d0ac5d8e67 ARM: SoC fixes
We've been sitting on our fixes branch for a while, so this batch is
 unfortunately on the large side.
 
 A lot of these are tweaks and fixes to device trees, fixing various bugs
 around clocks, reg ranges, etc. There's also a few defconfig updates
 (which are on the late side, no more of those).
 
 All in all the diffstat is bigger than ideal at this time, but the nothing
 in here seems particularly risky.

Renesas ARM Based SoC Fixes for v3.19

This pull request is based on the last round of SoC updates for v3.19,
Fourth Round of Renesas ARM Based SoC Updates for v3.19, tagged as
renesas-soc3-for-v3.19, merged into your next/soc branch and included in
v3.19-rc1.

- ARM: shmobile: r8a7740: Instantiate GIC from C board code in legacy builds

  Set .control_parent for all irqpin instances for sh73a0 SoC when booting
  using legacy C.

- ARM: shmobile: r8a7740: Instantiate GIC from C board code in legacy builds

  This fixes a long standing problem which has been present since
  the sh73a0 SoC started using the INTC External IRQ pin driver.

  The patch that introduced the problem is 341eb5465f ("ARM:
  shmobile: INTC External IRQ pin driver on sh73a0") which was included
  in v3.10.

25217fef35 ARM: dts: disable CCI on exynos5420 based arndale-octa
The arndale-octa board was giving "imprecise external aborts" during
boot-up with MCPM enabled. CCI enablement of the boot cluster was found
to be the cause of these aborts (possibly because the secure f/w was not
allowing it). Hence, disable CCI for the arndale-octa board.

c9b75d51c9 ARM: rockchip: disable jtag/sdmmc autoswitching on rk3288
rk3288 SoCs have a function to automatically switch between jtag/sdmmc pinmux
settings depending on the card state. This collides with a lot of assumptions.

It only works when using the internal card-detect mechanism and breaks
horribly when using either the normal card-detect via the slot-gpio function
or via any other pin. Also there is of course no link between the mmc and jtag
on the software-side, so the jtag clocks may very well be disabled when the
card is ejected and the soc switches back to the jtag pinmux.

Leaving the switching function enabled did result in mmc timeouts and rcu
stalls thus hanging the system on 3.19-rc1. Therefore disable it in all cases,
as we expect the devicetree to explicitly select either mmc or jtag pinmuxes
anyway.

3d125f9c91 net: fec: fix MDIO bus assignement for dual fec SoC's
On i.MX28, the MDIO bus is shared between the two FEC instances.
The driver makes sure that the second FEC uses the MDIO bus of the
first FEC. This is done conditionally if FEC_QUIRK_ENET_MAC is set.
However, in newer designs, such as Vybrid or i.MX6SX, each FEC MAC
has its own MDIO bus. Simply removing the quirk FEC_QUIRK_ENET_MAC
is not an option since other logic, triggered by this quirk, is
still needed.

Furthermore, there are board designs which use the same MDIO bus
for both PHY's even though the second bus would be available on the
SoC side. Such layout are popular since it saves pins on SoC side.
Due to the above quirk, those boards currently do work fine. The
boards in the mainline tree with such a layout are:
- Freescale Vybrid Tower with TWR-SER2 (vf610-twr.dts)
- Freescale i.MX6 SoloX SDB Board (imx6sx-sdb.dts)

This patch adds a new quirk FEC_QUIRK_SINGLE_MDIO for i.MX28, which
makes sure that the MDIO bus of the first FEC is used in any case.

However, the boards above do have a SoC with a MDIO bus for each FEC
instance. But the PHY's are not connected in a 1:1 configuration. A
proper device tree description is needed to allow the driver to
figure out where to find its PHY. This patch fixes that shortcoming
by adding a MDIO bus child node to the first FEC instance, along
with the two PHY's on that bus, and making use of the phy-handle
property to add a reference to the PHY's.

