It really needs to look like this:

pwmleds {
	compatible = "pwm-leds";
	kpad {
		label = "omap4::keypad";
		max-brightness = <127>;
		pwms = <&twl_pwm 0 7812500>;
	};
	charging {
		label = "omap4:green:chrg";
		max-brightness = <255>;
		pwms = <&twl_pwmled 0 7812500>;
	};
};

OK.
So What we need to do is export the of_pwm_request() from drivers/pwm/core.c
Client drivers us of_pwm_request(node, NULL); to get the pwm when booted with DT.
Works fine on my setup this way and the DTS section looks just as you have
described.
Now I need to clean them up and resubmit.

Cool, thanks.
