The return prevents the power domains from getting registered.
Hence removing it to allow the frameworks model to work.

I don't have an OMAP4 with me, but I found something weird in your reported behaviour...

The code that was being skipped is:

	/*
	 * OK, now we know the exact revision. Initialize omap_chip bits
	 * for powerdowmain and clockdomain code.
	 */
	if (cpu_is_omap243x()) {
		/* Currently only supports 2430ES2.1 and 2430-all */
		omap_chip.oc |= CHIP_IS_OMAP2430;
	} else if (cpu_is_omap242x()) {
		/* Currently only supports 2420ES2.1.1 and 2420-all */
		omap_chip.oc |= CHIP_IS_OMAP2420;
	} else if (cpu_is_omap3505() || cpu_is_omap3517()) {
		omap_chip.oc = CHIP_IS_OMAP3430 | CHIP_IS_OMAP3430ES3_1;
	} else if (cpu_is_omap343x()) {
		omap_chip.oc = CHIP_IS_OMAP3430;
		if (omap_rev() == OMAP3430_REV_ES1_0)
			omap_chip.oc |= CHIP_IS_OMAP3430ES1;
		else if (omap_rev() >= OMAP3430_REV_ES2_0 &&
			 omap_rev() <= OMAP3430_REV_ES2_1)
			omap_chip.oc |= CHIP_IS_OMAP3430ES2;
		else if (omap_rev() == OMAP3430_REV_ES3_0)
			omap_chip.oc |= CHIP_IS_OMAP3430ES3_0;
		else if (omap_rev() == OMAP3430_REV_ES3_1)
			omap_chip.oc |= CHIP_IS_OMAP3430ES3_1;
		else if (omap_rev() == OMAP3630_REV_ES1_0)
			omap_chip.oc |= CHIP_IS_OMAP3630ES1;
	} else {
		pr_err("Uninitialized omap_chip, please fix!\n");
	}

And, in theory, in OMAP4 case, you SHOULDN'T be doing anything here, as there's no case for cpu_is_omap443x or similar. So you should be _only_ seeing a print in console saying: "Uninitialized omap_chip, please fix!", right?

Is OMAP4 chip giving positive on cpu_is_omap343x() test then??

Sergio

Sergio,
	I have taken care of that in my other patches, which I had posted earlier. They are not in mainline yet but are lined up for the next release. You can find the same here.

http://marc.info/?l=linux-omap&m=126088474831309&w=2

Do let me know if you have any further questions.

Best Regards,
Abhijit Pagare
