The A80-uQ7 module uses UART4 as its external UART (i.e. as the one
UART exposed through the Qseven-compliant pinout). To enable early
debugging, we allow UART4 to be selected for earlyprintk.

The PRCM is a collection of clock controls, reset controls, and various
power switches/gates. Some of these can be independently listed and
supported, while a number of CPU related ones are used in tandem with
CPUCFG for SMP bringup and CPU hotplugging.

CPUCFG is a collection of registers that are mapped to the SoC's signals
from each individual processor core and associated peripherals, such as
resets for processors, L1/L2 cache and other things.
These registers are used for SMP bringup and CPU hotplugging.

The A80 stores some magic flags in a portion of the secure SRAM. The
BROM jumps directly to the software entry point set by the SMP code
if the flags are set. This is required for CPU0 hotplugging.

The A80 is a big.LITTLE SoC with 1 cluster of 4 Cortex-A7s and
1 cluster of 4 Cortex-A15s.
This patch adds support to bring up the second cluster and thus all
cores using the common MCPM code. Core/cluster power down has not
been implemented, thus CPU hotplugging and big.LITTLE switcher is
not supported.

Pull ARM SoC fixes from Arnd Bergmann:
"Here are a couple of bugfixes for v4.8-rc.
Most of them have actually been around for a while this time but for
some reason didn't get applied early on. The shmobile regulator fix
is the only one that isn't completely obvious.
Device tree changes:
- archtimer interrupts must be level triggered (multiple platforms)
- fix for USB and MMC clocks on STiH410
- fix split DT repository in case of raspberry-pi 3
- a new use of skeleton.dtsi on arm64 has crept in after that was
removed.
defconfig updates:
- xilinx vdma has a new Kconfig symbol name
- keystone requires CONFIG_NOP_USB_XCEIV since v4.8-rc1
Code fixes:
- fix regulator quirk on shmobile
- suspend-to-ram regression on EXYNOS

Pull ARM fixes from Russell King:
"Most of this update are fixes primarily discovered from testing on the
older StrongARM 1110 and PXA systems, as a result of recent interest
from several people in these platforms:
- Locomo interrupt handling incorrectly stores the handler data in
the chip's private data slot: when Locomo is combined with an
interrupt controller who's chip uses the chip private data, this
leads to an oops.
- SA1111 was missing a call to clk_disable() to clean up after a
failed probe.
- SA1111 and PCMCIA suspend/resume was broken:
The PCMCIA "ds" layer was using the legacy bus suspend/resume
methods, which the core PM code is no longer calling as a result of
device_pm_check_callbacks() introduced in commit aa8e54b559479
("PM / sleep: Go direct_complete if driver has no callbacks").
SA1111 was broken due to changes to PCMCIA which makes PCMCIA
suspend itself later than the SA1111 code expects, and resume
before the SA1111 code has initialised access to the pcmcia
sub-device.
- the default SA1111 interrupt mask polarity got messed up when it
was converted to use a dynamic interrupt base number for its
interrupts.
- fix platform_get_irq() error code propagation, which was causing
problems on platforms where the interrupt may not be available at
probe time in DT setups.
- fix the lack of clock to PCMCIA code on PXA platforms, which was
omitted in conversions of PXA to CCF.
- fix an oops in the PXA PCMCIA code caused by a previous commit not
realising that Lubbock is different from the rest of the PXA PCMCIA
drivers.
- ensure that SA1111 low-level PCMCIA drivers propagate their error
codes to the main probe function, rather than the driver silently
accepting a failure.
- fix the sa11xx debugfs reporting of timing information, which
always indicated zero due to the clock being a factor of 1000 out.
- fix the polarity of the status change signal reported from the
sockets.
Lastly, one ARM specific commit from Stefan Agner fixing the LPAE
cache attributes"

