c5c3a468e7 ARM: dts: am57xx-beagle-x15: Add support for rev C
Latest update to the BeagleBoard-X15 platform (revision C). This board contains
a silicon update (Rev 2.0), which includes a fix for the 2nd ethernet phy when
running at 1000 Mbps speeds.

This board can be indentified by the [C.00] after [BBRDX15_] in the at24 eeprom:
[BBRDX15_C.001731PX150249]

Rev C is now in full production and boards are available for end users.

799ab3f4e0 ARM: dts: am57xx-idk: Move common MMC/SD properties to common file
AM572x IDK and AM571x IDK boards have equivalent
design of how SD card and eMMC are connected.

The two EVMs mainly differ in IOdelay configuration
needed (because of difference in SoC used).

Move the common properties to am57xx-idk-common.dtsi
file which is common for both EVMs.

a46394beb0 ARM: dts: dra7xx: Enable NAND dma prefetch by default
Currently the default method of prefetch polled shows the highest
possible read and write speed when minimal non NAND background
activity is being done. But it is also very CPU intensive to reach
these high speeds (CPU load of 99% via mtd performance tests). While
DMA prefetch only uses 50% of the CPU to achieve around 23% less in
top read and write performance.

However, as the non NAND CPU load increases the read and write
performance takes a large hit when using polled prefetch. Therefore,
prefetch dma mode ends up outperforming prefetch polled in general
"system level" test. So switch to using dma prefetch by default since
it is likely what most users would prefer.

3a8ed20db8 ARM: dts: Disable HDMI CEC internal pull-ups
Devices using an external encoder, ESD protection and level shifter
such as tpd12s015 or ip4791cz12 have the CEC pull in the encoder
chip. And on var-som-om44, there is external pull up resistor R30.

So the internal CEC pull-up resistor needs to be disabled as otherwise
the external and internal pull are parallel making the pull value
much smaller than intended. This leads into the CEC not working as
reported by Hans Verkuil <hverkuil@xs4all.nl>.

  Mauro has gone through and fixed up a lot of top-level documentation

  renaming them in any way. This will help when we incorporate the ones
  we want to keep into the Sphinx doctree, but the real purpose is to

eecabf5674 random: suppress spammy warnings about unseeded randomness
Unfortunately, on some models of some architectures getting a fully
seeded CRNG is extremely difficult, and so this can result in dmesg
getting spammed for a surprisingly long time.  This is really bad from
a security perspective, and so architecture maintainers really need to
do what they can to get the CRNG seeded sooner after the system is
booted.  However, users can't do anything actionble to address this,
and spamming the kernel messages log will only just annoy people.

For developers who want to work on improving this situation,
CONFIG_WARN_UNSEEDED_RANDOM has been renamed to
CONFIG_WARN_ALL_UNSEEDED_RANDOM.  By default the kernel will always
print the first use of unseeded randomness.  This way, hopefully the
security obsessed will be happy that there is _some_ indication when
the kernel boots there may be a potential issue with that architecture
or subarchitecture.  To see all uses of unseeded randomness,
developers can enable CONFIG_WARN_ALL_UNSEEDED_RANDOM.
