[PATCH v1 05/10] ARM: dts: exynos: Add rtc clock definitions for MAX77686 PMIC for Exynos4412 p4note

[Anand Moon <linux.amoon@gmail.com>]

The MAX77686A includes a crystal driver with an external load capacitance.
When enabled, the crystal driver starts in low power mode. The
LowJitterMode bit controls the crystal driver, allowing it to switch
between low power mode and low jitter mode (high power mode).
Setting the LowJitterMode bit to 1 activates low jitter mode on
three channels simultaneously. These three 32khz buffer outputs
(32KHAP, 32KHCP, P32KH) are independently enabled/disabled over I2C.

The 32khz_ap output is typically routed to the AP Processor, while the
32khz_cp and 32khz_pmic outputs are intended for BT, WLAN, BB,
or peripheral chipsets.
