The sama5d36ek CMP board is the variant of sama5d3xek board.
It is equipped with the low-power DDR2 SDRAM, PMIC ACT8865 and
some power rail. Its main purpose is used to measure the power
consumption.
The difference of the sama5d36ek CMP dts from sama5d36ek dts is
listed as below.
1. The USB host nodes are removed, that is, the USB host is disabled.
2. The gpio_keys node is added to wake up from the sleep.
3. The LCD isn't supported due to the pins for LCD are conflicted
with gpio_keys.
4. The adc0 node support the pinctrl sleep state to fix the over
consumption on VDDANA.
As said in errata, "When the USB host ports are used in high speed
mode (EHCI), it is not possible to suspend the ports if no device is
attached on each port. This leads to increased power consumption even
if the system is in a low power mode." That is why the the USB host
is disabled.

The sama5d2 SoC has a second DMA controller and can be used just like DMA0.
By default both DMA controllers are configured as "Secure" in
MATRIX_SPSELR so we can use whichever we want in a "single Secure World"
configuration.
Surprisingly the DMA1 has a lower address than DMA0. To avoid confusion
place it after DMA0 node anyway.

Some peripherals are "Programmable Secure" but left as "Secure" by default.
If tried to be connected to Non-Secure DMA controller, the possibility to
leak secure data is prevented so using these peripherals with DMA1 is not
possible with this default configuration (MATRIX_SPSELR registers setup by
bootloader).
Move them to DMA0 which is an "Always-Secure" DMA controller.

Since its introduction, the UAO enable call was broken, and useless.
commit 2a6dcb2b5f ("arm64: cpufeature: Schedule enable() calls instead
of calling them via IPI"), fixed the framework so that these calls
are scheduled, so that they can modify PSTATE.
Now it is just useless. Remove it. UAO is enabled by the code patching
which causes get_user() and friends to use the 'ldtr' family of
instructions. This relies on the PSTATE.UAO bit being set to match
addr_limit, which we do in uao_thread_switch() called via __switch_to().
All that is needed to enable UAO is patch the code, and call schedule().
__apply_alternatives_multi_stop() calls stop_machine() when it modifies
the kernel text to enable the alternatives, (including the UAO code in
uao_thread_switch()). Once stop_machine() has finished __switch_to() is
called to reschedule the original task, this causes PSTATE.UAO to be set
appropriately. An explicit enable() call is not needed.

In commit 23c8a500c2 ("arm64: kernel: use ordinary return/argument
register for el2_setup()"), we stopped using w20 as a global stash of
the boot mode flag, and instead pass this around in w0 as a function
parameter.
Unfortunately, we missed a couple of comments, which still refer to the
old convention of using w20/x20.
This patch fixes up the comments to describe the code as it currently
works.

A few printk calls in arm64 omit a trailing newline, even though there
is no subsequent KERN_CONT printk associated with them, and we actually
want a newline.
This can result in unrelated lines being appended, rather than appearing
on a new line. Additionally, timestamp prefixes may appear in-line. This
makes the logs harder to read than necessary.
Avoid this by adding a trailing newline.
These were found with a shortlist generated by:
$ git grep 'pr\(intk\|_.*\)(.*)' -- arch/arm64 | grep -v pr_fmt | grep -v '\\n"'

Function graph tracer shows negative time (wrap around) when tracing
__switch_to if the nosleep-time trace option is enabled.
Time compensation for nosleep-time is done by an ftrace probe on
sched_switch. This doesn't work well for the following events (with
letters representing timestamps):
A - sched switch probe called for task T switch out
B - __switch_to calltime is recorded
C - sched_switch probe called for task T switch in
D - __switch_to rettime is recorded
If C - A > D - B, then we end up over compensating for the time spent in
__switch_to giving rise to negative times in the trace output.
On x86, __switch_to is not traced if function graph tracer is enabled.
Do the same for arm64 as well.
