[PATCH v2 07/10] ARM: tegra: tf701t: Fix BCM43341 WiFi/BT chip configuration

Newsgroups org.kernel.vger.linux-tegra,org.kernel.vger.linux-devicetree,org.kernel.vger.linux-kernel
Message-ID <[email protected]>
Drop reset GPIO from bluetooth part. Add lpo clock to both WiFi and
bluetooth nodes. Add 'brcm,bcm43340-fmac' as primary compatible and
'brcm,bcm4329-fmac' remains as fallback.
