The infinity2m series of chips are like the other Mstar/Sigmastar
chips in that they have a Cortex A7 system with DDR memory integrated
in a single package.
The infinity2m chips are intended for recording the incoming streams
from IP cameras. So instead of video encoders they have video decoders,
instead of a camera interface they have display hardware and so on.
Aside from the above points the big difference about these chips is that
they include a second Cortex A7 core.

Qualcomm ARM64 DT updates for 5.11
For SM8250 the recently introduced support for handling boot-loader
stream mappings in the ARM SMMU allow us to enable this, and thereby USB
controller and PHY, SDHCI controller and FastRPC, as well as support for
the SM8250 HDK board has been added. Additionally PRNG and RTC is
enabled.
Similarly for SM8150, the ARM SMMU could be added which allows the
secondary USB controller and PHYs, as well as WiFi to be added and
support for the SM8150 HDK board to be introduced. Additionally
Coresight and support for the last-level cache controller was added.
MSM8916 finally has VDDCX and VDDMX removed as regulators and are now
handled by the rpmpd driver for the devices controlling them. The
Longsheer L8150 gains touchscreen, sensors, vibrator and LED support.
MSM8992 gains USB and SDHCI support as well as an I2C controller and the
associated RMI4 based touchscreen for the Lumia 950.
MSM8994 also gains USB and SDHCI support, as well as VADC and temp-alarm
support. Then support for the Lumia 950 XL is added.
SDM845 gains interconnect properties for a number of devices and the
GENI wrappers gains iommu stream configuration, which means DMA
operations on e.g. I2C now works. The Lenovo Yoga C630 finally has the
SMMU enabled, a few fixes and the description of the eDP bridge and
panel means that the laptop can now boot mainline with working display,
GPU, WiFi and audio.
SC7180 gains a slew of smaller improvements and fixes.

- Vivek updates the Linksys EA9500 DTS by adding the two additional
switch port nodes (5 & 7), providing a flash partition layout to

- Serge fixes the USB Device Tree nodes unit name to be conformant to
the recommended name patterns.
- Rafal re-arranges all the nodes that belonged to the CRU block to be
under the CRU node (such as PLLs). He also disables the USB3 PHY node
for devices that lack USB3 and adds USB3 support to the Luxul XWR-3150
DTS.
- Jonathan drops the incorrect 'io-channel-ranges' from the Cygnus SoC
DTSI.
- Maxime disables the Wi-Fi frequencies (around 2.4GHz) for HDMI on the

For UARTs, the local pull-ups should be on the RX pin, not the TX pin.
UARTs transmit active-low, so a disconnected RX pin should be pulled
high instead of left floating to prevent noise being interpreted as
transmissions.
This gets rid of bogus sysrq events when the UART console is not
connected.
