This is an automated instruction, just in case, because many review tags
are being ignored. If you know the process, you can skip it (please do
not feel offended by me posting it here - no bad intentions intended).
If you do not know the process, here is a short explanation:
Please add Acked-by/Reviewed-by/Tested-by tags when posting new
versions, under or above your Signed-off-by tag. Tag is "received", when
provided in a message replied to you on the mailing list. Tools like b4
can help here. However, there's no need to repost patches *only* to add
the tags. The upstream maintainer will do that for tags received on the
version they apply.

Add device tree source for Linksys EA9350 V3 which is a WiFi router based on the IPQ5018 SoC.
As of now , only the UART,USB,USB LED,buttons is working.The front PWM LED require the IPQ PWM driver.Therefore the PWM LED isnt configed in the tree.
Also The original firmware from Linksys can only boot ARM32 kernels.
As of now There seems to be no way to boot ARM64 kernels on those device.
However, it is possible to use this device tree by compiling an ARM32 kernel instead.

Build the Linksys EA9350 V3 device trees from the arm64 tree together with the ARM32 include to allow booting this device on ARM32.
The approach to include device tree files from other architectures is
inspired from e.g. the Raspberry Pi (bcm2711-rpi-4-b.dts) where this is
used to build the device tree for both ARM32 and ARM64.
