From c84e358718a66f76ac0de1681d15d8d0c68fcdab Mon Sep 17 00:00:00 2001 From: Sascha Hauer Date: Wed, 24 Jun 2015 08:17:04 +0200 Subject: soc: Mediatek: Add SCPSYS power domain driver This adds a power domain driver for the Mediatek SCPSYS unit. The System Control Processor System (SCPSYS) has several power management related tasks in the system. The tasks include thermal measurement, dynamic voltage frequency scaling (DVFS), interrupt filter and lowlevel sleep control. The System Power Manager (SPM) inside the SCPSYS is for the MTCMOS power domain control. For now this driver only adds power domain support, the more advanced features are not yet supported. The driver implements the generic PM domain device tree bindings, the first user will most likely be the Mediatek AFE audio driver.
