14 The TI AM33xx and AM43xx family of devices use a small Cortex M3 co-processor
17 C-states for CPU Idle. Once the wkup_m3_ipc driver uses the wkup_m3_rproc driver
20 API to allow the SoC PM code to execute specific PM tasks.
29 On some boards like the AM335x EVM-SK and the AM437x GP EVM, a GPIO pin is

137 * On the AM437x-GP-EVM board, gpio5_7 is wired to enable pin of the DDR VTT
139 * for pull-up during normal system operation. However, the DS0 (deep sleep)
140 * state of the pin is configured for pull-down and thus the VTT regulator
142 * this method is an alternative to using the 'ti,vtt-gpio-pin' property.