Appearance: On some SAMA5D4EK boards, after power up, the Eth1 doesn't work.

Reason: The PIOE2 pin is connected to the NAND_Tree# of KSZ8081,
But it outputs LOW during the reset period, which cause the NAND_Tree# enabled.

Add phy_fixup() to disable NAND_Tree by overriding the Operation

in many contexts, so x86_64 should not use it without extra care
from interrupt context, let alone NMI context.

This will allow x86_64 to override the logic and will supply some
scratch space to use to make a cleaner copy of user regs.

b0ddb319db ARM: shmobile: sh73a0 legacy: Set .control_parent for all irqpin instances
The sh73a0 INTC can't mask interrupts properly most likely due to a
hardware bug. Set the .control_parent flag to delegate masking to the
parent interrupt controller, like was already done for irqpin1.

Without this, accessing the three-axis digital accelerometer ADXL345
on kzm9g through /dev/input/event1 causes an interrupt storm, which
requires a power-cycle to recover from.

This was inspired by a patch for arch/arm/boot/dts/sh73a0.dtsi from

ac08468867 ARM: 8253/1: mm: use phys_addr_t type in map_lowmem() for kernel mem region
Now local variables kernel_x_start and kernel_x_end defined using
'unsigned long' type which is wrong because they represent physical
memory range and will be calculated wrongly if LPAE is enabled.
As result, all following code in map_lowmem() will not work correctly.

For example, Keystone 2 boot is broken because
 kernel_x_start == 0x0000 0000
 kernel_x_end   == 0x0080 0000

instead of
 kernel_x_start == 0x0000 0008 0000 0000
 kernel_x_end   == 0x0000 0008 0080 0000
and as result whole low memory will be mapped with MT_MEMORY_RW
permissions by code (start > kernel_x_end):
		} else if (start >= kernel_x_end) {
			map.pfn = __phys_to_pfn(start);
			map.virtual = __phys_to_virt(start);
			map.length = end - start;
			map.type = MT_MEMORY_RW;

			create_mapping(&map);
		}

Hence, fix it by using phys_addr_t type for variables kernel_x_start
and kernel_x_end.

cca547e9aa ARM: 8249/1: mm: dump: don't skip regions
Currently the arm page table dumping code starts dumping page tables
from USER_PGTABLES_CEILING. This is unnecessary for skipping any entries
related to userspace as the swapper_pg_dir does not contain such
entries, and results in a couple of unfortuante side effects.

Firstly, any kernel mappings which might exist below
USER_PGTABLES_CEILING will not be accounted in the dump output. This
masks any entries erroneously created below this address.

Secondly, if the final page table entry walked is part of a valid
mapping the page table dumping code will not log the region this entry
is part of, as the final note_page call in walk_pgd will trigger an
early return when 0 < USER_PGTABLES_CEILING. Luckily this isn't seen on
contemporary systems as they typically don't have enough RAM to extend
the linear mapping right to the end of the address space.

Due to the way addr is constructed in the walk_* functions, it can never
be less than USER_PGTABLES_CEILING when walking the page tables, so it
is not necessary to avoid dereferencing invalid table addresses. The
existing checks for st->current_prot and st->marker[1].start_address are
sufficient to ensure we will not print and/or dereference garbage when
trying to log information.

This patch removes both problematic uses of USER_PGTABLES_CEILING from
the arm page table dumping code, preventing both of these issues. We
will now report any low mappings, and the final note_page call will not
return early, ensuring all regions are logged.

7a9f0604bd ARM: dts: imx51-babbage: Fix ULPI PHY reset modelling
GPIO2_5 is the reset GPIO for the USB3317 ULPI PHY. Instead of modelling it as
a regulator, the correct approach is to use the 'reset_gpios' property of the
"usb-nop-xceiv" node.

GPIO1_7 is the reset GPIO for the USB2517 USB hub. As we currently don't have
dt bindings to describe a HUB reset, let's keep using the regulator approach.

