The dependency of driver is clearer and the probe order is guaranteed.

ec3dcea744 video: mxsfb: Configure the clock after eLCDIF reset
Running stress reboot test on a i.MX6ULL evk board with a
custom LCD can lead to splash screen failure (black screen).

After comparing the eLCDIF initialization with the Linux kernel
driver, it was noticed that the eLCDIF reset is the first operation
that needs to be done.

So do like the eLCDIF Linux driver and move the eLCDIF clock
frequency configuration after the eLCDIF reset and just prior to
setting the RUN bit.

With this change applied, no more black screen issues has been
found during overnight reboot stress tests.

Currently we may end up with an LCD clock divider that differs from

Fix this by using DIV_ROUND_UP to calculate the divider.  This works
since the PLL is chosen such that the resulting pixel clock is
never higher than the requested pixel clock.

7035ec3cb3 video/console: Factor out actual character output
In preparation for doing character set translations, factor out the
actual glyph display functionality into a separate function.
This will be used in a subsequent patch.

4422294cbe video/console: Implement ANSI clear line command
There is a standard ANSI terminal escape sequence to clear a whole line
of text. So far the DM_VIDEO console was missing this code.

Detect the sequence and use vidconsole_set_row with the background
colour to fix this omission.

29c158b90d video/console: Implement relative cursor movement ANSI handling
The ANSI terminal escapce sequence standard defines relative cursor
movement commands (ESC [ A-F). So far the DM_VIDEO console code was
ignoring them.

Interpret those sequences and move the cursor by the requested amount of
rows or columns in the right direction. This brings the code on par with
the legacy video console driver (cfb_console).

eabb0725d4 video/console: Implement reverse video ANSI sequence for DM_VIDEO
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.