* tag 'for-linus-4.8b-rc6-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/xen/tip:
arm/xen: fix SMP guests boot
|
|
Commit 88e957d6e47f ("xen: introduce xen_vcpu_id mapping") broke SMP
ARM guests on Xen. When FIFO-based event channels are in use (this is
the default), evtchn_fifo_alloc_control_block() is called on
CPU_UP_PREPARE event and this happens before we set up xen_vcpu_id
mapping in xen_starting_cpu. Temporary fix the issue by setting direct
Linux CPU id <-> Xen vCPU id mapping for all possible CPUs at boot. We
don't currently support kexec/kdump on Xen/ARM so these ids always
match.
In future, we have several ways to solve the issue, e.g.:
- Eliminate all hypercalls from CPU_UP_PREPARE, do them from the
starting CPU. This can probably be done for both x86 and ARM and, if
done, will allow us to get Xen's idea of vCPU id from CPUID/MPIDR on
the starting CPU directly, no messing with ACPI/device tree
required.
- Save vCPU id information from ACPI/device tree on ARM and use it to
initialize xen_vcpu_id mapping. This is the same trick we currently
do on x86.

Add the required PCMCIA clock for the SA1111 "1800" device. This clock
is used to compute timing information for the PCMCIA interface in the
SoC device, rather than the SA1111. Hence, the provision of this clock
is a convenience for the driver and does not reflect the hardware, so
this must not be copied into DT.

The cachepolicy variable gets initialized using a masked pmd
value. So far, the pmd has been masked with flags valid for the
2-page table format, but the 3-page table format requires a
different mask. On LPAE, this lead to a wrong assumption of what
initial cache policy has been used. Later a check forces the
cache policy to writealloc and prints the following warning:
Forcing write-allocate cache policy for SMP
This patch introduces a new definition PMD_SECT_CACHE_MASK for
both page table formats which masks in all cache flags in both
cases.

SA1111 PCMCIA was broken when PCMCIA switched to using dev_pm_ops for
the PCMCIA socket class. PCMCIA used to handle suspend/resume via the
socket hosting device, which happened at normal device suspend/resume
time.
However, the referenced commit changed this: much of the resume now
happens much earlier, in the noirq resume handler of dev_pm_ops.
However, on SA1111, the PCMCIA device is not accessible as the SA1111
has not been resumed at _noirq time. It's slightly worse than that,
because the SA1111 has already been put to sleep at _noirq time, so
suspend doesn't work properly.
Fix this by converting the core SA1111 code to use dev_pm_ops as well,
and performing its own suspend/resume at noirq time.
This fixes these errors in the kernel log:
pcmcia_socket pcmcia_socket0: time out after reset
pcmcia_socket pcmcia_socket1: time out after reset
and the resulting lack of PCMCIA cards after a S2RAM cycle.

This file is included from DTS files under arch/arm64 too (via
broadcom/bcm2837-rpi-3-b.dts and broadcom/bcm2837.dtsi). There is a desire
not to have skeleton.dtsi for ARM64. See commit 3ebee5a2e141 ("arm64: dts:
kill skeleton.dtsi") for rationale for its removal.
As well as the addition of #*-cells also requires adding the device_type to
the rpi memory node explicitly.
Note that this change results in the removal of an empty /aliases node from
bcm2835-rpi-a.dtb and bcm2835-rpi-a-plus.dtb. I have no hardware to check
if this is a problem or not.
It also results in some reordering of the nodes in the DTBs (the /aliases
and /memory nodes come later). This isn't supposed to matter but, again,
I've no hardware to check if it is true in this particular case.

On arm/arm64, we depend on the kvm_unmap_hva* callbacks (via
mmu_notifiers::invalidate_*) to unmap the stage2 pagetables when
the userspace buffer gets unmapped. However, when the Hypervisor
process exits without explicit unmap of the guest buffers, the only
notifier we get is kvm_arch_flush_shadow_all() (via mmu_notifier::release
) which does nothing on arm. Later this causes us to access pages that
were already released [via exit_mmap() -> unmap_vmas()] when we actually
get to unmap the stage2 pagetable [via kvm_arch_destroy_vm() ->
kvm_free_stage2_pgd()]. This triggers crashes with CONFIG_DEBUG_PAGEALLOC,
which unmaps any free'd pages from the linear map.

