ipq40xx: enlarge PCIe BAR size
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".

+Subject: [PATCH] ARM: dts: qcom: ipq4019: enlarge PCIe BAR range
+
+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".
