This patch does not have a v3, but since it is now part of the same
patchset with the controller and the phy drivers patches, I had to
bump the version to 4.
Latest version was here (v2):
https://lore.kernel.org/all/20230118230526.1499328-3-abel.vesa@linaro.org/
Changes since latest version (v2):
* none
Changes since v1:
* ordered pcie related nodes alphabetically in MTP dts
* dropped the pipe_mux, phy_pipe and ref clocks from the pcie nodes
* dropped the child node from the phy nodes, like Johan suggested,
and updated to use the sc8280xp binding scheme
* changed "pcie_1_nocsr_com_phy_reset" 2nd reset name of pcie1_phy
to "nocsr"
* reordered all pcie nodes properties to look similar to the ones
from sc8280xp
