616d8cf0fa ARM: SoC fixes for 4.16
Here are are a couple of last-minute fixes for 4.16, mostly for
 regressions. As usual, the majory are device tree changes:
 
 - USB 3 support on rk3399 didn't work and is being reverted for now
 
 - One fix for an old suspend/resume bug on rk3399
 
 - A few regulator related fixes on Banana Pi M2, and on imx7d-sdb
 
 - A boot regression fix for all Aspeed SoCs failing to find
   their memory
 
 - One more dtc warning fix
 
 The other changes are:
 
 - A few updates to the MAINTAINERS file
 
 - A revert for an incorrect orion5x cleanup
 
 - Two power management fixes for OMAP

66f3731f39 Two fixes for omap variants for v4.16-rc cycle
Fix insecure W+X mapping warning for SRAM for omaps that
 don't yet use drivers/misc/*sram*.c code. An earlier attempt
 at fixing this turned out to cause problems with PM on omap3,
 this version works with PM on omap3.
 
 Also fix dmtimer probe for omap16xx devices that was noticed
 with the pending dmtimer move to drivers. It seems this has
 been broken for a while and is a non-critical for booting.
 It is needed for PM on omap16xx though.

73b9160d0d ARM: 8748/1: mm: Define vdso_start, vdso_end as array
Define vdso_start, vdso_end as array to avoid compile-time analysis error
for the case of built with CONFIG_FORTIFY_SOURCE.

and, since vdso_start, vdso_end are used in vdso.c only,
move extern-declaration from vdso.h to vdso.c.

If kernel is built with CONFIG_FORTIFY_SOURCE,
compile-time error happens at this code.
- if (memcmp(&vdso_start, "177ELF", 4))

The size of "&vdso_start" is recognized as 1 byte, but n is 4,
So that compile-time error is reported.

Commit 384b38b669 ("ARM: 7873/1: vfp: clear vfp_current_hw_state
for dying cpu") fixed the cpu dying notifier by clearing
vfp_current_hw_state[]. However commit e5b61bafe7 ("arm: Convert VFP
hotplug notifiers to state machine") incorrectly used the original
vfp_force_reload() function in the cpu dying notifier.

Fix it by going back to clearing vfp_current_hw_state[].

eb85a355c3 ARM: OMAP: Fix SRAM W+X mapping
We are still using custom SRAM code for some SoCs and are not marking
the PM code mapped to SRAM as read-only and executable after we're
done. With CONFIG_DEBUG_WX=y, we will get "Found insecure W+X mapping
at address" warning.

Let's fix this issue the same way as commit 728bbe75c8 ("misc: sram:
Introduce support code for protect-exec sram type") is doing for
drivers/misc/sram-exec.c.

On omap3, we need to restore SRAM when returning from off mode after
idle, so init time configuration is not enough.

And as we no longer have users for omap_sram_push_address() we can
make it static while at it.

Note that eventually we should be using sram-exec.c for all SoCs.

9bdc00a5c1 ARM: dts: aspeed: Add default memory node
When we removed the inclusion of skeleton.dtsi from the device trees, we
broke booting for systems with bootloaders that aren't device tre aware.
This can be seen, for example, when appending the device tree blob to
the kernel image.

The reason booting broke was that the kernel lacked the device_type
label in the memory node. Add in a default memory node wth the
device_type. It can contain the memory address as the location is fixed
for each SoC generation, but the size needs to be added by the
bootloader or the board specific dts.

dbe8a9dfd7 ARM: ux500: Fix PMU IRQ regression
Commit 2b05f6ae1e ("ARM: ux500: remove PMU IRQ bouncer")
deleted some code to bounce and work around the weird PMU
IRQs in the DB8500 ASIC, but did a semantic mistake:
since the auxdata was now unused, the call to
of_platform_populate() was removed, but this does not
work: the default platform population will only kick in
if .init_machine() is assigned NULL, and since the U8540
was still using the callback that was not the case.

Fix this by reinstating the call to of_platform_populate(),
but pass NULL as auxdata.

