+Subject: [PATCH] ARM: BCM5301X: Add basic dts for BCM53573 based Tenda AC9
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+BCM53573 seems to be low priced alternative for Northstar chipsts. It
+uses single core Cortex-A7 and doesn't have SDU or local (TWD) timer. It
+was also stripped out of independent SPI controller and 2 GMACs.
+
+DTS for Tenda AC9 isn't completed yet. It misses e.g. switch entry (we
+still need some b53 fixes) and probably some clocks. It adds support for
+basic features however and can be improved later.
