https://lore.kernel.org/all/20230203081807.2248625-2-abel.vesa@xxxxxxxxxx/

Changes since v7:
* Added Johan's R-b tag

Changes since v6:
* none

Changes since v5:
* added Krzysztof's R-b tag
* renmaed the no-CSR reset to "phy_nocsr" as discussed off-list with
Bjorn and Johan

Changes since v4:
* constrained resets and reset-names to 1 for every other SoC

Changes since v3:
* increased the allowed number of resets to allow ncsr reset
* added vdda-qref-supply which is used by pcie1_phy node in MTP dts
* added both compatibles to the allOf:if:then clause to constrain the
number of possible clocks to 5

Changes since v2:
* added back the binding compatible update patch

Changes since v1:
* split all the offsets into separate patches, like Vinod suggested
