Pull first batch of arm-soc cleanups from Olof Johansson:
"These cleanups are basically all over the place. The idea is to
collect changes with minimal impact but large number of changes so we
can avoid them from distracting in the diffstat in the other series.
A significant number of lines get removed here, in particular because
the ixp2000 and ixp23xx platforms get removed. These have never been
extremely popular and have fallen into disuse over time with no active
maintainer taking care of them. The u5500 soc never made it into a
product, so we are removing it from the ux500 platform.
Many good cleanups also went into the at91 and omap platforms, as has
been the case for a number of releases."

In preparation for device tree, this patch changes how the DSI pins are
configured. The current configuration method is only doable with board
files and the configuration data is OMAP specific.
This patch moves the configuration data to the panel's platform data,
and the data can easily be given via DT in the future. The configuration
data format is also changed to a generic one which should be suitable
for all platforms.
The new format is an array of pin numbers, where the array items start
from clock + and -, then data1 + and -, and so on. For example:
{
0, // pin num for clock lane +
1, // pin num for clock lane -
2, // pin num for data1 lane +
3, // pin num for data1 lane -
...
}
The pin numbers are translated by the DSI driver and used to configure
the hardware appropriately.

For now, it just contains the hack for cirrusfb on Amiga, which is moved
out of <video/vga.h> with some slight modifications (use raw_*() instead of
z_*(), which are defined on all m68k platforms).
This makes it safe to include <video/vga.h> in all contexts. Before it
could fail to compile with

Pull ARM platform updates from Russell King:
"This covers platform stuff for platforms I have a direct interest in
(iow, I have the hardware). Essentially:
- as we no longer support any other Acorn platforms other than RiscPC
anymore, we can collect all that code into mach-rpc.
- convert Acorn expansion card stuff to use IRQ allocation functions,
and get rid of NO_IRQ from there.
- cleanups to the ebsa110 platform to move some private stuff out of
its header files.
- large amount of SA11x0 updates:
- conversion of private DMA implementation to DMA engine support
(this actually gives us greater flexibility in drivers over the old
API.)
- re-worked ucb1x00 updates - convert to genirq, remove sa11x0
dependencies, fix various minor issues
- move platform specific sa11x0 framebuffer data into platform files
in arch/arm instead of keeping this in the driver itself
- update sa11x0 IrDA driver for DMA engine, and allow it to use DMA
for SIR transmissions as well as FIR
- rework sa1111 support for genirq, and irq allocation
- fix sa1111 IRQ support so it works again
- use sparse IRQ support
After this, I have one more pull request remaining from my current
set, which I think is going to be the most problematical as it
generates 8 conflicts."

Russell.

sh_mipi uses some clocks, but the method of setup depends on CPU.
Current SuperH (like sh73a0) can control all of these clocks
by CPG (Clock Pulse Generator).
It means we can control it by clock framework only.
But on sh7372, it needs CPG settings AND sh_mipi PHYCTRL::PLLDS,
and only sh7372 has PHYCTRL::PLLDS.
But on current sh_mipi driver, PHYCTRL::PLLDS of sh7372 was
overwrote since the callback timing of clock setting was changed
by c2658b70f06108361aa5024798f9c1bf47c73374
(fbdev: sh_mipi_dsi: fixup setup timing of sh_mipi_setup()).
To solve this issue, this patch adds extra .phyctrl.
This patch adds detail explanation for unclear mipi settings
and fixup wrong PHYCTRL::PLLDS value for ap4evb (0xb -> 0x6).

A hardware bug in the OMAP4 HDMI PHY causes physical damage to the board
if the HDMI PHY is kept powered on when the cable is not connected.
This patch solves the problem by adding hot-plug-detection into the HDMI
IP driver. This is not a real HPD support in the sense that nobody else
than the IP driver gets to know about the HPD events, but is only meant
to fix the HW bug.
The strategy is simple: If the display device is turned off by the user,
the PHY power is set to OFF. When the display device is turned on by the
user, the PHY power is set either to LDOON or TXON, depending on whether
the HDMI cable is connected.
The reason to avoid PHY OFF when the display device is on, but the cable
is disconnected, is that when the PHY is turned OFF, the HDMI IP is not
"ticking" and thus the DISPC does not receive pixel clock from the HDMI
IP. This would, for example, prevent any VSYNCs from happening, and
would thus affect the users of omapdss. By using LDOON when the cable is
disconnected we'll avoid the HW bug, but keep the HDMI working as usual
from the user's point of view.

Overlays are currently enabled and disabled with a boolean in the struct
omap_overlay_info. The overlay info is set with ovl->set_overlay_info(),
and made into use with mgr->apply().
This doesn't work properly, as the enable/disable status may affect also
other overlays, for example when using fifo-merge. Thus the enabling and
disabling of the overlay needs to be done outside the normal overlay
configuration.
This patch achieves that by doing the following things:
1) Add function pointers to struct omap_overlay: enable(), disable() and
is_enabled(). These are used to do the obvious. The functions may block.
2) Move the "enabled" field from struct omap_overlay to ovl_priv_data.
3) Add a new route for settings to be applied to the HW, called
"extra_info". The status of the normal info and extra_info are tracked
separately.
The point here is to allow the normal info to be changed and
applied in non-blocking matter, whereas the extra_info can only be
changed when holding the mutex. This makes it possible to, for example,
set the overlay enable flag, apply it, and wait until the HW has taken
the flag into use.
This is not possible if the enable flag would be in the normal info, as
a new value for the flag could be set at any time from the users of
omapdss.

The current code uses dsi_video_mode_enable/disable functions to
enable/disable DISPC output for video mode displays. For command mode
displays we have no notion in the DISPC side of whether the panel is
enabled, except when a dss_mgr_start_update() call is made.
However, to properly maintain the DISPC state in apply.c, we need to
know if a manager used for a manual update display is currently in use.
This patch achieves that by changing dsi_video_mode_enable/disable to
dsi_enable/disable_video_output, which is called by both video and
command mode displays. For video mode displays it starts the actual
pixel stream, as it did before. For command mode displays it doesn't do
anything else than mark that the manager is currently in use.

Current way of handling overlay-manager links is a bit strange: each
manager has a static array, containing pointers to all the overlays
(even those used by other managers). The overlays contain a pointer to
the manager being used.
This patch makes the system a bit saner: each manager has a linked list
of overlays, and only the overlays linked to that manager are in the
list.
