The hardware queue scheduling is apparently configured with fixed
priorities, which creates a nasty fairness issue where traffic from one

Work around this issue by forcing all tx packets to go through one CPU,

Subject: net: mvneta: disable MVNETA_CAUSE_PSC_SYNC_CHANGE interrupt
The PSC sync change interrupt can fire multiple times while the link is
down. As this isn't information we make use of, it's pointless having
the interrupt enabled, so let's disable this interrupt.

Subject: sfp: hack: allow marvell 10G phy support to use SFP
Allow the Marvell 10G PHY to register with the SFP bus, so that SFP+
cages can work. This bypasses phylink, meaning that socket status
is not taken into account for the link state. Also, the tx-disable
signal must be commented out in DT for this to work...

Subject: ARM: dts: armada388-clearfog: increase speed of i2c0 to 400kHz
All the devices on I2C0 support fast mode, so increase the bus speed
to match. The Armada 388 is known to have a timing issue when in
standard mode, which we believe causes the ficticious device at 0x64
to appear.

commit f94ffbc2c2a4128c4412bb483d0807722dfb682b
Author: Russell King <rmk+kernel@armlinux.org.uk>
Date: Fri Sep 29 11:23:31 2017 +0100
rtc: armada38x: add support for trimming the RTC
Add support for trimming the RTC using the offset mechanism. This RTC
supports two modes: low update mode and high update mode. Low update
mode has finer precision than high update mode, so we use the low mode
where possible.

+ * The information given in the Armada 388 functional spec is complex.
+ * They give two different formulas for calculating the offset value,
+ * but when considering "Offset" as an 8-bit signed integer, they both
+ * reduce down to (we shall rename "Offset" as "val" here):
+ *
+ * val = (f_ideal / f_measured - 1) / resolution where f_ideal = 32768
+ *
+ * Converting to time, f = 1/t:
+ * val = (t_measured / t_ideal - 1) / resolution where t_ideal = 1/32768
+ *
+ * => t_measured / t_ideal = val * resolution + 1
+ *
+ * "offset" in the RTC interface is defined as:
+ * t = t0 * (1 + offset * 1e-9)
+ * where t is the desired period, t0 is the measured period with a zero
+ * offset, which is t_measured above. With t0 = t_measured and t = t_ideal,
+ * offset = (t_ideal / t_measured - 1) / 1e-9
+ *
+ * => t_ideal / t_measured = offset * 1e-9 + 1
+ *
+ * so:
+ *
+ * offset * 1e-9 + 1 = 1 / (val * resolution + 1)
+ *
+ * We want "resolution" to be an integer, so resolution = R * 1e-9, giving
+ * offset = 1e18 / (val * R + 1e9) - 1e9
+ * val = (1e18 / (offset + 1e9) - 1e9) / R
+ * with a common transformation:
+ * f(x) = 1e18 / (x + 1e9) - 1e9
+ * offset = f(val * R)
+ * val = f(offset) / R
+ *
+ * Armada 38x supports two modes, fine mode (954ppb) and coarse mode (3815ppb).

Some boards like the Turris Omnia have an RTC chip that does not get
initialized. Initializing the RTC at the driver level helps get rid of
bootloader hacks that write special register values.

Subject: ARM: dts: armada-385-linksys: Disable internal RTC
The internal RTC does not work correctly on these Linksys boards based
on Marvell SoCs. For me it only shows Wed Dec 31 23:59:59 1969 and for
others it is off by 3 minutes in 10 minutes running, this was reported
by multiple users. On the Linksys Mamba device the device tree comment
says that no crystal is connected to the internal RTC, this is probably
also true for the other devices.
