The HDMI node does not have a power supply attached. As a result its
power regulator, VDAC, shuts off on boot and screen loses signal.
This attaches VDAC (vdda_hdmi_dac) to HDMI's vdda-supply.

System restart mechanism has been changed with the introduction
of "kernel restart handler call chain support". The imx2 watchdog
based restart handler has been moved to the driver, and these
restart can be removed from the machine layer.
This patch cleans up the device tree version machine reset init with
mxc_arch_reset_init_dt and removes corresponding .restart handler,
for the .init_machine that can be handled by system default after
removing the mxc_arch_reset_init_dt, the .init_machine is also removed.

Commit c3ae62af8e755 ("tcp: should drop incoming frames without ACK
flag set") was created to mitigate a security vulnerability in which a
local attacker is able to inject data into locally-opened sockets by
using TCP protocol statistics in procfs to quickly find the correct
sequence number.
This broke the RFC5961 requirement to send a challenge ACK in response
to spurious RST packets, which was subsequently fixed by commit
7b514a886ba50 ("tcp: accept RST without ACK flag").
Unfortunately, the RFC5961 requirement that spurious SYN packets be
handled in a similar manner remains broken.
RFC5961 section 4 states that:
... the handling of the SYN in the synchronized state SHOULD be
performed as follows:
1) If the SYN bit is set, irrespective of the sequence number, TCP
MUST send an ACK (also referred to as challenge ACK) to the remote
peer:
<SEQ=SND.NXT><ACK=RCV.NXT><CTL=ACK>
After sending the acknowledgment, TCP MUST drop the unacceptable
segment and stop processing further.
By sending an ACK, the remote peer is challenged to confirm the loss
of the previous connection and the request to start a new connection.
A legitimate peer, after restart, would not have a TCB in the
synchronized state. Thus, when the ACK arrives, the peer should send
a RST segment back with the sequence number derived from the ACK
field that caused the RST.
This RST will confirm that the remote peer has indeed closed the
previous connection. Upon receipt of a valid RST, the local TCP
endpoint MUST terminate its connection. The local TCP endpoint
should then rely on SYN retransmission from the remote end to
re-establish the connection.
This patch lets SYN packets through the discard added in c3ae62af8e755,
so that spurious SYN packets are properly dealt with as per the RFC.
The challenge ACK is sent unconditionally and is rate-limited, so the
original vulnerability is not reintroduced by this patch.

rtc_tm_to_time() does.
After this patch, rtc_time_to_tm() is deprecated and all its call

The kernel uses 32-bit signed value(time_t) for seconds elapsed
1970-01-01:00:00:00, thus it will overflow at 2038-01-19 03:14:08

Ideally, __clocksource_updatefreq_scale, selects the largest shift
value possible for a clocksource. This results in the mult memember of
struct clocksource being particularly large, although not so large
that NTP would adjust the clock to cause it to overflow.
That said, nothing actually prohibits an overflow from occuring, its
just that it "shouldn't" occur.
So while very unlikely, and so far never observed, the value of
(cs->mult+cs->maxadj) may have a chance to reach very near 0xFFFFFFFF,
so there is a possibility it may overflow when doing NTP positive
adjustment
See the following detail: When NTP slewes the clock, kernel goes
through update_wall_time()->...->timekeeping_apply_adjustment():
tk->tkr.mult += mult_adj;
Since there is no guard against it, its possible tk->tkr.mult may
overflow during this operation.
This patch avoids any possible mult overflow by judging the overflow
case before adding mult_adj to mult, also adds the WARNING message
when capturing such case.

Simplify the pool_io_hints code that works to establish a max_sectors
value that is a power-of-2 factor of the thin-pool's blocksize. The
biggest associated improvement is that the DM thin-pool is no longer
concerning itself with the data device's max_hw_sectors when adjusting
max_sectors.
This fixes the relative fragility of the original "dm thin: adjust
max_sectors_kb based on thinp blocksize" commit that only became
apparent when testing was performed using a DM thin-pool ontop of a
virtio_blk device. One proposed upstream patch detailed the problems
inherent in virtio_blk: https://lkml.org/lkml/2014/11/20/611
So even though virtio_blk incorrectly set its max_hw_sectors it actually
helped make it clear that we need DM thinp to be tolerant of any future
Linux driver that incorrectly sets max_hw_sectors.
We only need to be concerned with modifying the thin-pool device's
max_sectors limit if it is smaller than the thin-pool's blocksize. In
this case the value of max_sectors does become a limiting factor when
upper layers (e.g. filesystems) construct their bios. But if the
hardware can support IOs larger than the thin-pool's blocksize the user
is encouraged to adjust the thin-pool's data device's max_sectors
accordingly -- doing so will enable the thin-pool to inherit the
established user-defined max_sectors.

length is the size of the buffer, not the payload. That's set using

The IRQs have to be acknowledged before they are serviced, otherwise some events
may be skipped. Also, acknowledging IRQs just before returning from the handler
doesn't leave enough time for the device to deassert the INTx line, and for
bridges to propagate this change. This resulted in twice the IRQ rate on ARMv6
dual core CPU.

This patch adds hwmod support for ADC on AM43xx. Since clockdomain
and offsets of adc_tsc are different from AM33xx, ADC data has been
directly added to AM43xx hwmod file.

"The biggest change is to rename the filesystem from "overlayfs" to "overlay".
This will allow legacy overlayfs to be easily carried by distros alongside the
new mainline one. Also fix a couple of copy-up races and allow escaping comma
character in filenames."
The last bit is about commas in pathname mount options...

As the ARCH_AT91RM9200 is removed because being !DT, we use
the SOC_AT91RM9200 variant. This option can certainly be removed
once the ST driver is reworked a bit.

Second part of at91rm9200 legacy !DT removal. This is the core !DT support
removal for this Atmel SoC.
Note that from now on, the Kconfig.non_dt file and its specialized options are
completely removed.
Use the Device Tree for running this board with newer kernels.
