298 * FreeCalypso change: in TI's original code, whenever
299 * this Cust_check_system() function returns FRAME_STOP
300 * instead of CLOCK_STOP, l1s_sleep_manager() would
301 * abstain from all sleep and not just from deep sleep.
302 * The comments there say that the intent is to avoid
303 * big sleep when there is UART or SIM activity,
304 * but the result is that when we tell L1 to do big sleep
305 * instead of deep sleep because of the backlight or
306 * charging, it doesn't sleep at all, except small sleep
307 * via Nucleus idle loop.
308 *
309 * Our change preserves TI's abstention from big sleep
310 * due to UART or SIM activity, but allows big sleep when
311 * the cause is light or charging. We've changed this
312 * Cust_check_system() function to return DO_NOT_SLEEP
313 * instead of FRAME_STOP for UART and SIM, while still
314 * returning FRAME_STOP for light and charging, and
315 * changed the code in l1s_sleep_manager() to do big sleep
316 * when this Cust_check_system() function returns FRAME_STOP.
