[PATCH 7/8] ir-rx51: Remove MPU wakeup latency adjustments

2012-08-22 Thread Timo Kokkonen
The ir-rx51 driver calls omap_pm_set_max_mpu_wakeup_lat() in order to avoid problems that occur when MPU goes to sleep in the middle of sending an IR code. Without such calls it takes ridiculously long for the MPU to wake up from a sleep, which distorts the IR signal completely. However, the actua
