It has three BCM43602 chipsets -two of them for 5 GHz band. Both seem the same and their firmwares -report the same set of channels. The problem is due to hardware / board -design there are extra limitations that should be respected. - -First PHY should be used for U-NII-2 and U-NII-3. Third PHY should be -used for U-NII-1. Using them in a different way may result in wireless -not working or in noticeably reduced performance. Basic version of this -info was provided by Broadcom employee, then it has been verified by me -using original vendor firmware (which has limitations hardcoded in UI). - -This patch uses recently introduced ieee80211-freq-limit property to -describe these limitations at DT level. - -Referencing PCIe devices in DT required specifying all related bridges. -Below you can see (a bit complex) PCI tree from R8000 that explains all -entries that I needed to put in DT. - -0000:00:00.0 14e4:8012 Bridge Device -└─ 0000:01:00.0 14e4:aa52 Network Controller - -0001:00:00.0 14e4:8012 Bridge Device -└─ 0001:01:00.0 10b5:8603 Bridge Device - ├─ 0001:02:01.0 10b5:8603 Bridge Device - │ └─ 0001:03:00.0 14e4:aa52 Network Controller - ├─ 0001:02:02.0 10b5:8603 Bridge Device - │ └─ 0001:04:00.0 14e4:aa52 Network Controller - ├─ 0001:02:03.0 000d:0000 0x000000 - ├─ 0001:02:04.0 000d:0000 0x000000 - ├─ 0001:02:05.0 000d:0000 0x000000 - ├─ 0001:02:06.0 000d:0000 0x000000 - ├─ (...) - ├─ 0001:02:1d.0 000d:0000 0x000000 - ├─ 0001:02:1e.0 000d:0000 0x000000 - └─ 0001:02:1f.0 000d:0000 0x000000 - -Signed-off-by: Rafał Miłecki <rafal@milecki.pl> -Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> ---- - arch/arm/boot/dts/bcm4709-netgear-r8000.dts | 48 +++++++++++++++++++++++++++++ - arch/arm/boot/dts/bcm5301x.dtsi | 8 +++++ - 2 files changed, 56 insertions(+) - ---- a/arch/arm/boot/dts/bcm4709-netgear-r8000.dts -+++ b/arch/arm/boot/dts/bcm4709-netgear-r8000.dts -@@ -108,6 +108,54 @@ - }; - }; - -+&pcie0 { -+ #address-cells = <3>; -+ #size-cells = <2>; -+ -+ bridge@0,0,0 { -+ reg = <0x0000 0 0 0 0>; -+ -+ #address-cells = <3>; -+ #size-cells = <2>; -+ -+ wifi@0,1,0 { -+ reg = <0x0000 0 0 0 0>; -+ ieee80211-freq-limit = <5735000 5835000>; -+ }; -+ }; -+}; -+ -+&pcie1 { -+ #address-cells = <3>; -+ #size-cells = <2>; -+ -+ bridge@1,0,0 { -+ reg = <0x0000 0 0 0 0>; -+ -+ #address-cells = <3>; -+ #size-cells = <2>; -+ -+ bridge@1,1,0 { -+ reg = <0x0000 0 0 0 0>; -+ -+ #address-cells = <3>; -+ #size-cells = <2>; -+ -+ bridge@1,2,2 { -+ reg = <0x1000 0 0 0 0>; -+ -+ #address-cells = <3>; -+ #size-cells = <2>; -+ -+ wifi@1,4,0 { -+ reg = <0x0000 0 0 0 0>; -+ ieee80211-freq-limit = <5170000 5730000>; -+ }; -+ }; -+ }; -+ }; -+}; -+ - &usb2 { - vcc-gpio = <&chipcommon 0 GPIO_ACTIVE_HIGH>; - }; ---- a/arch/arm/boot/dts/bcm5301x.dtsi -+++ b/arch/arm/boot/dts/bcm5301x.dtsi -@@ -243,6 +243,14 @@ - #gpio-cells = <2>; - }; - -+ pcie0: pcie@12000 { -+ reg = <0x00012000 0x1000>; -+ }; -+ -+ pcie1: pcie@13000 { -+ reg = <0x00013000 0x1000>; -+ }; -+ - usb2: usb2@21000 { - reg = <0x00021000 0x1000>; - |
