Currently, omap4 keypad mux settings are done in the board file.
Populate the mux settings in the dts file for the keypad to
work via dt.

Tested on omap4430 sdp with 3.7-rc1.

Have you changed the driver to handle properly the dependency with the
pinctrl and thus return EPROBE_DEFER if this is not ready?

Seb Guiriec has just sent a patch to do that for the omap-i2c driver
([PATCH] i2c: omap: adopt pinctrl support).

Alway use lower case for hexa value.

Otherwise that looks good.

I have send a patch[1] to the mailing list on the driver changes.
http://www.spinics.net/lists/linux-omap/msg79985.html.

Though, I see I have missed the following EPROBE_DEFER check..
+               if (PTR_ERR(dev->pins) == -EPROBE_DEFER)
+                       return -EPROBE_DEFER;
Will add for the above patch.

Yeah, sorry, I've just seen it :-(.

Yes, indeed.

Please shorten these to leave out OMAP_:

		pinctrl-single,pins = <
			0x24 0x4119   /* gpmc_a18.kpd_row6 PULL_ENA | PULL_UP | WAKEUP_EN | MUX_MODE1 | INPUT_EN */
			0x26 0x4119   /* gpmc_a19.kpd_row6 PULL_ENA | PULL_UP | WAKEUP_EN | MUX_MODE1 | INPUT_EN */
			...

When we convert them over to use the preprocessor, we can still
easily replace them.

Regards,

Tony
