git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/soc
These changes contain the OMAP USB related platform data changes
that were dropped from linux next because of the merge conflicts
as requested by me and Olof. The reason was that at this point
we really should be able to do the arch/arm related changes
separately from driver changes to avoid dependencies between
branches.
These patches were initially part of the USB related MFD patches.
Based on our comments, Roger Quadros quickly reworked these
patches into a shared branch between ARM SoC tree and the MFD
tree, then separate patches for the OMAP platform data and
MFD driver.
Note that this branch will conflict with c1d1cd597fc7
("ARM: OMAP2+: omap_device: remove obsolete pm_lats and
early_device code"). Please see http://lkml.org/lkml/2013/2/11/16
for the merge resolution.

This resolves a panic-on-boot regression introduced by me when incorrectly
updating TMU clock definitions.

ARM: shmobile: r8a7779: Correct TMU clock support again
Signed-off-by: Arnd Bergmann <arnd@arndb.de>

After discussion on the linux-sh mailing list and reference to the
hardware documentation it appears that 'TMU00', 'TMU01' and 'TMU02'
use a common clock.
The sh_tmu.1 portion of this change resolves a regression introduced in
58079fa7d54a0929d304054ee759187a2ccd3cdf (ARM: shmobile: r8a7779: Correct
TMU clock support) and fixes a regression introduced by that patch. That
patch is queued up for v3.9.

The code in arch/arm/mach-prima2/headsmp.S is used for
both boot time initialization and for cpu hotplug,
so it must not be discarded after the initial boot
is complete. This replaces the __INIT annotation
with __CPUINIT, and marks the sirfsoc_cpu_die as
__ref to annotate that it correctly uses the sections.
Without this patch, building prima2_defconfig results in:
WARNING: arch/arm/mach-prima2/built-in.o(.cpuinit.text+0x130): Section mismatch in reference from the function sirfsoc_boot_secondary() to the function .init.text:sirfsoc_secondary_startup()
The function __cpuinit sirfsoc_boot_secondary() references
a function __init sirfsoc_secondary_startup().
If sirfsoc_secondary_startup is only used by sirfsoc_boot_secondary then
annotate sirfsoc_secondary_startup with a matching annotation.

Let's have a single platform data structure for the OMAP's High-Speed
USB host subsystem instead of having 3 separate ones i.e. one for
board data, one for USB Host (UHH) module and one for USB-TLL module.
This makes the code much simpler and avoids creating multiple copies of
platform data.

From Dinh Nguyen, this is a series of patches introducing support for
socfpga hardware (Altera Cyclone5). It also includes a cleanup that
moves some of the ARMv7 cache maintenance functions to a common location,
since three other platforms aready implemented it separately.

arm: socfpga: Add SMP support for actual socfpga harware
arm: Add v7_invalidate_l1 to cache-v7.S

CONFIG_ARCH_TEGRA_114_SOC doesn't currently enable gpiolib, which causes
numerous build problems building a Tegra kernel with only Tegra114
enabled, and not Tegra20 or Tegra30. Enable ARCH_REQUIRE_GPIOLIB to
solve this. However, all Tegra will use gpiolib, so select this option
from ARCH_TEGRA rather than each individual ARCH_TEGRA_*_SOC, to
prevent this problem for any future chips.

This patch fixes the build error when ARCH_TEGRA_114_SOC is enabled
and ARCH_TEGRA_3x_SOC is disabled.
This provides Tegra114 with its own tegra114_init_early() instead of
making use of tegra30_init_early() so that T114 build doesn't depend
on T3x anymore.

