Add GPIO D5 (BT_ENABLE_L) as reset-GPIO to the power sequence for the
Bluetooth/WiFi module. On devices with a Broadcom module the signal
needs to be asserted to use Bluetooth.
Note that BT_ENABLE_L is a misnomer in the schematics, the signal
actually is active-high.

Some veyron devices have a Bluetooth controller connected on UART0.
The UART needs to operate at a high speed, however setting the clock
rate at initialization has no practical effect. During initialization
user space adjusts the UART baudrate multiple times, which ends up
changing the SCLK rate. After a successful initiatalization the clk
is running at the desired speed (48MHz).
Remove the unnecessary clock rate configuration from the DT.

Mighty is basically the same Chromebook as Jaq but it has a full-sized
SD slot and some different (slightly more rugged) plastics around it.
Like Jaq, Mighty may show up with various different brandings but all
of them have the same board inside.
In the downstream kernel Mighty and Jaq share a "dtsi" and Mighty just
adds the SD write protect (needed for a full-sized SD slot). We'll do
this upstream by just including the Jaq dts and make the changes.

The vdd_logic rail controls the voltage supplied to misc logic on
rk3288, including the voltage supplied to the memory controller. The
vcc logic is implemented by a PWM regulator.
Right now there are no consumers of vdd_logic on veyron but if anyone
ever wants to try to add DDR Freq they'd need it.
Note that in the downstream Chrome OS kernel the PWM regulator has
a voltage table with these points:
1350000 0%
1300000 10%
1250000 20%
1200000 31%
1150000 41%
1125000 46%
1100000 52%
1050000 62%
1000000 72%
950000 83%
The DDR Freq driver in the downstream kernel only uses some of those
points, namely:
DDR3: 1200000, 1150000, 1100000, 1050000
LPDDR: 1150000, 1100000, 1050000
When adapting the downstream kernel to upstream I have opted to switch
to using the "continuous" mode of the PWM regulator driver. This was
the only way I could get the upstream driver to achieve _exactly_ the
same voltages as the downstream driver could. Specifically note that
the old driver in downstream Chrome OS 3.14 _didn't_ have the
DIV_ROUND_CLOSEST_ULL() in the Rockchip PLL driver. That means if I
use the same (downstream) table I might end up with a duty cycle
that's 1 larger than was used downstream, leading to a slightly
different voltage. Due to the way the rounding worked I couldn't even
just adjust the "percent" by 1 for a given voltage level--certain duty
cycles just aren't achievable with the upstream math for voltage
tables.
Using continuous mode you can achieve the exact same duty cycle by
simply adjusting the voltage you use by a tad bit. The voltages that
are equivalent to the ones used in the downstream kernel's table are:
1350000, 1304472, 1255691, 1200407, 1154878,
1128862, 1099593, 1050813, 1005285, 950000
Note that the top/bottom voltage is exactly the same just due to the
way that continuous mode is calculated and the fact that I used those
as anchors. I didn't make any attempt to do the resistor math (as was
done on rk3399-gru).
If anyone ever gets DDRFreq working on veyron upstream they should
thus adjust the voltage specified in the DDRFreq operating points
slightly (as per the above) to obtain the existing/tested values. AKA
you'd use:
DDR3: 1200407, 1154878, 1099593, 1050813
LPDDR: 1154878, 1099593, 1050813
A few other notes:
- The "period" here (1994) is different than the "period" downstream
(2000) for similar reasons: there's a DIV_ROUND_CLOSEST_ULL() that
wasn't downstream. With 1994 upstream comes up with the same value
(0x94) to program into the hardware that downstream put there. As
far as I can tell 0x94 actually means 1993.27.
- The duty cycle unit of 0x94 was picked by just matching the period
which nicely allows us to insert 0x7b as that value to program into
the hardware for 950mV. The 0x7b was found by observing what the
downstream kernel calculated (not that the system can actually run
with vdd_log at 950 mV).
- The downstream kernel can also be seen to program a different value
into the CTRL field. Upstream achieves 0x0b and downstream 0x1b.
This is because the upstream commit bc834d7b07b4 ("pwm: rockchip:
Move the configuration of polarity") fixed a bug by adding "ctrl &=
~PWM_POLARITY_MASK". Downstream accidentally left bit 4 set.
Luckily this bit doesn't matter--it's only used when the PWM goes
inactive (AKA if it's in oneshot mode or is disabled) and we don't
do that for the PWM regulator.
I measured the voltage of vdd_log while adjusting it and found that
with the upstream kernel voltage difference between requested and
actual was 9.2 mV at 950 mV and 13.4 mV at 1350 mV with in-between
voltages consistently showing ~1% error. This error is likely
expected as voltage can be seen to sag a bit when more load is put on
the rail.

