Linus Torvalds 63cbb3b364 ARM: SoC fixes
A slightly larger set of fixes have accrued in the last two weeks.
 Mostly a collection of the usual smaller fixes:
 
  - Marvell Armada: USB phy setup issues on Turris Mox
 
  - Broadcom: GPIO/pinmux DT mapping corrections for Stingray, MMC bus
  width fix for RPi Zero W, GPIO LED removal for RPI CM3. Also some
  maintainer updates.
 
  - OMAP: Fixlets for display config, interrupt settings for wifi, some
    clock/PM pieces. Also IOMMU regression fix and a ti-sysc no-watchdog
    regression fix.
 
  - i.MX: A few fixes around PM/settings, some devicetree fixlets and
  catching up with config option changes in DRM
 
  - Rockchip: RockRro64 misc DT fixups, Hugsun X99 USB-C, Kevin display
  panel settings
 
 ... and some smaller fixes for Davinci (backlight, McBSP DMA), Allwinner
 (phy regulators, PMU removal on A64, etc).

Olof Johansson f82bc13540 Three fixes for omaps for v5.4-rc cycle
Two regression fixes for omap3 iommu. I missed applying two omap3
 related iommu pdata quirks patches earlier because the kbuild test
 robot produced errors on them for missing dependencies.
 
 Fix ti-sysc interconnect target module driver handling for watchdog
 quirk. I must have tested this earlier only with watchdog service
 running, but clearly it does not do what it needs to do.

   as we moved to use generic LCD panels
 
 - Remove unused twl_keypad for logicpd-torpedo-som to avoid boot
   time warnings. This is only a cosmetic fix, but at least dmesg output
   is now getting more readable after all the fixes to remove pointless
   warnings
 
 - Fix gpu_cm node name as we still have a non-standard node name
   dependency for clocks. This should eventually get fixed by use
   of domain specific compatible property
 
 - Fix use of i2c-mux-idle-disconnect for m3874-iceboard

afzal mohammed 2ecb287998 ARM: 8926/1: v7m: remove register save to stack before svc
r0-r3 & r12 registers are saved & restored, before & after svc
respectively. Intention was to preserve those registers across thread to
handler mode switch.

On v7-M, hardware saves the register context upon exception in AAPCS
complaint way. Restoring r0-r3 & r12 is done from stack location where
hardware saves it, not from the location on stack where these registers
were saved.

To clarify, on stm32f429 discovery board:

1. before svc, sp - 0x90009ff8
2. r0-r3,r12 saved to 0x90009ff8 - 0x9000a00b
3. upon svc, h/w decrements sp by 32 & pushes registers onto stack
4. after svc,  sp - 0x90009fd8
5. r0-r3,r12 restored from 0x90009fd8 - 0x90009feb

Above means r0-r3,r12 is not restored from the location where they are
saved, but since hardware pushes the registers onto stack, the registers
are restored correctly.

Note that during register saving to stack (step 2), it goes past
0x9000a000. And it seems, based on objdump, there are global symbols
residing there, and it perhaps can cause issues on a non-XIP Kernel
(on XIP, data section is setup later).

Based on the analysis above, manually saving registers onto stack is at
best no-op and at worst can cause data section corruption. Hence remove
storing of registers onto stack before svc.

bcm2835-rpi.dtsi defines the behavior of the ACT LED, which is available

GPIO on CM3 in mainline yet, so this node was left incomplete without
the actual GPIO definition. Since commit 025bf37725 ("gpio: Fix return

issues of the leds-gpio driver for users of the CM3 dtsi file.

Masahiro Yamada 851140ab0d ARM: 8908/1: add __always_inline to functions called from __get_user_check()
KernelCI reports that bcm2835_defconfig is no longer booting since
commit ac7c3e4ff4 ("compiler: enable CONFIG_OPTIMIZE_INLINING
forcibly") (https://lkml.org/lkml/2019/9/26/825).

I also received a regression report from Nicolas Saenz Julienne
(https://lkml.org/lkml/2019/9/27/263).

This problem has cropped up on bcm2835_defconfig because it enables
CONFIG_CC_OPTIMIZE_FOR_SIZE. The compiler tends to prefer not inlining
functions with -Os. I was able to reproduce it with other boards and
defconfig files by manually enabling CONFIG_CC_OPTIMIZE_FOR_SIZE.

The __get_user_check() specifically uses r0, r1, r2 registers.
So, uaccess_save_and_enable() and uaccess_restore() must be inlined.
Otherwise, those register assignments would be entirely dropped,
according to my analysis of the disassembly.

Prior to commit 9012d01166 ("compiler: allow all arches to enable
CONFIG_OPTIMIZE_INLINING"), the 'inline' marker was always enough for
inlining functions, except on x86.

Since that commit, all architectures can enable CONFIG_OPTIMIZE_INLINING.
So, __always_inline is now the only guaranteed way of forcible inlining.

I added __always_inline to 4 functions in the call-graph from the
__get_user_check() macro.

Tony Lindgren 087a2b7ec9 ARM: dts: Use level interrupt for omap4 & 5 wlcore
Commit 572cf7d7b0 ("ARM: dts: Improve omap l4per idling with wlcore edge
sensitive interrupt") changed wlcore interrupts to use edge interrupt based
on what's specified in the wl1835mod.pdf data sheet.

However, there are still cases where we can have lost interrupts as
described in omap_gpio_unidle(). And using a level interrupt instead of edge
interrupt helps as we avoid the check for untriggered GPIO interrupts in
omap_gpio_unidle().

And with commit e6818d29ea ("gpio: gpio-omap: configure edge detection
for level IRQs for idle wakeup") GPIOs idle just fine with level interrupts.

Let's change omap4 and 5 wlcore users back to using level interrupt
instead of edge interrupt. Let's not change the others as I've only seen
this on omap4 and 5, probably because the other SoCs don't have l4per idle
independent of the CPUs.

The clkctrl code searches for the parent clockdomain based on the name
of the CM provider node. The introduction of SGX node for omap5 made
the node name for the gpu_cm to be clock-controller. There is no
clockdomain named like this, so the lookup fails. Fix by changing

   is needed
 
 - Recent ti-sysc interconnect target module changes need the gpio
   module disabled on some boards, but this now needs to happen at
   the module level, not at the gpio driver level
 
 - Recent changes to probe system timers with ti-sysc caused warnings
   about mismatch in syconfig registers, so let's configure the option
   for RESET_STATUS as available in the TRMs
 
 - Recent changes to probe LCDC with ti-sysc caused warnings about

   idlemodes for both platform data and dts as documented in TRMs
 
 - Since we moved mach-omap2 to probe with device tree, we've been

Ard Biesheuvel 3aa6d4abd4 crypto: arm/aes-ce - build for v8 architecture explicitly
The NEON/Crypto Extensions based AES implementation for 32-bit ARM
can be built in a kernel that targets ARMv6 CPUs and higher, even
though the actual code will not be able to run on that generation,
but it allows for a portable image to be generated that can will
use the special instructions only when they are available.

Since those instructions are part of a FPU profile rather than a
CPU profile, we don't override the architecture in the assembler
code, and most of the scalar code is simple enough to be ARMv6
compatible. However, that changes with commit c61b1607ed,
which introduces calls to the movw/movt instructions, which are
v7+ only.

So override the architecture in the .S file to armv8-a, which
matches the architecture specification in the crypto-neon-fp-armv8
FPU specificier that we already using. Note that using armv7-a
here may trigger an issue with the upcoming Clang 10 release,
which no longer permits .arch/.fpu combinations it views as
incompatible.
