670734f558 ARM: dts: exynos: Add all CPUs in cooling maps
Each CPU can (and does) participate in cooling down the system but the
DT only captures a handful of them, normally CPU0, in the cooling maps.
Things work by chance currently as under normal circumstances its the
first CPU of each cluster which is used by the operating systems to
probe the cooling devices. But as soon as this CPU ordering changes and
any other CPU is used to bring up the cooling device, we will start
seeing failures.

Also the DT is rather incomplete when we list only one CPU in the
cooling maps, as the hardware doesn't have any such limitations.

Update cooling maps to include all devices affected by individual trip
points.

b803211825 ARM: dts: exynos: Remove double SD card detect pin inversion
The SDHCI standard, MMC host controller bindings and MMC core defines
card detect pin as active low.  Therefore there is no point to invert it
twice.

965228d33c ARM: dts: exynos: Configure Midas SD card CD pin
This pin is externally pulled up, so we need to disable the SoC's
internal pull down resistor to allow it to function properly.

This pin is externally pulled up, so we should disable the SoC's
pull down resistor in order for the interrupt to function properly.

492413dd6d ARM: dts: exynos: Add pinctrl config for Midas keys
This pins are externally pulled up, and so we should explicitly
configure them to disable the SoC-internal pull-downs. Previously
we relied on the bootloader doing this in order to allow the buttons
to function properly.

43efe4fab7 ARM: dts: exynos: Add max77693 pinctrl config for Midas
Currently, we assume that the bootloader has correctly configured
the interrupt pin for max77693. This might not actually be the case -
so it's better to configure it explicitly.

ca1378d155 ARM: dts: exynos: Bring order in fixed-regulators naming in Midas boards
exynos4412-midas.dtsi is base for galaxy-s3.dtsi and n710x.dts.  All of
them contain fixed regulators named "voltage-regulator-X".  Their
indexes got mixed up while splitting common code in commit c769eaf7a8
("ARM: dts: exynos: Split Trats2 DTS in preparation for Midas boards").

33b9e7195d ARM: dts: exynos: Remove unnecessary address/size properties in Midas boards
The children of regulators node do not have reg/ranges properties.  Move the
children up one level, get rid of regulators node and remove
address-cells and size-cells properties.  This fixes warnings for
Exynos4412 Midas family boards:

        /regulators: unnecessary #address-cells/#size-cells without "ranges" or child "reg" property

out of Trats2 into a common Midas DTSI and a common "Galaxy S3" DTS.
