Subject: [PATCH] ARM: dts: BCM5301X: Specify serial console params in dtsi
files
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
So far every Northstar device we have seen was using the same serial
console params (115200n8). It probably make the most sense to put it in
some proper dtsi files instead of repeating over and over for every
single device. As different boards may use different bootloaders it
seems the safest idea is to use board specific dtsi files.
Just in case some vendor decides to use different UART (parameters) this
can be always easily overwritten.

This adds baud rate, parity & number of data bits. It's required to get
serial working correctly.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
This uses CPU thermal sensor available on every Northstar chipset to
monitor temperature. We don't have any cooling or throttling so only a
critical trip was added.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Northstar devices have MDIO bus that may contain various PHYs attached.
A common example is USB 3.0 PHY (that doesn't have an MDIO driver yet).
