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
