The regulator core now has support to choose if a regulator
has to be enabled or disabled during system suspend and also
supports changing the regulator operating mode during runtime
and when the system enters into sleep mode.
To lower power during suspend, configure the regulators state
using the same configuration found in the ChromeOS 3.8 kernel

The Exynos5420 Peach Pit and Exynos5800 Peach Pi boards have a built-in
Silicon Motion USB UVC WebCam whose power supply is the tps65090 fet5
regulator. Since the camera uses the generic USB Video Class driver and
this does not grab a regulator, mark the regulator as always on so the
USB device is enumerated and usable.

commit 546b117fdf17 ("rtc: s3c: add support for RTC of Exynos3250 SoC")
added an "rtc_src" DT property for the Samsung's S3C Real Time Clock
controller that specifies the 32.768 kHz clock that uses the RTC as
its source clock. In the case of the Peach Pit and Pi machines, the
Maxim 77802 32kHz AP clock is used as the source clock.

In case the optional dr_mode property isn't set in the dwc3 nodes the
the controller will go into OTG mode if both USB host and USB gadget
functionality are enabled in the kernel configuration. Unfortunately
this results in USB not working on exynos5420-peach-pit and
exynos5800-peach-pi with such a kernel configuration unless manually
change the mode. To resolve that explicitly configure the dual role
mode as host.

The DeviceTree files for the Peach Pit and Pi machines have
a simplistic model of the connections between the different
regulators since not all the tps65090 regulators get their
input supply voltage from the VDC. DCDC1-3, LD0-1 and fet7
parent supply is indded VDC but the fet1-6 get their input
supply from the DCDC1 and DCDC2 output voltage rails.
Update the DeviceTree to better reflect the real connections
between tps65090 regulators. Having this information in the
DTS is useful since FETs are switches that don't provide an
output voltage so the regulator core needs to fetch the FET
parent output voltage if the child voltage is queried.

The mask-tpm-reset GPIO is used by the kernel to prevent the TPM from
being reset across sleep/wake. If we don't set it to anything then
the TPM will be reset. U-Boot will detect this as invalid
and will reset the system on resume time. This GPIO can always be low
and not hurt anything. It will get pulled back high again during a
normal warm reset when it will default back to an input.
To properly preserve the TPM state across suspend/resume and to make
the chrome U-Boot happy, properly set the GPIO to mask the
reset to the TPM.
