Subject: [PATCH] ARM: BCM5301X: Specify PHY of USB 2.0 in DT
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Driver for Northstar USB 2.0 PHY was added in 4.7-rc1 by:
commit d3feb4067335 ("phy: bcm-ns-usb2: new driver for USB 2.0 PHY on
Northstar").
It should be used to let EHCI platform driver init PHY.

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 standard Northstar
chipsets. It uses single core Cortex-A7, 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 bgmac/b53 fixes) and probably some clocks. It adds
support for basic features however and can be improved later.
