If we don't come out of a clean reset, make sure no IRQ is fired before
everything is setup by resetting the IPU before activating the interrupt
handlers.

This cleans up the display controller microcode setup in ipu_dc_init_sync
a little bit. The microcode template words for DI0 and DI1 are properly
separated to avoid a clash when DI1 is active in interlaced mode at the
same time as DI0 in non-interlaced mode.
A comment is added to explain the meaning of the sync counter.

While https was always supported on linuxtv.org, only in
Dec 3 2015 the website is using valid certificates.
As we're planning to drop pure http support on some
future, change the references at DRM include and at
the ipu-v3 driver to point to the https://linuxtv.org
URL instead.

The crtc child device driver shouldn't have to modify the of_node of its
platform device in the probe function. Instead, let the IPU core driver
set the of_node when the platform device is created.
Also reorder the client_reg array so the elements are in port id order
(CSIs first, then DIs).

The support for interlaced video modes seems to be broken; we don't use
anything other than the vtotal/htotal from the timing information to
define the various sync counters.
Freescale patches for interlaced video support contain an alternative
sync counter setup, which we include here. This setup produces the
hsync and vsync via the normal counter 2 and 3, but moves the display
enable signal from counter 5 to counter 6. Therefore, we need to
change the display controller setup as well.
The corresponding Freescale patches for this change are:
iMX6-HDMI-support-interlaced-display-mode.patch
IPU-fine-tuning-the-interlace-display-timing-for-CEA.patch
This produces a working interlace format output from the IPU.

set_irq_flags is ARM specific with custom flags which have genirq
equivalents. Convert drivers to use the genirq interfaces directly, so we
can kill off set_irq_flags. The translation of flags is as follows:
IRQF_VALID -> !IRQ_NOREQUEST
IRQF_PROBE -> !IRQ_NOPROBE
IRQF_NOAUTOEN -> IRQ_NOAUTOEN
For IRQs managed by an irqdomain, the irqdomain core code handles clearing
and setting IRQ_NOREQUEST already, so there is no need to do this in
.map() functions and we can simply remove the set_irq_flags calls. Some
users also modify IRQ_NOPROBE and this has been maintained although it
is not clear that is really needed. There appears to be a great deal of
blind copy and paste of this code.

Most interrupt flow handlers do not use the irq argument. Those few
which use it can retrieve the irq number from the irq descriptor.
Remove the argument.
Search and replace was done with coccinelle and some extra helper
scripts around it. Thanks to Julia for her help!

Pull dmaengine updates from Vinod Koul:
"This time we have aded a new capability for scatter-gathered memset
using dmaengine APIs. This is supported in xdmac & hdmac drivers
We have added support for reusing descriptors for examples like video
buffers etc. Driver will follow
The behaviour of descriptor ack has been clarified and documented
New devices added are:
- dma controller in sun[457]i SoCs
- lpc18xx dmamux
- ZTE ZX296702 dma controller
- Analog Devices AXI-DMAC DMA controller
- eDMA support for dma-crossbar
- imx6sx support in imx-sdma driver
- imx-sdma device to device support
Other:
- jz4780 fixes
- ioatdma large refactor and cleanup for removal of ioat v1 and v2
which is deprecated and fixes
- ACPI support in X-Gene DMA engine driver
- ipu irq fixes
- mvxor fixes
- minor fixes spread thru drivers"
[ The Kconfig and Makefile entries got re-sorted alphabetically, and I
handled the conflict with the new Intel integrated IDMA driver by
slightly mis-sorting it on purpose: "IDMA64" got sorted after "IMX" in
order to keep the Intel entries together. I think it might be a good
idea to just rename the IDMA64 config entry to INTEL_IDMA64 to make
the sorting be a true sort, not this mismash.
Also, this merge disables the COMPILE_TEST for the sun4i DMA
controller, because it does not compile cleanly at all. - Linus ]

The IPU code was installing its chained interrupt handler (which enables

kexec. Fix this by converting to irq_set_chained_handler_and_data().

This patch consolidates the different interface_pix_fmt, pixel_fmt, pix_fmt,
and pixfmt variables to a common name "bus_format" wherever they describe the
pixel format on the bus between display controller and encoder hardware.
At the same time, it renames imx_drm_panel_format to imx_drm_set_bus_format.

imx-drm internally misused the V4L2_PIX_FMT constants, which are supposed to
describe the pixel format of frame buffers in memory, to describe the pixel
format on the bus between the display controller and the encoder hardware.
Now that MEDIA_BUS_FMT constants are available to drm drivers, use those
instead.

We can use the DIV_ROUND_CLOSEST() macro when calculating the DI
clock divider, rounded to nearest int.

On some monitors, high resolution modes are not working, exhibiting
pixel column truncation problems (for example, 1280x1024 displays as
1280x1022).
The function ipu_di_adjust_videomode() aims to fix these issues by
adjusting a passed videomode to IPU restrictions. The function can
be called from the drm_crtc_helper_funcs->mode_fixup() methods.

The functions ipu_dc_enable() and ipu_dc_disable() enable/disable the DC
globally in the IPU_CONF register, but the DC is used by multiple clients
on different DC channels. So make sure to only disable/enable the DC
globally based on a use counter.

In order to have subsytem agnostic media bus format definitions we've
moved media bus definition to include/uapi/linux/media-bus-format.h and
prefixed enum values with MEDIA_BUS_FMT instead of V4L2_MBUS_FMT.
Reference new definitions in the ipu-v3 driver.

This driver uses GENERIC_IRQ_CHIP, so it needs to select GENERIC_IRQ_CHIP to
avoid build error.
Fixes below build errors:

ERROR: "irq_gc_mask_clr_bit" [drivers/gpu/ipu-v3/imx-ipu-v3.ko] undefined!

Unified base offset and Y plane offset into a single variable,
moved all ipu_cpmem_set_buffer calls to a single location.
Removed NV21 and NV61 for now. The IDMAC doesn't understand U/V
order for chroma interleaved formats, so we'd need to work around
this by implenting U/V switching via the CSC unit.
