Merge branch 'drm-dwhdmi-devel' of git://ftp.arm.linux.org.uk/~rmk/linux-arm into drm-next
Here are some development updates for the Synopsis Designware HDMI driver,
which clean up some of the code, and start preparing to add audio support
to the driver. This series of patches are based on a couple of dependent
commits from the ALSA tree.
Briefly, the updates are:
- move comments which should have moved with the phy values to the IMX
part of the driver.
- clean up the phy configuration: to all lookups before starting to
program the phy.
- clean up the HDMI clock regenerator code
- use the drm_hdmi_avi_infoframe_from_display_mode() helper which allows
the code to be subsequently simplified
- remove the unused 'regmap' pointer in struct dw_hdmi
- use the bridge drm device rather than the connector (we're the bridge
code)
- remove private hsync/vsync/interlaced flags, getting them from the
DRM mode structure instead.
- implement interface functions to support audio - setting the audio
sample rate, and enabling the audio clocks.
- removal of broken pixel repetition support
- cleanup DVI vs HDMI sink handling
- enable audio only if connected device supports audio
- avoid double-enabling bridge in the sink path (once in mode_set, and
again in commit)
- rename mis-named dw_hdmi_phy_enable_power()
- fix bridge enable/disable handing, so a plug-in event doesn't
reconfigure the bridge if DRM has disabled the output
- fix from Vladimir Zapolskiy for the I2CM_ADDRESS macro name
These are primerily preparitory patches for the AHB audio driver and
the I2S audio driver (from Rockchip) for this IP.

The reason is the incorrect assumption in fpu_copy(), that FNSAVE
can be executed from math-emu kernels as well.
Don't try to copy the registers, the soft state will be copied
by fork anyway, so the child task inherits the parent task's
soft math state.
With this fix applied math-emu kernels boot up fine on modern
hardware and the 'no387 nofxsr' boot options.

DRM - radeon: Don't link train DisplayPort on HPD until we get the dpcd
Most of the time this isn't an issue since hotplugging an adaptor will
trigger a crtc mode change which in turn, causes the driver to probe
every DisplayPort for a dpcd. However, in cases where hotplugging
doesn't cause a mode change (specifically when one unplugs a monitor
from a DisplayPort connector, then plugs that same monitor back in
seconds later on the same port without any other monitors connected), we
never probe for the dpcd before starting the initial link training. What
happens from there looks like this:
- GPU has only one monitor connected. It's connected via
DisplayPort, and does not go through an adaptor of any sort.
- User unplugs DisplayPort connector from GPU.
- Change in HPD is detected by the driver, we probe every
DisplayPort for a possible connection.
- Probe the port the user originally had the monitor connected
on for it's dpcd. This fails, and we clear the first (and only
the first) byte of the dpcd to indicate we no longer have a
dpcd for this port.
- User plugs the previously disconnected monitor back into the
same DisplayPort.
- radeon_connector_hotplug() is called before everyone else,
and tries to handle the link training. Since only the first
byte of the dpcd is zeroed, the driver is able to complete
link training but does so against the wrong dpcd, causing it
to initialize the link with the wrong settings.
- Display stays blank (usually), dpcd is probed after the
initial link training, and the driver prints no obvious
messages to the log.
In theory, since only one byte of the dpcd is chopped off (specifically,
the byte that contains the revision information for DisplayPort), it's
not entirely impossible that this bug may not show on certain monitors.
For instance, the only reason this bug was visible on my ASUS PB238
monitor was due to the fact that this monitor using the enhanced framing
symbol sequence, the flag for which is ignored if the radeon driver
thinks that the DisplayPort version is below 1.1.