When the rk3288-jerry device tree was first submitted we left out the
dvs-gpios because I pointed out that the property "dvs-gpios" wasn't
yet supported upstream [1]. Soon after that the property was added in
commit bad47ad2eef3 ("regulator: rk808: fixed the overshoot when
adjust voltage"). ...but we forgot to go back and add the property to
the jerry device tree file. Let's do so now.
NOTE: without this patch, jerry is likely still stable (thanks to the
fallback of making many small jumps in the rk808 regulator code) but
it'll take quite a bit longer to make voltage transitions.

As far as I can tell/remember rev10 was originally created to support
making a SKU of jerry that had a different LCD. rev11-rev15 were
added to give some wiggle room for future builds. Downstream has a
separate device tree for rev10-rev15 (compared to rev3-rev7) with the
expectation that differences relating to the LCD would be accounted
for there but nothing was ever added to the rev10-rev15 making it
identical to the rev3-rev7 one.
It's likely nothing actually shipped with rev10-rev15 but they are
listed in the downstream kernel's device tree and it seems like it
should add a little safety if we match them here just in case
something actually shipped with one of these revisions and that device
will break if we don't claim support.

During a simple no-op (nothing changed) build I saw 39 invocations of
the C compiler with the argument "-print-file-name=include". We don't
need to call the C compiler 39 times for this--one time will suffice.
Let's change NOSTDINC_FLAGS to a simply expanded variable to avoid
this since there doesn't appear to be any reason it should be
recursively expanded.
On my build this shaved ~400 ms off my "no-op" build.
Note that the recursive expansion seems to date back to the (really
old) commit e8f5bdb02ce0 ("[PATCH] Makefile include path ordering").
It's a little unclear to me if the point of that patch was to switch
the variable to be recursively expanded (which it did) or to avoid
directly assigning to NOSTDINC_FLAGS (AKA to switch to +=) because
someone else (out of tree?) was setting it. I presume later since if
the only goal was to switch to recursive expansion the patch would
have just removed the ":".

The of_find_device_by_node() takes a reference to the underlying device
structure, we should release that reference.
The implementation of this semantic code search is:
In a function, for a local variable returned by calling
of_find_device_by_node(),
a, if it is released by a function such as
put_device()/of_dev_put()/platform_device_put() after the last use,
it is considered that there is no reference leak;
b, if it is passed back to the caller via
dev_get_drvdata()/platform_get_drvdata()/get_device(), etc., the
reference will be released in other functions, and the current function
also considers that there is no reference leak;
c, for the rest of the situation, the current function should release the
reference by calling put_device, this code search will report the
corresponding error message.
By using this semantic code search, we have found some object reference leaks,
such as:
commit 11907e9d3533 ("ASoC: fsl-asoc-card: fix object reference leaks in
fsl_asoc_card_probe")
commit a12085d13997 ("mtd: rawnand: atmel: fix possible object reference leak")
commit 11493f26856a ("mtd: rawnand: jz4780: fix possible object reference leak")
There are still dozens of reference leaks in the current kernel code.
Further, for the case of b, the object returned to other functions may also
have a reference leak, we will continue to develop other cocci scripts to
further check the reference leak.

