The board uses 26MHz oscillator for the twl4030 HFCLK.
This way we will not depend on the bootloader to configure the
CFG_BOOT:HFCLK_FREQ

Hi,
there might be other boards (all omap3 boards with twl4030?) which uses the same
setup, but I only have schematics for beagle-xm.
In order for the driver to actually use the clock the
[PATCH] mfd: twl-core: Fix clock initialization
need to be applied. W/o the twl-core patch the clock is just ignored.
Regards,
Peter