97ace515f0 ARM: SoC fixes for 4.16
This is the first set of bugfixes for ARM SoCs, fixing a couple
 of stability problems, mostly on TI OMAP and Rockchips platforms:
 
 - OMAP2 hwmod clocks must be enabled in the correct order
 
 - OMAP3 Wakeup from resume through PRM IRQ was unreliable
 
 - One regression on OMAP5 caused by a kexec fix
 
 - Rockchip ethernet needs some settings for stable operation on Rock64
 
 - Rockchip based Chrombook Plus needs another clock setting for
   stable display suspend/resume
 
 - Rockchip based phyCORE-RK3288 was able to run at an invalid
   CPU clock frequency
 
 - Rockchip MMC link was sometimes unreliable
 
 - Multiple fixes to avoid crashes in the Broadcom STB DPFE driver
 
 Other minor changes include:
 
 - Devicetree fixes for incorrect hardware description (rockchip,
   omap, Gemini, amlogic)
 
 - Some MAINTAINER file updates to correct email and git addresses
 
 - Some fixes addressing 'make W=1' dtc warnings (broadcom, amlogic,
   cavium, qualcomm, hisilicon, zx)
 
 - Fixes for LTO-compilation (orion, davinci, clps711x)
 
 - One fix for an incorrect Kconfig errata selection
 
 - A memory leak in the OMAP timer driver
 
 - A kernel data leak in OMAP1 debugfs files

Jon attempted to fix the amount of RAM on the BCM958625HR in commit
c53beb47f6 ("ARM: dts: NSP: Correct RAM amount for BCM958625HR board")
but it seems like we tripped over some poorly documented schematics.

The top-level page of the schematics says the board has 2GB, but when
you end-up scrolling to page 6, you see two chips of 4GBit (512MB) but
what the bootloader really initializes only 512MB, any attempt to use
more than that results in data aborts. Fix this again back to 512MB.

29d1d52b06 ARM: dts: Set D-Link DNS-313 SATA to muxmode 0
This stops the driver from trying to probe the ATA slave
interface. The vendor code enables the slave interface
but the driver in the vendor tree does not make use of
it.

Setting it to muxmode 0 disables the slave interface:
the hardware only has the master interface connected
to the one harddrive slot anyways.

Without this change booting takes excessive time, so it
is very annoying to end users.

It is not valid for orion5x to use mac_pton().

First of all, the orion5x buffer is not NULL terminated.  mac_pton()
has no business operating on non-NULL terminated buffers because
only the caller can know that this is valid and in what manner it
is ok to parse this NULL'less buffer.

Second of all, orion5x operates on an __iomem pointer, which cannot
be dereferenced using normal C pointer operations.  Accesses to
such areas much be performed with the proper iomem accessors.

77ee2e1bac ARM: BCM: dts: Remove leading 0x and 0s from bindings notation
Improve the DTS files by removing all the leading "0x" and zeros to fix the
following dtc warnings:

Warning (unit_address_format): Node /XXX unit name should not have leading "0x"

and

Warning (unit_address_format): Node /XXX unit name should not have leading 0s

Converted using the following command:

find . -type f \( -iname *.dts -o -iname *.dtsi \) -exec sed -i -e "s/@\([0-9a-fA-FxX\.;:#]+\)\s*{/@\L\1 {/g" -e "s/@0x\(.*\) {/@\1 {/g" -e "s/@0+\(.*\) {/@\1 {/g" {} +^C

For simplicity, two sed expressions were used to solve each warnings separately.

To make the regex expression more robust a few other issues were resolved,
namely setting unit-address to lower case, and adding a whitespace before the
the opening curly brace:

https://elinux.org/Device_Tree_Linux#Linux_conventions

This will solve as a side effect warning:

Warning (simple_bus_reg): Node /XXX@<UPPER> simple-bus unit address format error, expected "<lower>"

omap_timer omap_timer.1: omap_dm_timer_probe: pm_runtime_get_sync failed!
omap_timer: probe of omap_timer.1 failed with error -13
...

We are checking for OMAP_TIMER_NEEDS_RESET flag elsewhere so this is
safe to do.

