Pull ARM fixes from Russell King:
"Three fixes this time around:
- Two fixes for noMMU, fixing the decompressor header layout, and
preventing a build error with some configurations.
- Fixing the hyp-stub updates that went in during the merge window
for platforms that use MCPM"

ARM: 8675/1: MCPM: ensure not to enter __hyp_soft_restart from loopback and cpu_power_down
|
|
As reported by Patrice, the header layout of the decompressor is
incorrect when building for v7-M. In this case, the __nop macro
resolves to 'mov r0, r0', which is emitted as a narrow encoding,
resulting in the header data fields to end up at lower offsets than
required.
Given the variety of targets we need to support with the same code,
the startup sequence is a bit of a jumble, and uses instructions
and macros whose encoding widths cannot be specified (badr), or only
exist in a narrow encoding (bx)
So force the use of a wide encoding in __nop, and replace the start
sequence with a simple jump to the label marking the start of code,
preceded by a Thumb2 mode switch if required (using explicit wide
encodings where appropriate). The label itself can be moved to the
start of code [where it belongs] due to the larger range of branch
instructions as compared to adr instructions.

arch_teardown_dma_ops() being the inverse of arch_setup_dma_ops()
,dma_ops should be cleared in the teardown path. Currently, only the
device's iommu mapping structures are cleared in arch_teardown_dma_ops,
but not the dma_ops. So on the next reprobe, dma_ops left in place is
stale from the first IOMMU setup, but iommu mappings has been disposed
of. This is a problem when the probe of the device is deferred and
recalled with the IOMMU probe deferral.
So for fixing this, slightly refactor by moving the code from
__arm_iommu_detach_device to arm_iommu_detach_device and cleanup
the former. This takes care of resetting the dma_ops in the teardown
path.

arch_setup_dma_ops() is used in device probe code paths to create an
IOMMU mapping and attach it to the device. The function assumes that the
device is attached to a device-specific IOMMU instance (or at least a
device-specific TLB in a shared IOMMU instance) and thus creates a
separate mapping for every device.
On several systems (Renesas R-Car Gen2 being one of them), that
assumption is not true, and IOMMU mappings must be shared between
multiple devices. In those cases the IOMMU driver knows better than the
generic ARM dma-mapping layer and attaches mapping to devices manually
with arm_iommu_attach_device(), which sets the DMA ops for the device.
The arch_setup_dma_ops() function takes this into account and bails out
immediately if the device already has DMA ops assigned. However, the
corresponding arch_teardown_dma_ops() function, called from driver
unbind code paths (including probe deferral), will tear the mapping down
regardless of who created it. When the device is reprobed
arch_setup_dma_ops() will be called again but won't perform any
operation as the DMA ops will still be set.
We need to reset the DMA ops in arch_teardown_dma_ops() to fix this.
However, we can't do so unconditionally, as then a new mapping would be
created by arch_setup_dma_ops() when the device is reprobed, regardless
of whether the device needs to share a mapping or not. We must thus keep
track of whether arch_setup_dma_ops() created the mapping, and only in
that case tear it down in arch_teardown_dma_ops().
Keep track of that information in the dev_archdata structure. As the
structure is embedded in all instances of struct device let's not grow
it, but turn the existing dma_coherent bool field into a bitfield that
can be used for other purposes.

Ethernet networking on K2L has been broken since v4.11-rc1. This was
caused by commit 32a34441a9bd ("ARM: keystone: dts: fix netcp clocks
and add names"). This commit inadvertently moves on-chip static RAM
clock to the end of list of clocks provided for netcp. Since keystone
PM domain support does not have a list of recognized con_ids, only the
first clock in the list comes under runtime PM management. This means
the OSR (On-chip Static RAM) clock remains disabled and that broke
networking on K2L.
The OSR is used by QMSS on K2L as an external linking RAM. However this
is a standalone RAM that can be used for non-QMSS usage (as well as from
DSP side). So add a SRAM device node for the same and add the OSR clock
to the node.
Remove the now redundant OSR clock node from netcp.
To manage all clocks defined for netCP's use by runtime PM needs keystone
generic power domain (genpd) driver support which is under works.
Meanwhile, this patch restores K2L networking and is correct irrespective
of any future genpd work since OSR is an independent module and not part
of NetCP anyway.

cpu_power_down
Commit 9da5ac236de6 ("ARM: soft-reboot into same mode that we entered
the kernel") added support to enter the new kernel in the same processor
mode as the previous one when we soft-reboot from one kernel into
another by pass a flag to cpu_reset() so it knows what to do exactly.
However it missed to make similar changes in MCPM code. Due to the
missing flag, the CPUs enter HYP mode which is not supported with MCPM.
MCPM works only in secure mode as it manages CCI.
This patch aligns the cpu_reset call in MCPM with other changes in the
above mentioned commit by making phys_reset_t to follow the prototype
of cpu_reset().

