thierry, this is the reference pinouts of the panel http://www.tonylabs.com/wp-content/uploads/LT070ME05000-pinouts.jpg as you suggest , i will change the vcc-supply, - iovcc-supply: phandle of the regulator that supplies power to the IOVCC voltage input (1.8 V) will keep the other two(vddp-supply, dcdc_en-supply) remaining same.
