Patch series adds DT nodes in order to get PCIe working in J7200.
Also includes couple of fixes for J721e.
v1 of the patch series can be found @ [1]
v2 of the patch series can be found @ [2]
v3 of the patch series can be found @ [3]
Changes from v3:
1) Removed Fixes tag as the patches doesn't have to be backported
Changes from v2:
1) Moved serdes_refclk node out of interconnect node and also replaced
"_" with "-"
Changes from v1:
1) Include only the device tree patches here (the binding patch is sent
separately)
2) Include couple of patches that fixes J721E DTS.

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent up the chain during
the next merge window (or sooner if it is a relevant bug fix), however if
problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying
to this mail.
