The ODROID kernel shows that the PMIC interrupt line is hooked up
to pin GPX3-2.
This is needed for the max77686-irq driver to create the PMIC IRQ
domain, which is needed by max77686-rtc.

Increase max i2c bus frequency beyond the default for faster
data transfers. According to the manual, these faster speeds are
only available when the board is wired up the right way. In this case,
the vendor kernel has run at this speed for a long time.
sda-delay is needed for talking to RTC on PMIC, otherwise the i2c
controller never sees an ACK. Strangely the other PMIC i2c slave (the
main one) works fine even without this delay. I Chose value 100 to
match the vendor kernel.

Unfortunately these patches were applied to v3.18-next/dt-samsung
branch and not v3.17-samsung-fixes-1 one.
IMHO they should go to upstream ASAP as they fix the boot for
ODROID boards and they cannot break anything as they are limited
to ODROID dts files.

Hi,
I'm about to send a batch up to Linus, and this was quick to apply
myself, so I've done so -- I'm interested in keeping this hardware
working since I have it in my test setup as the only EXYNOS4 machine.