Pull pidfd system call from Christian Brauner:
"This introduces the ability to use file descriptors from /proc/<pid>/
as stable handles on struct pid. Even if a pid is recycled the handle
will not change. For a start these fds can be used to send signals to
the processes they refer to.
With the ability to use /proc/<pid> fds as stable handles on struct
pid we can fix a long-standing issue where after a process has exited
its pid can be reused by another process. If a caller sends a signal
to a reused pid it will end up signaling the wrong process.
With this patchset we enable a variety of use cases. One obvious
example is that we can now safely delegate an important part of
process management - sending signals - to processes other than the
parent of a given process by sending file descriptors around via scm
rights and not fearing that the given process will have been recycled
in the meantime. It also allows for easy testing whether a given
process is still alive or not by sending signal 0 to a pidfd which is
quite handy.
There has been some interest in this feature e.g. from systems
management (systemd, glibc) and container managers. I have requested
and gotten comments from glibc to make sure that this syscall is
suitable for their needs as well. In the future I expect it to take on
most other pid-based signal syscalls. But such features are left for
the future once they are needed.
This has been sitting in linux-next for quite a while and has not
caused any issues. It comes with selftests which verify basic
functionality and also test that a recycled pid cannot be signaled via
a pidfd.
Jon has written about a prior version of this patchset. It should
cover the basic functionality since not a lot has changed since then:

Pull device-dax updates from Dan Williams:
"New device-dax infrastructure to allow persistent memory and other
"reserved" / performance differentiated memories, to be assigned to
the core-mm as "System RAM".
Some users want to use persistent memory as additional volatile
memory. They are willing to cope with potential performance
differences, for example between DRAM and 3D Xpoint, and want to use
typical Linux memory management apis rather than a userspace memory
allocator layered over an mmap() of a dax file. The administration
model is to decide how much Persistent Memory (pmem) to use as System
RAM, create a device-dax-mode namespace of that size, and then assign
it to the core-mm. The rationale for device-dax is that it is a
generic memory-mapping driver that can be layered over any "special
purpose" memory, not just pmem. On subsequent boots udev rules can be
used to restore the memory assignment.
One implication of using pmem as RAM is that mlock() no longer keeps
data off persistent media. For this reason it is recommended to enable
NVDIMM Security (previously merged for 5.0) to encrypt pmem contents
at rest. We considered making this recommendation an actively enforced
requirement, but in the end decided to leave it as a distribution /
administrator policy to allow for emulation and test environments that
lack security capable NVDIMMs.
Summary:
- Replace the /sys/class/dax device model with /sys/bus/dax, and
include a compat driver so distributions can opt-in to the new ABI.
- Allow for an alternative driver for the device-dax address-range
- Introduce the 'kmem' driver to hotplug / assign a device-dax
address-range to the core-mm.
- Arrange for the device-dax target-node to be onlined so that the
newly added memory range can be uniquely referenced by numa apis"
NOTE! I'm not entirely happy with the whole "PMEM as RAM" model because
we currently have special - and very annoying rules in the kernel about
accessing PMEM only with the "MC safe" accessors, because machine checks
inside the regular repeat string copy functions can be fatal in some
(not described) circumstances.
And apparently the PMEM modules can cause that a lot more than regular
RAM. The argument is that this happens because PMEM doesn't necessarily
get scrubbed at boot like RAM does, but that is planned to be added for
the user space tooling.
Quoting Dan from another email:
"The exposure can be reduced in the volatile-RAM case by scanning for
and clearing errors before it is onlined as RAM. The userspace tooling
for that can be in place before v5.1-final. There's also runtime
notifications of errors via acpi_nfit_uc_error_notify() from
background scrubbers on the DIMM devices. With that mechanism the
kernel could proactively clear newly discovered poison in the volatile
case, but that would be additional development more suitable for v5.2.
I understand the concern, and the need to highlight this issue by
tapping the brakes on feature development, but I don't see PMEM as RAM
making the situation worse when the exposure is also there via DAX in
the PMEM case. Volatile-RAM is arguably a safer use case since it's
possible to repair pages where the persistent case needs active
application coordination"
