51f92c1430 video: Move BMP pixel-writing into a function
At present the code that writes to a pixel is quite convoluted. It uses a
colour map which is in the uclass and the same code is repeated in
different places within video_bmp_display().

As a first step, create a function which can write a pixel from the
bitmap, no matter what the display depth. Use any provided palette
directly, rather than using the uclass version.

56a368f661 gpio: stm32: create include file for driver private data
The stm32 gpio driver private data are not needed in arch include files,
they are not used by code except for stm32 gpio and pincontrol drivers,
using the same IP; the defines for this IP is moved in a new file
"stm32_gpio_priv.h" in driver/gpio.

This patch avoids to have duplicated file gpio.h for each SOC
in MPU directory mach-stm32mp and in each MCU directory arch-stm32*
and allows to remove CONFIG_GPIO_EXTRA_HEADER for all STM32.

1834c081d3 efi: Add video support to the app
The current EFI video driver only works when running in the stub. In that
case the stub calls boot services (before jumping to U-Boot proper) and
copies the graphics info over to the efi table. This is necessary because
the stub exits boot services before jumping to U-Boot.

The app maintains access to boot services throughout its life, so does not
need to do this. Update the driver to support calling boot services
directly.

Enable video output for the app. Note that this uses the
EFI_GRAPHICS_OUTPUT_PROTOCOL protocol, even though it mentions vesa.

A sample qemu command-line for this case is:

   qemu-system-x86_64 -bios /usr/share/edk2.git/ovmf-ia32/OVMF-pure-efi.fd
   -drive id=disk,file=try.img,if=none,format=raw -nic none

2421497cb7 sunxi: video: Convert panel I2C to use DM_I2C
Two displays supported by the sunxi display driver (each one used by a
single board) require initialization over I2C. Both previously used
i2c_soft; replace this with the i2c-gpio instance that already exists in
those boards' device trees (sun5i-a13-utoo-p66 and sun6i-a31-colombus).

Since the i2c-gpio nodes are not referenced by any other node in the
device trees (the device trees have no panel node), the I2C bus is
selected by its node name.

This panel initialization code was the only i2c_soft user, so the
i2c_soft GPIO setup code can be removed now as well.

The only remaining caller of name_to_gpio in generic code is inside the

that code cannot be reached. And after this commit, there are only two

425084610e sunxi: Clean up inclusions of asm/arch/gpio.h
As part of migrating to DM_GPIO and DM_PINCTRL, eventually we will
remove the asm/arch/gpio.h header. In preparation, clean up the various
files that include it.

Some files did not contain any GPIO code at all, so this header was
completely unused.

A few files contained only legacy platform-specific GPIO code for
setting up pin muxes. They were left unchanged, as that code will be
completely removed by the DM_PINCTRL migration.

The remaining files contain some combination of DM_GPIO and legacy GPIO
code. For those, switch to including asm/gpio.h (if it wasn't included
already). Right now, this header provides both sets of functions,
because ARCH_SUNXI selects GPIO_EXTRA_HEADER. This will still be the
right header to include once the DM_GPIO migration is complete and
GPIO_EXTRA_HEADER is no longer needed.

21a151a79d video: Add simple driver for ST-Ericsson MCDE with pre-configured display
The U-Boot port for ST-Ericsson Ux500 is currently only used on the
"stemmy" board, where U-Boot runs after firmware that already sets up
a boot splash screen. This means that the display is already on
and we can just continue using it for U-Boot.

Add a simple driver that simplifies this by reading the display
configuration (e.g. screen size, bpp) from the hardware registers.

It also checks the configured "source synchronization" - for some
displays (usually DSI command mode displays) we need to explicitly
trigger a software sync. This is done through the video_sync()
callback that triggers the sync and wait for completion.

935b5198ef video: sunxi: Use DW-HDMI hpd function
It turns out that there are two ways how hot plug detection can be done.
One is standard way for DW HDMI controller - checking bit 2 in 0x3004
register. Another way is applicable only to Allwinner custom PHY - by
checking bit 19 in register 0x10038. Both methods are equally good as
far as we know.

Use standard method in order to reduce amount of custom code.
