| | | | | | | | | | | | | | | | | | | | | bug 1764398 PGSequencer settings use index to writ to PSORDER register setting. HW has implementation for 28 PSORDER (PSORDER0 - 27). Every write will auto increment index and index will wrap around after it reaches 27. In PROD settings we are writing enable for 0 to 27 and zero for 28 to 65. This overwrites enables written to 0 to 27. Effectively those partitions are never power gated.