Rename the regulator to 'reg_hub_reset' to better describe its function and bind
it with the USB host1 port instead.

USB host support has been introduced by commit 9bf206a9d1 ("ARM: dts:
imx51-babbage: Add USB Host1 support"), which landed in 3.16 and it seems that
USB has only been functional due to previous bootloader initialization.

With this patch applied we can get USB host to work without relying on the
bootloader.

999f934de1 ARM: omap5/dra7xx: Enable booting secondary CPU in HYP mode
If the boot loader enables HYP mode on the boot CPU, the secondary CPU
also needs to call into the ROM to switch to HYP mode before booting.
The firmwares on the omap5 and dra7xx unfortunately do not take care
of this, so it has to be handled by the kernel.

This patch is based on "[PATCH 2/2] ARM: OMAP5: Add HYP mode entry support
for secondary CPUs" by Santosh Shilimkar <santosh.shilimkar@ti.com>,
except this version does not require a compile time CONFIG to control
if it should enable HYP mode or not, it simply does it based on the mode
of the boot CPU, so it works whether the CPU boots in SVC or HYP mode,
and should even work as a guest kernel inside kvm if qemu decides to
support emulating the omap5 or dra7xx.

afc9d590b8 ARM: dra7xx: Fix counter frequency drift for AM572x errata i856
Errata i856 for the AM572x (DRA7xx) points out that the 32.768KHz external
crystal is not enabled at power up.  Instead the CPU falls back to using
an emulation for the 32KHz clock which is SYSCLK1/610.  SYSCLK1 is usually
20MHz on boards so far (which gives an emulated frequency of 32.786KHz),
but can also be 19.2 or 27MHz which result in much larger drift.

Since this is used to drive the master counter at 32.768KHz * 375 /
2 = 6.144MHz, the emulated speed for 20MHz is of by 570ppm, or about 43
seconds per day, and more than the 500ppm NTP is able to tolerate.

Checking the CTRL_CORE_BOOTSTRAP register can determine if the CPU
is using the real 32.768KHz crystal or the emulated SYSCLK1/610, and
by known that the real counter frequency can be determined and used.
The real speed is then SYSCLK1 / 610 * 375 / 2 or SYSCLK1 * 75 / 244.

It seems that ever since (536f6b9 mmc: dw_mmc: Reset DMA before

on rk3288-evb.  They were a little unhappy before that change, but
after that change they're REALLY unhappy.

It turns out that the above fix happens to fix a corruption when
reading card information during probe time.  Without the fix we didn't
detect that high speed SD cards could actually support high speed.
With the fix we suddenly detect that they're high speed and we try to
use them at 50MHz.  That doesn't work so well on EVB with the default
drive strength (maybe because there are two physical SD card slots
hooked up to the same pin?).

Fix the problem by bumping up the drive strength of the sdmmc lines.

60815cf2e0 kernel: Provide READ_ONCE and ASSIGN_ONCE
As discussed on LKML http://marc.info/?i=54611D86.4040306%40de.ibm.com
 ACCESS_ONCE might fail with specific compilers for non-scalar accesses.
 
 Here is a set of patches to tackle that problem.
 
 The first patch introduce READ_ONCE and ASSIGN_ONCE. If the data structure
 is larger than the machine word size memcpy is used and a warning is emitted.
 The next patches fix up several in-tree users of ACCESS_ONCE on non-scalar
 types.
 
 This merge does not yet contain a patch that forces ACCESS_ONCE to work only
 on scalar types. This is targetted for the next merge window as Linux next
 already contains new offenders regarding ACCESS_ONCE vs. non-scalar types.

bfc7249cc2 Please consider pulling the clk framework changes toward 3.19. It is
much later than usual due to several last minute bugs that had to be
 addressed. As usual the majority of changes are new drivers and
 modifications to existing drivers. The core recieved many fixes along
 with the groundwork for several large changes coming in the future which
 will better parition clock providers from clock consumers.