mm: make page pfmemalloc check more robust
Commit
c48a11c7ad26 ("netvm: propagate page->pfmemalloc to skb") added
checks for page->pfmemalloc to __skb_fill_page_desc():
if (page->pfmemalloc && !page->mapping)
skb->pfmemalloc = true;
It assumes page->mapping == NULL implies that page->pfmemalloc can be
trusted. However, __delete_from_page_cache() can set set page->mapping
to NULL and leave page->index value alone. Due to being in union, a
non-zero page->index will be interpreted as true page->pfmemalloc.
So the assumption is invalid if the networking code can see such a page.
And it seems it can. We have encountered this with a NFS over loopback
setup when such a page is attached to a new skbuf. There is no copying
going on in this case so the page confuses __skb_fill_page_desc which
interprets the index as pfmemalloc flag and the network stack drops
packets that have been allocated using the reserves unless they are to
be queued on sockets handling the swapping which is the case here and
that leads to hangs when the nfs client waits for a response from the
server which has been dropped and thus never arrive.
The struct page is already heavily packed so rather than finding another
hole to put it in, let's do a trick instead. We can reuse the index
again but define it to an impossible value (-1UL). This is the page
index so it should never see the value that large. Replace all direct
users of page->pfmemalloc by page_is_pfmemalloc which will hide this
nastiness from unspoiled eyes.
The information will get lost if somebody wants to use page->index
obviously but that was the case before and the original code expected
that the information should be persisted somewhere else if that is
really needed (e.g. what SLAB and SLUB do).

drm/layerscape: Add Freescale DCU DRM driver
This patch add support for Two Dimensional Animation and Compositing
Engine (2D-ACE) on the Freescale SoCs.
2D-ACE is a Freescale display controller. 2D-ACE describes
the functionality of the module extremely well its name is a value
that cannot be used as a token in programming languages.
Instead the valid token "DCU" is used to tag the register names and
function names.
The Display Controller Unit (DCU) module is a system master that
fetches graphics stored in internal or external memory and displays
them on a TFT LCD panel. A wide range of panel sizes is supported
and the timing of the interface signals is highly configurable.
Graphics are read directly from memory and then blended in real-time,
which allows for dynamic content creation with minimal CPU
intervention.
The features:
(1) Full RGB888 output to TFT LCD panel.
(2) Blending of each pixel using up to 4 source layers
dependent
on size of panel.
(3) Each graphic layer can be placed with one pixel resolution
in either axis.
(4) Each graphic layer support RGB565 and RGB888 direct colors
without alpha channel and BGRA8888 BGRA4444 ARGB1555 direct
colors
with an alpha channel and YUV422 format.
(5) Each graphic layer support alpha blending with 8-bit
resolution.
This is a simplified version, only one primary plane, one
framebuffer, one crtc, one connector and one encoder for TFT
LCD panel.

irqchip/crossbar: Restore set_wake functionality
The TI crossbar irqchip doesn't provides any facility to configure the
wakeup sources, but the conversion to hierarchical irqdomains set the
irq_set_wake callback to irq_chip_set_wake_parent. The parent chip
(OMAP wakeupgen) has no irq_set_wake function either so the call will
fail with -ENOSYS. As a result the irq_set_wake() call in the resume
path will trigger an 'Unbalanced wake disable' warning.
Before the conversion the GIC irqchip was the top level irqchip and
correctly flagged with IRQCHIP_SKIP_SET_WAKE.
Restore the correct behaviour by removing the irq_set_type callback
from the crossbar irqchip and set the IRQCHIP_SKIP_SET_WAKE flag which
lets the irq_set_irq_wake() call from the driver succeed.

irqchip/crossbar: Restore the mask on suspend behaviour
The ARM GIC requires that all interrupts which are not used as a
wakeup source have to be masked during suspend.
The conversion of the crossbar irqchip to hierarchical irq domains
failed to mark the crossbar irqchip with the IRQCHIP_MASK_ON_SUSPEND
flag and therefor broke the suspend requirement of the GIC.
Before the conversion the flags were visible because the GIC was the
top level irqchip. After the conversion the crossbar irqchip is the
top level irq chip whose flags are evaluated in suspend_device_irq().
As the flag is not set the masking of the non-wakeup irqs is not
invoked which breaks suspend.
Add the IRQCHIP_MASK_ON_SUSPEND flag to the crossbar irqchip, so the
GIC interrupts get masked properly.
