43d9af3f19 ARM: dts: at91rm9200: pullup rx on uart0
For consistency with all other serial pins, add this pullup. It also
prevents the signal from floating and so consuming a useless extra amount
of power in crowbarred state if nothing is connected to RX.

5e04822f7d ARM: dts: at91: fixes uart pinctrl, set pullup on rx, clear pullup on tx
Remove pullup on uart TX signals, they are push-pull outputs thus
pullups are pointless.

Add pullup on uart RX signals, they prevent the RX signals to be left
floating and so consuming a useless extra amount of power in crowbarred
state if nothing is connected to RX.

e8fd0adf10 ARM: dts: at91: at91sam9g25: fix mux-mask pinctrl property
There are only 19 PIOB pins having primary names PB0-PB18. Not all of them
have a 'C' function. So the pinctrl property mask ends up being the same as the
other SoC of the at91sam9x5 series.

9a06757dcc ARM: dts: at91: sama5d4: fix pinctrl compatible string
The compatible string is incorrect. Add atmel,sama5d3-pinctrl since
it's the appropriate compatible string. Remove the
atmel,at91rm9200-pinctrl compatible string, this fallback is
useless, there are too many changes.

cf438f51c6 ARM: dts: at91: nattis: use up-to-date mtd partitions
The nattis currently relies on the cmdline to correctly configure the
MTD partition table, and the one given in the device tree is simply
ignored. Which is fortunate, since the device tree partition table is
bonkers and does not match reality.

So, in order to avoid confusion, fix the device tree partition table
to match what is expected (i.e. what is normally provided on the cmdline).
In particular, the rootfs partition should be mtd6.

 build-time warnings for bad device tree files. This includes fixes for
 the majority of platforms, including nomadik, samsung, lpc32xx, STi,
 spear, mediatek, freescale, qcom, realview, keystone, omap, kirkwood,
 renesas, hisilicon, and broadcom.
 
 Files get rearranged on a few platforms, in particular the Marvell
 Armada 7K/8K device tree files are changed in preparation for future
 SoC support, based on more than two of the same chips in one package,
 and some boards get renamed for oxnas for consistency.
 
 Finally, many existing SoCs gain descriptions for additional on-chip

  We finally managed to get the dtc warnings under control, with no more
  build-time warnings for bad device tree files. This includes fixes for
  the majority of platforms, including nomadik, samsung, lpc32xx, STi,
  spear, mediatek, freescale, qcom, realview, keystone, omap, kirkwood,
  renesas, hisilicon, and broadcom.

  Files get rearranged on a few platforms, in particular the Marvell
  Armada 7K/8K device tree files are changed in preparation for future
  SoC support, based on more than two of the same chips in one package,
  and some boards get renamed for oxnas for consistency.

  Finally, many existing SoCs gain descriptions for additional on-chip
  devices that we can now support with kernel drivers:

Pull power management updates from Rafael Wysocki:
 "This includes some infrastructure changes in the PM core, mostly
  related to integration between runtime PM and system-wide suspend and
  hibernation, plus some driver changes depending on them and fixes for
  issues in that area which have become quite apparent recently.

  Also included are changes making more x86-based systems use the Low
  Power Sleep S0 _DSM interface by default, which turned out to be
  necessary to handle power button wakeups from suspend-to-idle on
  Surface Pro3.

  On the cpufreq front we have fixes and cleanups in the core, some new
  hardware support, driver updates and the removal of some unused code
  from the CPU cooling thermal driver.

  Apart from this, the Operating Performance Points (OPP) framework is
  prepared to be used with power domains in the future and there is a
  usual bunch of assorted fixes and cleanups.

  Specifics:

   - Define a PM driver flag allowing drivers to request that their
     devices be left in suspend after system-wide transitions to the
     working state if possible and add support for it to the PCI bus

For now, we need to rely on dts alias for n900 lcd and tvout order
 to prevent occasional blank lcd. And we need to reduce the shut down
 temperature for dra7 for non-cpu thermal cases.
 
 And looks like we're missing the n9 volume key mappings and there is
 active work going happening for n9 at least for postmarketos. So let's
 make sure the keys can be actually used as they are the only buttons
 on n9 in addition to the power key.

ff5fdafc9e ARM: 8745/1: get rid of __memzero()
The __memzero assembly code is almost identical to memset's except for
two orr instructions. The runtime performance of __memset(p, n) and
memset(p, 0, n) is accordingly almost identical.

However, the memset() macro used to guard against a zero length and to
call __memzero at compile time when the fill value is a constant zero
interferes with compiler optimizations.

