This patch supports the TPS65910 PMU function on the AM3517 Craneboard.
The IRQ pin, SYS_NIRQ is dedicated connection between the AM3517 and
the TPS65910 PMU.
To handle the PMU IRQs, mux configuration is required.
Platform data configuration:
.IRQ number : SYS_NIRQ (M_IRQ_7)
.External clock source : external 32KHz clock is connected

Thanks applying 1 and 2 into omap-for-v3.9/board. Did not
see patch 3 of this anywhere?
Anyways, let's plan on making this work with device tree and
keep the changes to the board-*.c files to minimum.
Regards,
Tony

Thank you.
The third patch is for the TPS65910 PMU on the Craneboard.
It was already applied.
