- Interface PMIC (Maxim MAX77836, MUIC, fuel-gauge, charger)
- RTC of Exynos3250
- ADC of Exynos3250 with NTC thermistor
- I2S of Exynos3250
- TMU of Exynos3250
- MFC of Exynos3250
- Secure firmware for Exynos3250 secondary cpu boot
- Serial ports of Exynos3250
- gpio-key for power key

Recent patch by Tomasz Figa ("irqchip: gic: Fix core ID calculation
when topology is read from DT") fixed GIC driver to filter cluster ID
from values returned by cpu_logical_map() for SoCs having registers
mapped without per-CPU banking making it is possible to add CPU nodes
for Exynos4 SoCs.  In case of Exynos SoCs these CPU nodes are also
required by future changes adding initialization of cpuidle states in
Exynos cpuidle driver through DT.

Tested on Origen board (Exynos4210 SoC) and Trats2 (Exynos4412 SoC).

The MAX77693 is a companion power management IC for smart phones and
tablets.

The MAX77693 contains input over-voltage protection (OVP),
a fully-integrated 2.5A switching charger for Lithium Ion battery with
integrated battery disconnect, OTG/accessory 5V output power,
a high-current white LED driver for camera flash, two safeout LDOs,
a haptic motor driver, Model Gauge m3 battery fuel gauge and MicroUSB
Interface Controller (MUIC). I2C serial interface is used for
communicating.

Add MAX77693 node to the Trats2 board. This allows using:
 - charger regulator,
 - 2 safeout LDO regulators (for USB OTG),
 - extcon.

In MAX77686 PMIC two regulators dedicated for eMMC memory can be
controlled both by I2C interface and a GPIO pin, with the resulting
regulator state being a logical OR of both. Since the GPIO control is
used both by the kernel and the lowest level bootloader at reset, the
regulator should be disabled by I2C control to allow it to be turned off
by GPIO control.

This patch removes regulator-always-on properties from both regulators
and, while at it, also unsupported regulator-mem-off.

Regulators for MMC2 (SD card) are PVDD_TFLASH_2V8 (LDO19) for vmmc

not specified.  Fix it.

Without this patch:
- "mmc: dw_mmc: use mmc_regulator_get_supply to handle regulators"
  patch causes a SD card detection to fail
- "mmc: dw_mmc: Support voltage changes" patch causes a boot hang
