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. Signed-off-by: Rafał Miłecki <rafal@milecki.pl>master

Subject: [PATCH] ARM: BCM5301X: Set 5 GHz wireless frequency limits on Netgear
|
||||
R8000
|
||||
MIME-Version: 1.0

||||
Content-Type: text/plain; charset=UTF-8

|
||||
|
||||
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.
