Seems the "generous 2MB space" is no longer enough for SPL on some K3 R5
platforms so let's increase this to 4MB. That matches what we give to
ARM64 SPL, so combine these.

This is v2 of the series I originally posted back in August[1]. The
changes here are that I've dropped the first patch as TI has recently
posted their rework of the driver in question, and I added Svyatoslav's
Reviewed-by tag. The end goal here is that "allyesconfig" will be able
to build (on sandbox).

- Refactor tidss_drv to improve modularity, enabling support for more
display interfaces beyond OLDI in the future
- Add detection and initialization of active OLDI panels using the DT
- Port tidss_oldi.c from the upstream Linux kernel oldi series[0] and
derive several APIs from it to determine the dual link pixel order
- Add tidss_oldi_init() and helper routines to handle OLDI-specific
setup and move related helper routines to tidss_oldi.c

Some framebuffers (i.e MediaTek) do not have regular stride - its line
length is more than the display width by 8 pixels (on MT6878). As such,
introduce the optional stride property, which fixes these framebuffers.

code duplication"
Julien Stephan <[email protected]> says:
Commit 2dcf143398ad ("dm: video: Repurpose the 'displayport' uclass to 'display'")
left the display_read_edid() function unused by mistake.
This series addresses that oversight and introduces a new useful cmd.
Patch 1:
- Refactors display_read_timing() to use the existing
display_read_edid() function, eliminating redundant code.
- Marks display_read_edid() as static since it is not used outside of
the file.
Patch 2:
- Adds a new read_edid command, which can be very useful for debugging
or developing new display drivers.
- As this command uses display_read_edid(), the function is made
non-static again.

Add a new command to read EDID info from connected display.
When applicable EDID can also be retrieved by commands such as:
i2c dev x
i2c edid 0x50
but the new read_edid function relies on the implementation of the
read_edid callback from DISPLAY driver.

The logic for how to handle this video driver is slightly odd. Only in
the case of when CONFIG_VIDEO_LCD_PANEL_EDP_4_LANE_1620M_VIA_ANX9804 is
enabled do we need to have this file built, and otherwise we have a
dummy function in use. Correct the logic by only building this file when
needed.

Looking these drivers over, all of them cannot build without access to
some platform specific header files. Express those requirements in
Kconfig as well. Furthermore, update the logic a bit more to reflect
which parts are optional when other drivers are enabled and which parts
cannot be enabled (meaningfully) by themselves.

Get rid of most globals that are spread around between TU's and place
them in their own structs managed by dm. Device state is now owned by
each driver instance. This design mirrors the Linux IPUv3 driver
architecture.
This work is done in preparation to migrate the driver to the clock
framework. While not the primary intent, this change also enables
multiple IPU instances to exist contemporarily.

If CONFIG_OF_PLATDATA=y , then the udevice has no valid OF node associated
with it and ofnode_valid(node) evaluates to 0. The dev_read_u32_default()
call ultimately reaches ofnode_read_u32_index() which invokes fdt_getprop()
and passes result of ofnode_to_offset(node) as an offset parameter into it.
The ofnode_to_offset(node) returns -1 for invalid node, which leads to an
fdt_getprop(..., -1, ...) invocation, which will crash sandbox with SIGSEGV
because libfdt can not handle negative node offsets without full tree check,
which U-Boot inhibits to keep size lower.
Since i2c_child_post_bind() already calls dev_has_ofnode(dev), reuse the
same call and assign i2c->speed_hz = I2C_SPEED_STANDARD_RATE in case the
device has no valid node associated with it, and do not call any of the
dev_read_*() functions for devices without valid nodes.
