The v7 of this patch is:
https://lore.kernel.org/all/20230203081807.2248625-2-abel.vesa@linaro.org/

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
