1a96571db0 Enable 32 bit flash support for iMX21ADS board
The kernel configuration for the i.MX21ADS board (imx_v4_v5_defconfig)
doesn't enable 32 bit flash support. But the i.MX21ADS specific code
adds a 32 bit flash device, resulting in a kernel that refuses to
boot.

bb6e8fb30b arm/tegra: remove __initdata annotation from pinmux tables
Instead of reshuffling what functions in the pinmux paths should be
__init and thus could keep references to __initdata, let's just remove
the annotations for now -- the tables are moving to device tree in the
next version anyway and the whole subsystem is being wired up. We will
go back and re-annotate where appropriate once things settle down.

a58116f331 arm/tegra: Use bus notifiers to trigger pinmux setup
Currently, the Tegra pinmux is initialized at different times when booting
with and without device tree:

Without device tree:

1) Pinmux and GPIO drivers are registered.
2) Pinmux is configured.
3) All other drivers are registered.

With device tree:

1) All drivers are registered and probed, including pinmux and GPIO.
2) Pinmux is configured.

This change modifies board-pinmux.c to detect pinmux and GPIO driver
registration using bus notifiers. This allows pinmux configuration to
happen immediately after the pinmux driver is probed, irrespective of
whether the pinmux driver is manually registered by board-pinmux.c, or
if it's instantiated during device tree parsing.

To support this with device tree, the pinmux init functions must be
called prior to instantiating devices from device tree, so that the
notifiers are set up before-hand.

54862bf009 arm/tegra: Refactor board-*-pinmux.c to share code
This moves the implementation of *_pinmux_init() into a single location.
The board-specific pinmux data is left in each board's own file. This
will allow future changes that set up the pinmux in a more complex
fashion to do so without duplicating that code in each board's pinmux
file.

b49cae59e1 arm/tegra: Fix mistake in Trimslice's pinmux
Pin group PTA does not support function RSVD3. However, the current
pinmux driver doesn't check this when setting RSVD functions, and ends
up writing 3 to the HW register. 3 is actually represented by function
GMI, so update the pinmux table to request that instead in order to
obtain the same register programming without requesting invalid
configurations.

Rather than modifying seaboard_pinmux[] using ventana_pinmux[], split
seaboard_pinmux[] into common_pinmux[] and seaboard_pinmux[], and then
actually apply common_pinmux[] always, followed by the appopriate one
of seaboard_pinmux[] or ventana_pinmux[].

The Harmony pinmux table is already set up to mux the PCIe signals onto
the appropriate pin groups. Don't manually fiddle with the pinmux in the
Harmony PCIe setup code.

Merge note: This will have a merge conflict with Peter De Schrijver's
"arm/tegra: prepare pinmux code for multiple tegra variants" due to
context. When merging the two, make sure to also remove the include
of <mach/pinmux-tegra20.h> that his patch added, since it's no longer
needed after this patch.

1a4a30c849 arm/tegra: Add AUXDATA for tegra-pinmux and tegra-gpio
The pinctrl device name is included in the pinctrl map table, and used
as a parameter to pin_config_*() functions. Hence, it must be the same
for non-DT and DT kernels. Add AUXDATA to cause this.

The GPIO device name will be used by the pinmux/GPIO initialization code
in a later patch, and needs to stay constant.

For now, as semaphores interaction with VTd causes random issues on
SNB, we do not enable them by default. But they can still be enabled
via the semaphores=1 kernel parameter.

7317c75e66 drm/i915: don't set unpin_work if vblank_get fails
This fixes a race where we may try to finish a page flip and decrement
the refcount even if our vblank_get failed and we ended up with a
spurious flip pending interrupt.

Fixes https://bugs.freedesktop.org/show_bug.cgi?id=34211.

c0f372b374 drm/i915: By default, enable RC6 on IVB and SNB when reasonable
RC6 should always work on IVB, and should work on SNB whenever IO
remapping is disabled. RC6 never works on Ironlake. Make the default
value for the parameter follow these guidelines. Setting the value
to either 0 or 1 will force the specified behavior.

8bc1f85c02 iommu: Export intel_iommu_enabled to signal when iommu is in use
In i915 driver, we do not enable either rc6 or semaphores on SNB when dmar
is enabled. The new 'intel_iommu_enabled' variable signals when the
iommu code is in operation.

5222008580 drm/i915/sdvo: Include LVDS panels for the IS_DIGITAL check
We were checking whether the supplied edid matched the connector it was
read from. We do this in case a DDC read returns an EDID for another
device on a multifunction or otherwise interesting card. However, we
failed to include LVDS as a digital device and so rejecting an otherwise
valid EDID.

Fixes the detection of the secondary SDVO LVDS panel on the Libretto
W105.

4ed0b57745 drm/i915: prevent division by zero when asking for chipset power
This prevents an in-kernel division by zero which happens when we are
asking for i915_chipset_val too quickly, or within a race condition
between the power monitoring thread and userspace accesses via debugfs.

The issue can be reproduced easily via the following command:
while ``; do cat /sys/kernel/debug/dri/0/i915_emon_status; done

This is particularly dangerous because it can be triggered by
a non-privileged user by just reading the debugfs entry.

This issue was also found independently by Konstantin Belousov
<kostikbel@gmail.com>, who proposed a similar patch.
