/* LED force ctrl is the same for every LED
 * No documentation exist for this, not even internal one
 * with NDA as QCOM gives only info about configuring
 * hw control pattern rules and doesn't indicate any way
 * to force the LED to specific mode.
 * These define comes from reverse and testing and maybe
 * lack of some info or some info are not entirely correct.
 * For the basic LED control and hw control these finding
 * are enough to support LED control in all the required APIs.
 *
 * On doing some comparison with implementation with qca807x,
 * it was found that it's 1:1 equal to it and confirms all the
 * reverse done. It was also found further specification with the
 * force mode and the blink modes.
