This series adds initial support for the Khadas VIM 5, a board based
on the Amlogic A311Y3 SoC.

The first patch documents the board compatible. The second adds the
board device tree with UART B enabled, an 8 GiB memory description,
and the ARM Trusted Firmware reserved memory region.

The board has been boot-tested up to initramfs using the serial
console.

The Khadas VIM 5 uses the Amlogic A311Y3 SoC, based on the Amlogic A9
SoC family, on a board with the same form factor as the
VIM/VIM2/VIM3/VIM4/VIM1S models. The serial debug console works with this
initial device tree.

It features:
 - 8GB LPDDR5
 - 64GB eMMC 5.1 storage
 - 32MB SPI flash
 - 10/100/1000 Base-T Ethernet
 - AP6275P Wireless (802.11 a/b/g/n/ac/ax, BT5.1)
 - HDMI 2.1 output
 - HDMI 2.1 input
 - 1x USB 2.0 + 1x USB 3.0 ports
 - 1x USB-C with USB 3.0/DP/PD
 - 2x LEDs (1x red, 1x white)
 - 3x buttons (power, function, reset)
 - M2 socket with PCIe, USB, ADC & I2C
 - 1x 4 lanes MIPI DSI
 - 1x 4 lanes MIPI CSI
 - 40pin GPIO Header
 - 1x micro SD card slot

Thanks, Applied to https://git.kernel.org/pub/scm/linux/kernel/git/amlogic/linux.git (v7.5/arm64-dt)

[1/2] dt-bindings: arm: amlogic: Add Khadas VIM 5

      https://git.kernel.org/amlogic/c/56d1180882a32c78a6207b5364e43c2fc546cd9d

These changes has been applied on the intermediate git tree [1].

The v7.5/arm64-dt branch will then be sent via a formal Pull Request to the Linux SoC maintainers
for inclusion in their intermediate git branches in order to be sent to Linus during
the next merge window, or sooner if it's a set of fixes.

In the cases of fixes, those will be merged in the current release candidate
kernel and as soon they appear on the Linux master branch they will be
backported to the previous Stable and Long-Stable kernels [2].

The intermediate git branches are merged daily in the linux-next tree [3],
people are encouraged testing these pre-release kernels and report issues on the
relevant mailing-lists.

If problems are discovered on those changes, please submit a signed-off-by revert
patch followed by a corrective changeset.
