From e691ac2f75b69bee743f0370d79454ba4429b175 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Wed, 4 Jan 2017 18:58:31 +0100 Subject: cfg80211: support ieee80211-freq-limit DT property MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This patch adds a helper for reading that new property and applying limitations of supported channels specified this way. It is used with devices that normally support a wide wireless band but in a given config are limited to some part of it (usually due to board design). For example a dual-band chipset may be able to support one band only because of used antennas. It's also common that tri-band routers have separated radios for lower and higher part of 5 GHz band and it may be impossible to say which is which without a DT info.
