When HDMI is not initialized (e.g. no monitor is plugged), the current
SimpleFB code will still create a broken SimpleFB node.
Detect whether HDMI is initialized when creating SimpleFB node.

As the support of EFI boot on Allwinner H3 is broken, we still need to

Add an option to indicate that the video driver should setup a SimpleFB
node that passes the video framebuffer initialized by U-Boot to the
operating system kernel.
Currently only the Allwinner DE driver uses this option, and the
definition of this option in the sunxi-common.h config header is
converted to an imply of this option from CONFIG_VIDEO_SUNXI.

U-Boot widely uses error() as a bit noisier variant of printf().
This macro causes name conflict with the following line in
include/linux/compiler-gcc.h:
# define __compiletime_error(message) __attribute__((error(message)))
This prevents us from using __compiletime_error(), and makes it
difficult to fully sync BUILD_BUG macros with Linux. (Notice
Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().)
Let's convert error() into now treewide-available pr_err().
Done with the help of Coccinelle, excluing tools/ directory.
The semantic patch I used is as follows:
// <smpl>
@@@@
-error
+pr_err
(...)
// </smpl>

Note that this doesn't differentiate (due to lack of information in
video_priv) between different possible component orders for 32bpp.
But the main user at this point is efi_loader, and GOP expects xBGR
so any video drivers that this is incorrect for already have problems.
(Also, conveniently, this matches what simple-framebuffer bindings
expect for kernels that use the simple-framebuffer DT binding to
take over the bootloader display.)

Not really qcom specific, but for now qcom/lk is the one firmware that
is (afaiu) setting up the appropriate dt node for pre-configured
display. Uses the generic simple-framebuffer DT bindings so this should

The STM32 LTDC display controller provides a parallel digital RGB and
signals for horizontal, vertical synchronization, Pixel Clock and Data
Enable as output to interface directly to a variety of LCD and TFT panels.
The LTDC main features are:
- 24-bit RGB Parallel Pixel Output, Programmable timings & polarity for
HSync, VSync and Data Enable.
- 2 layers with Blending, Color Keying, Window position & size,
Dithering, Background color, Color Look-Up Table (CLUT).
- Supported layer color formats: ARGB8888, RGB888, RGB565, ARGB1555,
ARGB4444, L8 CLUT, AL44 & AL88
This LTDC driver:
- supports: RGB parallel output with timings & polarity, 1 layer
in RGB565.
- supports but with hard-coded configurations: blending, window
position & size (crop), background color.
- does not support yet: rgb888, argb8888, 8-bit clut, dithering.
This LTDC driver is compatible with all stm32 platforms with the
LTDC IP and has been tested on stm32 f746-disco board.

MX6Q/QP IPU operates at 264MHz and MX6DL IPU at 198MHz.
When running a SPL target, which supports multiple MX6 variants we cannot
properly setup the IPU clock frequency via CONFIG_IPUV3_CLK option as
such decision is done in build-time currently.
Remove the CONFIG_IPUV3_CLK option and let the IPU clock frequency be
configured in run-time on mx6.

Boards can skip display interface init using board_video_skip().
If display interface was not initialized (e.g. no ipuv3 framebuffer
registered or IPU clock disabled), booting Linux stops due to the
crash in IPU shutdown function, when accessing IPU registers.
Check IPU clock and skip shutdown if clock is not enabled.

AVR32 is gone. It's already more than two years for no support in Buildroot,
even longer there is no support in GCC (last version is heavily patched 4.2.4).
Linux kernel v4.12 got rid of it (and v4.11 didn't build successfully).
There is no good point to keep this support in U-Boot either.

Add remove() methods for EDP and VOP so that U-Boot can shut down the
video on exit. This avoids leaving DMA running while booting Linux which
can cause problems if Linux uses the frame buffer for something else.
It also makes it clear what is needed to shut down video.
While we are here, make rkvop_enable() static.
