How to enable MMC3 interface?

$

Our processor is DRA746(with PMIC TPS-659039), with 3.02.00.03 SDK version

We connect MMC3 interface (only connect cmd, clk, 4 data pins) with micro-SD card at our custom board. Since there is no &mmc3 node at dra7-evm.dts, so we add it(but the content almost the same as &mmc1, except pin define)

Now, the system can't detect micro-SD card after boot up. The log show below messages:

omap_hsmmc 480ad000.mmc: vmmc_aux set voltage failed
omap_hsmmc 480ad000.mmc: failed to switch 1.8v

The full boot log info => (Please visit the site to view this file)   

Our dts file => (Please visit the site to view this file)   

Any suggestion for further debug?

Regards,

Shawn