It makes sense to have a stripped-down defconfig for just Gemini, as
it is a pretty small platform used in NAS etc, and will use appended
device tree. It is also quick to compile and test. Hopefully this
defconfig can be a good base for distributions such as OpenWRT.
I plan to add in the config options needed for the different
variants of Gemini as we go along.

We use a directory under arch/$ARCH/boot/dts as an include path
that has links outside of the subtree to find dt-bindings from under
include/dt-bindings. That's been working well, but new DT architectures
haven't been adding them by default.
Recently there's been a desire to share some of the DT material between
arm and arm64, which originally caused developers to create symlinks or
relative includes between the subtrees. This isn't ideal -- it breaks
if the DT files aren't stored in the exact same hierarchy as the kernel
tree, and generally it's just icky.
As a somewhat cleaner solution we decided to add a $ARCH/ prefix link
once, and allow DTS files to reference dtsi (and dts) files in other
architectures that way.
Original approach was to create these links under each architecture,
but it lead to the problem of recursive symlinks.
As a remedy, move the include link directories out of the architecture

On dra7, as per TRM, the HW shutdown (TSHUT) temperature is hardcoded
to 123C and cannot be modified by SW. This means when the temperature
reaches 123C HW asserts TSHUT output which signals a warm reset.
This 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.

'davinci_pm_init'
It is wrong to iounmap resources in the normal path of davinci_pm_init()
The 3 ioremap'ed fields of 'pm_config' can be accessed later on in other

The Raspberry Pi startup stub files for multi-core BCM283X processors
make the secondary CPUs spin until the corresponding mailbox is
written. These stubs are loaded at physical address 0x00000xxx (as seen
by the ARMs), but this page will be reused by the kernel unless it is
explicitly reserved, causing the waiting cores to execute random code.
Use the /memreserve/ Device Tree directive to mark the first page as
off-limits to the kernel.

Hardware debugging in guests is not intercepted currently, it means
that a malicious guest can bring down the entire machine by writing
to the debug registers.
This patch enable trapping of all debug registers, preventing the
guests to access the debug registers. This includes access to the
debug mode(DBGDSCR) in the guest world all the time which could
otherwise mess with the host state. Reads return 0 and writes are
ignored (RAZ_WI).
The result is the guest cannot detect any working hardware based debug
support. As debug exceptions are still routed to the guest normal
debug using software based breakpoints still works.
To support debugging using hardware registers we need to implement a
debug register aware world switch as well as special trapping for
registers that may affect the host state.

The board file for imx6sx-sdb overrides cpufreq operating points to use
higher voltages. This is done because the board has a shared rail for
VDD_ARM_IN and VDD_SOC_IN and when using LDO bypass the shared voltage
needs to be a value suitable for both ARM and SOC.
This only applies to LDO bypass mode, a feature not present in upstream.
When LDOs are enabled the effect is to use higher voltages than necessary
for no good reason.
Setting these higher voltages can make some boards fail to boot with ugly
semi-random crashes reminiscent of memory corruption. These failures only
happen on board rev. C, rev. B is reported to still work.

[ 36.596900] mc13xxx 0-0008: Failed to read IRQ status: -6
Also when reading the interrupts via 'cat /proc/interrupts' the
PMIC GPIO interrupt counter does not stop increasing.
The reason for the storm of interrupts is that the PUS field of
register IOMUXC_SW_PAD_CTL_PAD_CSI0_DAT5 is currently configured as:
10 : 100k pullup
and the PMIC interrupt is being registered as IRQ_TYPE_LEVEL_HIGH type,
which is the correct type as per the MC34708 datasheet.
Use the default power on value for the IOMUX, which sets PUS field as:
00: 360k pull down
This prevents the spurious PMIC interrupts from happening.
Commit e1ffceb078c6 ("ARM: imx53: qsrb: fix PMIC interrupt level")
correctly described the irq type as IRQ_TYPE_LEVEL_HIGH, but
missed to update the IOMUX of the PMIC GPIO as pull down.
