Of-graph bindings should describe ports present in the device, not the
devices it can be connected to. The patch replaces verbose description
with shorter but more precise one. While at it clock related properties
are moved to the main node as it is their actual location.

'interrupt-parent' is often documented as part of define bindings, but
it is really outside the scope of a device binding. It's never required
in a given node as it is often inherited from a parent node. Or it can
be implicit if a parent node is an 'interrupt-controller' node. So
remove it from all the binding files.

Proper support for Decon's hardware window no 4 and 5 require enabling
a few more clocks ("aclk_smmu_decon1x", "aclk_xiu_decon1x",
"pclk_smmu_decon1x"). Add those clocks to required clocks list in Decon's
dt bindings.

Pull ARM SoC platform updates from Arnd Bergmann:
"In the SoC branch we normally collect classic arch/arm/mach-*
contents, i.e. C code changes for SoC platforms. This release cycle
the diffstat is quite nice, in that we're removing 3x the amount of
code that's being added.
The main reason for this is that there's a removal of camera drivers
for Freescale i.MX chips (driver was removed so the device
registration isn't needed any more). There's also removal of display
initialization code for OMAP that is no longer needed.
The rest are mostly minor tweaks and cleanups; constification on
Samsung platforms, cleanup of ux500 platform data, purge of other
unused platform data/device seutp on i.MX and other good stuff.
New SoC support this cycle is for two Allwinner platforms, H2+ and
V3s"

This patch enables getting a HPD GPIO descriptor quicker.
The exynos-hdmi driver uses "hpd" for HDMI hot plug detection.
static int hdmi_resources_init(struct hdmi_context *hdata)
{
...
hdata->hpd_gpio = devm_gpiod_get(dev, "hpd", GPIOD_IN);
...
}
This calls 'of_find_gpio()' and it generates the GPIO consumer ID by referring
GPIO suffix. So 'hpd-gpios' is preferred on getting a GPIO descriptor.
However, if the device tree uses 'hpd-gpio', then the exynos-hdmi driver
always retries to get a GPIO descriptor because the first GPIO suffix is not
'gpio' but 'gpios'. So you always see the debug message below.
of_get_named_gpiod_flags: can't parse 'hpd-gpios' property of node '/soc/hdmi@14530000[0]'
Use the preferred property, 'hpd-gpios' instead of 'hpd-gpio'.

This patch adds a exynos5420 driver data to support mic_bypass
option to bypass the mic from display out path.
The mic(Mobile image compressor) compresses RGB data from fimd
and send the compressed data to the mipi dsi.
The bypass option can be founded from system register and the bit
is 11. The option bit has been introduced since exynos5420. The
only difference between exynos5250 and exynos5420/exynos5422 is
existence of the bit. Until the MIC is defined and enabled from
device tree, the bypass mic will be default option.

This patch supports mipi dsi for exynos5422. The dsi register
offsets of the exynos5422 are similar with exynos5433. However,
the values of the registers are quite different from the
exynos5433. For example, the exynos5422 uses sw reset like
previous chips.

This is a quite large renaming to consolidate display related bindings
into a single "display" directory from various scattered locations of
video, drm, gpu, fb, mipi, and panel. The prior location was somewhat
based on the Linux driver location, but bindings should be independent
of that.
