This specifies wireless limitations for Netgear R8000 making sure people
won't use channels incorrectly (limited performance). There are also 2
new DTS files not used by us yet.

+Subject: [PATCH] ARM: BCM5301X: Set 5 GHz wireless frequency limits on Netgear
+ R8000
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Netgear R8000 is a tri-band home router. 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.