8337d08350 ARM: orion: fix orion_ge00_switch_board_info initialization
A section type mismatch warning shows up when building with LTO,
since orion_ge00_mvmdio_bus_name was put in __initconst but not marked
const itself:

include/linux/of.h: In function 'spear_setup_of_timer':
arch/arm/mach-spear/time.c:207:34: error: 'timer_of_match' causes a section type conflict with 'orion_ge00_mvmdio_bus_name'
 static const struct of_device_id timer_of_match[] __initconst = {
                                  ^
arch/arm/plat-orion/common.c:475:32: note: 'orion_ge00_mvmdio_bus_name' was declared here
 static __initconst const char *orion_ge00_mvmdio_bus_name = "orion-mii";
                                ^

As pointed out by Andrew Lunn, it should in fact be 'const' but not
'__initconst' because the string is never copied but may be accessed
after the init sections are freed. To fix that, I get rid of the
extra symbol and rewrite the initialization in a simpler way that
assigns both the bus_id and modalias statically.

I spotted another theoretical bug in the same place, where d->netdev[i]
may be an out of bounds access, this can be fixed by moving the device
assignment into the loop.

e519eedb68 arm: zx: dts: Remove leading 0x and 0s from bindings notation
Improve the DTS files by removing all the leading "0x" and zeros to fix the
following dtc warnings:

Warning (unit_address_format): Node /XXX unit name should not have leading "0x"

and

Warning (unit_address_format): Node /XXX unit name should not have leading 0s

Converted using the following command:

find . -type f \( -iname *.dts -o -iname *.dtsi \) -exec sed -i -e "s/@\([0-9a-fA-FxX\.;:#]+\)\s*{/@\L\1 {/g" -e "s/@0x\(.*\) {/@\1 {/g" -e "s/@0+\(.*\) {/@\1 {/g" {} +^C

For simplicity, two sed expressions were used to solve each warnings separately.

To make the regex expression more robust a few other issues were resolved,
namely setting unit-address to lower case, and adding a whitespace before the
the opening curly brace:

https://elinux.org/Device_Tree_Linux#Linux_conventions

This will solve as a side effect warning:

Warning (simple_bus_reg): Node /XXX@<UPPER> simple-bus unit address format error, expected "<lower>"

Trying to boot an RK3328 box with an HS200-capable eMMC, I see said eMMC
fail to initialise as it can't run its tuning procedure, because the
sample clock is missing. Upon closer inspection, whilst the clock is
present in the DT, its name is subtly incorrect per the binding, so
__of_clk_get_by_name() never finds it. By inspection, the drive clock
suffers from a similar problem, so has never worked properly either.

This error has propagated across the 32-bit DTs too, so fix those up.

67870eb120 ARM: kvm: fix building with gcc-8
In banked-sr.c, we use a top-level '__asm__(".arch_extension virt")'
statement to allow compilation of a multi-CPU kernel for ARMv6
and older ARMv7-A that don't normally support access to the banked
registers.

This is considered to be a programming error by the gcc developers
and will no longer work in gcc-8, where we now get a build error:

/tmp/cc4Qy7GR.s:34: Error: Banked registers are not available with this architecture. -- `mrs r3,SP_usr'
/tmp/cc4Qy7GR.s:41: Error: Banked registers are not available with this architecture. -- `mrs r3,ELR_hyp'

/tmp/cc4Qy7GR.s:76: Error: Banked registers are not available with this architecture. -- `mrs r3,SP_abt'

Passign the '-march-armv7ve' flag to gcc works, and is ok here, because
we know the functions won't ever be called on pre-ARMv7VE machines.
Unfortunately, older compiler versions (4.8 and earlier) do not understand
that flag, so we still need to keep the asm around.

Backporting to stable kernels (4.6+) is needed to allow those to be built
with future compilers as well.

This patch fixes a bootproblem with the Bananapi M2 board. Since there
are some regulators missing we add them right now. Those values come
from the schematic, below you can find a small overview:

* reg_aldo1:  3,3V, powers the wifi
* reg_aldo2:  2,5V, powers the IO of the RTL8211E
* reg_aldo3:  3,3V, powers the audio

* reg_dldo1:  3,0V, powers the RTL8211E
* reg_dldo2:  2,8V, powers the analog part of the csi
* reg_dldo3:  3,3V, powers misc
* reg_eldo1:  1,8V, powers the csi
* reg_ldo_io1:1,8V, powers the gpio

* reg_dc5ldo: needs to be always on

This patch updates also the vmmc-supply properties on the mmc0 and mmc2
node to use the allready existent regulators.
We can now remove the sunxi-common-regulators.dtsi include since we
don't need it anymore.