Arnd found tha the test against a zero length brings up some new
warnings with gcc v8:

  https://gcc.gnu.org/bugzilla/show_bug.cgi?id=82103

And successively rremoving the test against a zero length and the call
to __memzero optimization produces the following kernel sizes for
defconfig with gcc 6:

    text     data     bss       dec       hex  filename
12248142  6278960  413588  18940690   1210312  vmlinux.orig
12244474  6278960  413588  18937022   120f4be  vmlinux.no_zero_test
12239160  6278960  413588  18931708   120dffc  vmlinux.no_memzero

So it is probably not worth keeping __memzero around given that the
compiler can do a better job at inlining trivial memset(p,0,n) on its
own. And the memset code already handles a zero length just fine.

The BPF verifier conflict was some minor contextual issue.

The TUN conflict was less trivial.  Cong Wang fixed a memory leak of
tfile->tx_array in 'net'.  This is an skb_array.  But meanwhile in
net-next tun changed tfile->tx_arry into tfile->tx_ring which is a
ptr_ring.

The clcd device is lacking an interrupt-parent property, which makes
the interrupt unusable and shows up as a warning with the latest

arch/arm/boot/dts/ste-nomadik-nhk15.dtb: Warning (interrupts_property): Missing interrupt-parent for /amba/clcd@10120000

I looked up the old board files and found that this interrupt has
the same irqchip as all the other on-chip device, it just needs one
extra line.

Other platforms' device-tree files start with a platform prefix, such as
sun7i-a20-*.dts or at91-*.dts.
This naming scheme turns out to be handy when using multi-platform build
systems such as OpenWrt.
Prepend oxnas files with their platform prefix to comply with the naming
scheme already used for most other platforms.

5c1037196b ARM: dts: s5pv210: add interrupt-parent for ohci
The ohci-hcd node has an interrupt number but no interrupt-parent,
leading to a warning with current dtc versions:

arch/arm/boot/dts/s5pv210-aquila.dtb: Warning (interrupts_property): Missing interrupt-parent for /soc/ohci@ec300000
arch/arm/boot/dts/s5pv210-goni.dtb: Warning (interrupts_property): Missing interrupt-parent for /soc/ohci@ec300000
arch/arm/boot/dts/s5pv210-smdkc110.dtb: Warning (interrupts_property): Missing interrupt-parent for /soc/ohci@ec300000
arch/arm/boot/dts/s5pv210-smdkv210.dtb: Warning (interrupts_property): Missing interrupt-parent for /soc/ohci@ec300000
arch/arm/boot/dts/s5pv210-torbreck.dtb: Warning (interrupts_property): Missing interrupt-parent for /soc/ohci@ec300000

As seen from the related exynos dts files, the ohci and ehci controllers
always share one interrupt number, and the number is the same here as
well, so setting the same interrupt-parent is the reasonable solution
here.

ca32e0c4bf ARM: lpc3250: fix uda1380 gpio numbers
dtc warns about obviously incorrect GPIO numbers for the audio codec

It looks like the nodes are written for a different binding that combines
the GPIO number into a single number rather than a bank/number pair.
I found the right numbers on stackexchange.com, so this patch fixes
the warning and has a reasonable chance of getting things to actually
work.

[arnd: marked Cc:stable since this warning shows up with the latest dtc
       by default, and is more likely to actually cause problems than the
       other patches from this series]

64c358b3bd ARM: dts: dra7: Reduce shut down temperature of non-cpu thermal zones
On dra7, as per TRM, the HW shutdown (TSHUT) temperature is hardcoded
to 123C and cannot be modified by SW. This means that when the temperature
reaches 123C HW asserts TSHUT output which signals a warm reset.
The reset is held until the temperature goes below the TSHUT low (105C).

While in SW, the thermal driver continuously monitors current temperature
and takes decisions based on whether it reached an alert or a critical point.
The intention of setting a SW critical point is to prevent force reset by HW
and instead do an orderly_poweroff(). But if the SW critical temperature is
greater than or equal to that of HW then it defeats the purpose. To address
this and let SW take action before HW does keep the SW critical temperature
less than HW TSHUT value.

The value for SW critical temperature was chosen as 120C just to ensure
we give SW sometime before HW catches up.

cbe92b02b6 ARM: dts: n900: Add aliases for lcd and tvout displays
When both lcd and tv are enabled, the order in which they will be probed is
unknown, so it might happen (and it happens in reality) that tv is
configured as display0 and lcd as display1, which results in nothing
displayed on lcd, as display1 is disabled by default.

Fix that by providing correct aliases for lcd and tv

e14d7e5320 ARM: dts: Update ti-sysc data for existing users
Let's update the existing users with features and clock data as
specified in the binding. This is currently the smartreflex for most
part, and also few omap4 modules with no child device driver like
mcasp, abe iss and gfx.

Note that we had few mistakes that did not get noticed as we're still
probing the SmartReflex driver with legacy platform data and using
"ti,hwmods" legacy property for ti-sysc driver.

So let's fix the omap4 and dra7 smartreflex registers as there is no
no revision register.

And on omap4, the mcasp module has a revision register according to
the TRM.

And for omap34xx we need a different configuration compared to 36xx.
And the smartreflex on 3517 we've always kept disabled so let's
remove any references to it.
