Subject: [PATCH v2 1/2] dt-bindings: PCI: qcom: adjust iommu-map for different SoC
Date:   Mon, 20 Nov 2023 08:09:09 +0100
Message-Id: <20231120070910.16697-1-krzysztof.kozlowski@linaro.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

The PCIe controller on SDX55 has five entries in its iommu-map, MSM8998
has one and SDM845 has sixteen, so allow wider number of items to fix
dtbs_check warnings like:

  qcom-sdx55-mtp.dtb: pcie@1c00000: iommu-map: [[0, 21, 512, 1], [256, 21, 513, 1],
    [512, 21, 514, 1], [768, 21, 515, 1], [1024, 21, 516, 1]] is too long
