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.
