+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".
