Fix up inconsistent usage of upper and lowercase letters in "Samsung"
and "Exynos" names.
"SAMSUNG" and "EXYNOS" are not abbreviations but regular trademarked
names. Therefore they should be written with lowercase letters starting
with capital letter.
The lowercase "Exynos" name is promoted by its manufacturer Samsung
Electronics Co., Ltd., in advertisement materials and on website.
Although advertisement materials usually use uppercase "SAMSUNG", the
lowercase version is used in all legal aspects (e.g. on Wikipedia and in
privacy/legal statements on
https://www.samsung.com/semiconductor/privacy-global/).

Commit 2b7681326d ("drm/exynos: hdmi: remove the i2c drivers and use")
merged to v3.15 kernel added a required 'ddc' property to Exynos HDMI
device tree bindings, which should point to i2c bus used for handling DDC
(mainly reading display's EDID information). It has been enough time to
convert all boards to use new bindings, but sadly due to copy/paste design
the old approach using separate node with 'samsung,exynos4210-hdmiddc'
compatible was used also for many new boards. This patch finally converts
all boards to the new approach and unifies HDMI DDC definition across all
Exynos boards.

During my research I found that some of the requirements for the memory
buffers for MFC v6+ devices were blindly copied from the previous (v5)
version and simply turned out to be excessive. The relaxed requirements
are applied by the recent patches to the MFC driver and the driver is
now fully functional even without the reserved memory blocks for all
v6+ variants. This patch removes those reserved memory nodes from all
boards having MFC v6+ hardware block.

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'.

Exynos5420 and Exynos5800 boards boot from big core (A15) but
Exynos5422 boards choose otherwise: LITTLE core (A7) (on Exynos5422 this
is property of the board - configurable by pulling up/down gpg2-1).
To make user-visible CPU ordering more consistent the 'cpus' node was
overridden by exynos5422-cpus.dtsi.
However this is a little bit ugly and error-prone. Overriding the CPU
child nodes requires to basically reverse what was done initially in
exynos5420.dtsi.
Instead, split CPU configuration entirely to separate files which should
be included by board DTS.

The Exynos5420 SoC has 3 sets of 8 pads used as data lines for the 3
MMC/SD/SDIO slots. These needs to be muxed as SD_n_DATA instead of a
GPIO or external interrupt to allow the MMC controller to communicate
with the attached cards or SDIO devices.
Which data lines needs to be muxed as SD_n_DATA depends on the bus
width used for data transfer:
* bus-width = <1> needs SD_n_DATA[0]
* bus-width = <4> needs SD_n_DATA[0-3]
* bus-width = <8> needs SD_n_DATA[0-7]
The Exynos5250-pinctrl.dtsi file that defines the groups of pins has
SD_n_DATA[0] muxed for both sdn_bus1 and sdn_bus4 so just one of them
needs to be included in the device node's pinctrl property.
But Exynos5420-pinctrl has a different definition and only includes
SD_n_DATA[1-3] for sdn_bus4. So for a bus-width = <4>, both sdn_bus1
and sdn_bus4 have to be in the dev pinctrl to mux all the needed pads.
It seems all Exynos5420 boards had just cargo cult the pinctrl lines
assuming that sdn_bus4 also included SD_n_DATA[0] and it only works
because the bootloader muxes the pads correctly. But that is not the
case for the devices not used by the bootloader such as WiFi modules.
Add sdn_bus1 too in the nodes pinctrl to not rely on the bootloader.
