The arm dts directory has grown to 1559 boards which makes it a bit
unwieldy to maintain and use. Past attempts stalled out due to plans to
move .dts files out of the kernel tree. Doing that is no longer planned
(any time soon at least), so let's go ahead and group .dts files by
vendors. This move aligns arm with arm64 .dts file structure.
There's no change to dtbs_install as the flat structure is maintained on
install.
The naming of vendor directories is roughly in this order of preference:
- Matching original and current SoC vendor prefix/name (e.g. ti, qcom)
- Current vendor prefix/name if still actively sold (SoCs which have
been aquired) (e.g. nxp/imx)
- Existing platform name for older platforms not sold/maintained by any
company (e.g. gemini, nspire)
The whole move was scripted with the exception of MAINTAINERS and a few
makefile fixups.

The DeviceTree Specification v0.3 specifies that the cache node
'compatible' and 'cache-level' properties are 'required'. Cf.
s3.8 Multi-level and Shared Cache Nodes
The 'cache-unified' property should be present if one of the
properties for unified cache is present ('cache-size', ...).
Update the Device Trees accordingly.

related to existing platforms:
- Airoha (formerly Mediatek/EcoNet) EN7523 networking SoC and EVB
- Mediatek mt6582 tablet platform with the Prestigio PMT5008 3G
tablet
- Microchip Lan966 networking SoC and it evaluation board

all over the place: Samsung, Renesas, Mstar, wpcm450, OMAP, AT91,
Allwinner, i.MX, Tegra, Aspeed, Oxnas, Qualcomm, Mediatek, and
Broadcom.
Samsung has a rework for its pinctrl schema that is a bit tricky and
requires driver changes to be included here.
A few more platforms only have smaller cleanups and DT Schema fixes,
this includes SoCFPGA, ux500, ixp4xx, STi, Xilinx Zynq, LG, and Juno.

- ASRock ROMED8HM3 (AST2500)
Broadcom:
- Raspberry Pi Zero 2 W
Marvell MVEBU/Armada:

- Numerous i.MX8M Mini based boards in even more variations, but
none based on other SoCs this time:
Protonic PRT8MM, emCON-MX8M Mini, Toradex Verdin, and
Gateworks GW7903

While the HVS has the same context memory size in the BCM2711 than in
the previous SoCs, the range allocated to the registers doubled and it
now takes 16k + 16k, compared to 8k + 16k before.
The KMS driver will use the whole context RAM though, eventually
resulting in a pointer dereference error when we access the higher half
of the context memory since it hasn't been mapped.

PCIE_INTR2 second level interrupt controller and one for its MSI second

As Dave reported:
This seems to have unintended side effects. GIC interrupt 117 is shared
between the standard I2C controllers (i2c-bcm2835) and the l2-intc block
handling the HDMI I2C interrupts.
There is not a great way to share an interrupt between an interrupt
controller using the chained IRQ handler which is an interrupt flow and
another driver like i2c-bcm2835 which uses an interrupt handler
(although it specifies IRQF_SHARED).
Simply revert this change for now which will mean that HDMI I2C will be
polled, like it was before.

Depending on bcm2711's revision its emmc2 controller might have
different DMA constraints. Raspberry Pi 4's firmware will take care of
updating those, but only if a certain alias is found in the device tree.
So, move emmc2 into its own bus, so as not to pollute other devices with
dma-ranges changes and create the emmc2bus alias.

With the introduction of the Raspberry Pi 4 we were forced to explicitly
configure CMA's location, since arm64 defaults it into the ZONE_DMA32
memory area, which is not good enough to perform DMA operations on that
device. To bypass this limitation a dedicated CMA DT node was created,
explicitly indicating the acceptable memory range and size.
That said, compatibility between boards is a must on the Raspberry Pi
ecosystem so this creates a common CMA DT node so as for DT overlays to
be able to update CMA's properties regardless of the board being used.

Raspberry Pi's firmware has a feature to select how much memory to
reserve for its GPU called 'gpu_mem'. The possible values go from 16MB
to 944MB, with a default of 64MB. This memory resides in the topmost
part of the lower 1GB memory area and grows bigger expanding towards the
begging of memory.
It turns out that with low 'gpu_mem' values (16MB and 32MB) the size of
the memory available to the system in the lower 1GB area can outgrow the
interconnect's dma-range as its size was selected based on the maximum
system memory available given the default gpu_mem configuration. This
makes that memory slice unavailable for DMA. And may cause nasty kernel
warnings if CMA happens to include it.
Change soc's dma-ranges to really reflect it's HW limitation, which is
being able to only DMA to the lower 1GB area.

arm64 places the CMA in ZONE_DMA32, which is not good enough for the
Raspberry Pi 4 since it contains peripherals that can only address the
first GB of memory. Explicitly place the CMA into that area.

This adds minimal support for the new Raspberry Pi 4 without the
fancy stuff like GENET, PCIe, xHCI, 40 bit DMA and V3D. The RPi 4 is
available in 3 different variants (1, 2 and 4 GB RAM), so leave the memory
size to zero and let the bootloader take care of it. The DWC2 is still
usable as peripheral via the USB-C port.
Other differences to the Raspberry Pi 3:
- additional GIC 400 Interrupt controller
- new thermal IP and HWRNG
- additional MMC interface (emmc2)
- additional UART, I2C, SPI and PWM interfaces
- clock stretching bug in I2C IP has been fixed
