This condition can only be resolved through JTAG and advancing beyond the while loop in a8_lp_ds0_handler [1]. Although this hangs the system it forces the system to remain active once it has been entirely configured for low power mode entry, allowing for register inspection through JTAG to help in debugging transition errors. Halt mode can be set using the enable_off_mode entry under wkup_m3_ipc in the debugfs.

Proper binary format is determined by the FW in use. Code expects firmware to have 0x0C57 present as the first two bytes followed by one byte defining offset to sleep sequence followed by one byte defining offset to wake sequence and then lastly both sequences. Each sequence is a series of I2C transfers in the form: u8 length | u8 chip address | u8 byte0/reg address | u8 byte1 | u8 byteN .. The length indicates the number of bytes to transfer, including the register address. The length of each transfer is limited by the I2C buffer size of 32 bytes. Based on previous work by Russ Dill.

The actual toggling happens from the wkup_m3, so use a DT property from the wkup_m3_ipc node to allow the PM code to communicate the necessity for placing the IOs into isolation to the firmware.
