To me, you gave around 18h, through most of the time I was offline or sleeping, and then sent new version. NAK, implement the feedback and keep discussing in the previous version.

Document the PCIe controller on IPQ5332 platform. IPQ5332 will use IPQ9574 as the fall back compatible. All DT entries except "reg" is similar between ipq5332 and ipq9574. ipq9574 has 5 registers while ipq5332 has 6. MHI is the additional (i.e. sixth entry). Since this matches with the sdx55's "reg" definition which allows for 5 or 6 registers, combine ipq9574 and ipq5332 with sdx55. Without this dt_binding_check fails. Signed-off-by: Varadarajan Narayanan <quic_varada@quicinc.com> --- v6: Commit message update only. Add info regarding the moving of ipq9574 from 5 "reg" definition to 5 or 6 reg definition. v5: Re-arrange 5332 and 9574 compatibles to handle fallback usage in dts v4: * v3 reused ipq9574 bindings for ipq5332. Instead add one for ipq5332 * DTS uses ipq9574 compatible as fallback. Hence move ipq9574 to be able to use the 'reg' section for both ipq5332 and ipq9574. Else, dtbs_check and dt_binding_check flag errors. --- Documentation/devicetree/bindings/pci/qcom,pcie.yaml | 10 ++++++++-- 1 file changed, 8 insertions(+), 2 deletions(-)
