flags member of struct timing was not initialized,
this took to unpredictable behaviour of display flags,
such DISPLAY_FLAGS_HSYNC_HIGH instead of _LOW etc.
Init timing->flags = 0

The LCDC IP-core an be feed from several clock sources, one of those is
a dedicated DPLL for generating a dividable base-clock for this IP-core.
The TRM specifies the maximum input frequency for the LCCD with 200 MHz,
so we must not exceed this value with the PLL frequency (which can lock
much higher).
This patch tries every combination of multipliers and divisors of the
PLL and the IP-core itself for getting as near as possible the the
requested panel->pxl_clk.

The calculation of left space for version string is not correct, should
use VIDEO_COLS not VIDEO_LINE_LEN / 2, otherwise we will get larger space
than actual have and cause string to overlay logo picture.
Also current version string display only supports two lines words at max.
This also causes overlay when the LCD pixel column size is not enough.

These are actually different bits, and since some monitors (Benq BL2420PT)

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

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

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.