Pull ARM fixes from Russell King:
"I was going to hold these off until v3.8 was out, and send them with a
stable tag, but as everyone else is pushing much bigger fixes which
Linus is accepting, let's save people from the hastle of having to
patch v3.8 back into working or use a stable kernel.
Looking at the diffstat, this really is high value for its size; this
is miniscule compared to how the -rc6 to tip diffstat currently looks.
So, four patches in this set:
- Punit Agrawal reports that the kernel no longer boots on MPCore due
to a new assumption made in the GIC code which isn't true of
earlier GIC designs. This is the biggest change in this set.
- Punit's boot log also revealed a bunch of WARN_ON() dumps caused by
the DT-ification of the GIC support without fixing up non-DT
Realview - which now sees a greater number of interrupts than it
did before.
- A fix for the DMA coherent code from Marek which uses the wrong
check for atomic allocations; this can result in spinlock lockups
or other nasty effects.
- A fix from Will, which will affect all Android based platforms if
not applied (which use the 2G:2G VM split) - this causes
particularly 'make' to misbehave unless this bug is fixed."
* 'fixes' of git://git.linaro.org/people/rmk/linux-arm:
ARM: 7641/1: memory: fix broken mmap by ensuring TASK_UNMAPPED_BASE is aligned
ARM: DMA mapping: fix bad atomic test
ARM: realview: ensure that we have sufficient IRQs available
ARM: GIC: fix GIC cpumask initialization
|
|
We have received multiple reports of mmap failures when running with a
2:2 vm split. These manifest as either -EINVAL with a non page-aligned
address (ending 0xaaa) or a SEGV, depending on the application. The
issue is commonly observed in children of make, which appears to use
bottom-up mmap (assumedly because it changes the stack rlimit).
Further investigation reveals that this regression was triggered by
394ef6403abc ("mm: use vm_unmapped_area() on arm architecture"), whereby
TASK_UNMAPPED_BASE is no longer page-aligned for bottom-up mmap, causing
get_unmapped_area to choke on misaligned addressed.
This patch fixes the problem by defining TASK_UNMAPPED_BASE in terms of
TASK_SIZE and explicitly aligns the result to 16M, matching the other
end of the heap.

This happens because the DMA allocation code is not respecting atomic
allocations correctly.
GFP flags should not be tested for GFP_ATOMIC to determine if an
atomic allocation is being requested. GFP_ATOMIC is not a flag but
a value. The GFP bitmask flags are all prefixed with __GFP_.
The rest of the kernel tests for __GFP_WAIT not being set to indicate
an atomic allocation. We need to do the same.

Some early GIC implementations return zero for the first distributor
CPU routing register. This means we can't rely on that telling us
which CPU interface we're connected to. We know that these platforms
implement PPIs for IRQs 29-31 - but we shouldn't assume that these
will always be populated.
So, instead, scan for a non-zero CPU routing register in the first
32 IRQs and use that as our CPU mask.

ARM: tegra: add Tegra114 SoC support
This pull request adds initial support for the Tegra114 SoC, which
integrates a quad-core ARM Cortex-A15 CPU. I'm proud to observe that we
posted the initial versions of these patches before the final official
announcement of this chip.
These patches are enough to boot with a UART-based console, support the
Dalmore and Pluto reference/evaluation boards, instantiate the GPIO and
pinctrl drivers, and enable a cpuidle state. As yet, no clocks or
storage devices are supported, but patches for those will follow shortly.
This pull request is based on (most of) the previous pull request with
tag tegra-for-3.9-soc-cpuidle, followed by a merge of the previous pull
request with tag tegra-for-3.9-scu-base-rework.

From Stephen Warren:
ARM: tegra: USB driver cleanup
The Tegra USB driver has a number of issues:
1) The PHY driver isn't a true platform device, and doesn't implement
the standard USB PHY API.
2) struct device instance numbers were used to make decisions in the
driver, rather than being parameterized by DT or platform data.
This pull request solves issue (2), and lays the groundwork for solving
issue (1). The work on issue (1) involved introducing new DT nodes for
the USB PHYs, which in turn interacted with the Tegra common clock
framework changes, due to the move of clock lookups into device tree.
Hence, these USB driver changes are taken through the Tegra tree with
acks from USB maintainers.
This pull request is based on the previous pull request, with tag
tegra-for-3.9-soc-ccf.

From Stephen Warren:
ARM: tegra: Common Clock Framework rework
Tegra already supports the common clock framework, but had issues:
1) The clock driver was located in arch/arm/mach-tegra/ rather than
drivers/clk/.
2) A single "Tegra clock" type was implemented, rather than separate
clock types for PLL, mux, divider, ... type in HW.
3) Clock lookups by device drivers were still driven by device name
and connection ID, rather than through device tree.
This pull request solves all three issues. This required some DT changes
to add clocks properties, and driver changes to request clocks more
"correctly". Finally, this rework allows all AUXDATA to be removed from
Tegra board files, and various duplicate clock lookup entries to be
removed from the driver.
This pull request is based on the previous pull request, with tag
tegra-for-3.9-cleanup.

Extend imx6q DEBUG_LL uart port selection support to cover all i.MX
SoCs. The 'range' of the Kconfig option gets dropped, as users
looking at the option must know the uart number on his board. The
bottom line is that the build system will report an error if an
invalid port number is picked for given SoC.
The header arch/arm/include/debug/imx-uart.h is created to accommodate
all the uart base addresses. And the header will also be used for
other low-level debug facility later.

It's improper to use combined symbol DEBUG_IMX31_IMX35_UART for
