    Subject[PATCH AUTOSEL 4.19 100/167] ARM: dts: qcom: ipq4019: enlarge PCIe BAR range
    Date
    From: Christian Lamparter <chunkeey@gmail.com>

    [ Upstream commit f3e35357cd460a8aeb48b8113dc4b761a7d5c828 ]

    David Bauer reported that the VDSL modem (attached via PCIe)
    on his AVM Fritz!Box 7530 was complaining about not having
    enough space in the BAR. A closer inspection of the old
    qcom-ipq40xx.dtsi pulled from the GL-iNet repository listed:

    | qcom,pcie@80000 {
    | compatible = "qcom,msm_pcie";
    | reg = <0x80000 0x2000>,
    | <0x99000 0x800>,
    | <0x40000000 0xf1d>,
    | <0x40000f20 0xa8>,
    | <0x40100000 0x1000>,
    | <0x40200000 0x100000>,
    | <0x40300000 0xd00000>;
    | reg-names = "parf", "phy", "dm_core", "elbi",
    | "conf", "io", "bars";

    Matching the reg-names with the listed reg leads to
    <0xd00000> as the size for the "bars".
