If anyone has any objections, please let me know. ------------------ From: Michal Vokáč commit 8512fbb64b0e599412da661412d10d4ba1cb003c upstream. On the imx6dl-yapp4 revision based boards, the RGB LED is not driven directly by the LP5562 driver but through FET transistors. Hence the LED current is not determined by the driver but by the LED series resistors. On the imx6dl-yapp43 revision based boards, we removed the FET transistors to drive the LED directly from the LP5562 but forgot to tune the output current to match the previous HW design. Set the LED current on imx6dl-yapp43 based boards to the same values measured on the imx6dl-yapp4 boards and limit the maximum current to 20mA.