The STiH4{07,10} platform contains some interconnect clocks which are used
by various IPs. If this clock isn't handled correctly by ST's EHCI/OHCI
drivers, their hub won't be found, the following error be shown and the
result will be non-working USB:

This reverts commit b5c86b7496d74f6e454bcab5166efa023e1f0459.
This is no longer needed due to other changes going into 4.8 to rename
the unit addresses on a large number of device nodes. So it was picked up
for v4.8-rc1 in error.

We're trying hard to detect when the HYP idmap overlaps with the
HYP va, as it makes the teardown of a cpu dangerous. But there is
one case where an overlap is completely safe, which is when the
whole of the kernel is idmap'ed, which is likely to happen on 32bit
when RAM is at 0x8000000 and we're using a 2G/2G VA split.
In that case, we can proceed safely.

Commit 833f2cbf7091 ("ARM: dts: imx6: change the core clock of spdif")
changed many more clocks than only the SPDIF core clock as stated in
the commit message.
The MLB clock has been added and this causes SPDIF regression as
reported by Xavi Drudis Ferran and also in this forum post:
https://forum.digikey.com/thread/34240
The MX6Q Reference Manual does not mention that MLB is a clock related
to SPDIF, so change it back to a dummy clock to restore SPDIF
functionality.
Thanks to Ambika for providing the fix at:

The current implementation only works if the da9xxx devices are added
before their drivers are registered. Only then it can apply the fixes to
both devices. Otherwise, the driver for the first device gets probed
before the fix for the second device can be applied. This is what
fails when using the IP core switcher or when having the i2c master
driver as a module.
So, we need to disable both da9xxx once we detected one of them. We now
use i2c_transfer with hardcoded i2c_messages and device addresses, so we
don't need the da9xxx client devices to be instantiated. Because the
fixup is used on specific boards only, the addresses are not going to
change.

The Exynos PMU node is an interrupt, clock and PMU (Power Management Unit)
controller, and these functionalities are supported by different drivers
that matches the same compatible strings.
Since commit 15cc2ed6dcf9 ("of/irq: Mark initialised interrupt controllers
as populated") the OF core flags interrupt controllers registered with the
IRQCHIP_DECLARE() macro as OF_POPULATED, so platform devices with the same
compatible string as the interrupt controller will not be registered.
This prevents the PMU platform device to be registered so the Exynos PMU
driver is never probed. This breaks (among other things) Suspend-to-RAM.
Fix this by clearing the OF_POPULATED flag in the PMU IRQ init callback,
to allow the Exynos PMU platform driver to be probed. The patch is based
on Philipp Zabel's "ARM: imx6: mark GPC node as not populated after irq
init to probe pm domain driver".

Commit b70661c70830 ("net: smc91x: use run-time configuration on all ARM
machines") broke some ARM platforms through several mistakes. Firstly,
the access size must correspond to the following rule:
(a) at least one of 16-bit or 8-bit access size must be supported
(b) 32-bit accesses are optional, and may be enabled in addition to
the above.
Secondly, it provides no emulation of 16-bit accesses, instead blindly
making 16-bit accesses even when the platform specifies that only 8-bit
is supported.
Reorganise smc91x.h so we can make use of the existing 16-bit access
emulation already provided - if 16-bit accesses are supported, use
16-bit accesses directly, otherwise if 8-bit accesses are supported,
use the provided 16-bit access emulation. If neither, BUG(). This
exactly reflects the driver behaviour prior to the commit being fixed.
Since the conversion incorrectly cut down the available access sizes on
several platforms, we also need to go through every platform and fix up
the overly-restrictive access size: Arnd assumed that if a platform can
perform 32-bit, 16-bit and 8-bit accesses, then only a 32-bit access
size needed to be specified - not so, all available access sizes must
be specified.
This likely fixes some performance regressions in doing this: if a
platform does not support 8-bit accesses, 8-bit accesses have been
emulated by performing a 16-bit read-modify-write access.
Tested on the Intel Assabet/Neponset platform, which supports only 8-bit
accesses, which was broken by the original commit.
