+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.

+Subject: [PATCH] ARM: dts: BCM53573: Specify serial console parameters
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This adds baud rate, parity & number of data bits. It's required to get
+serial working correctly.

+Subject: [PATCH] ARM: dts: BCM5301X: Add CPU thermal sensor and zone
+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).
