From 52835d59fc6cc7f3c3cfdb4a194ddc9ebd6c0c31 Mon Sep 17 00:00:00 2001 From: Dave Gerlach Date: Tue, 4 Apr 2017 08:59:27 -0700 Subject: soc: ti: Add ti_sci_pm_domains driver Introduce a ti_sci_pm_domains driver to act as a generic pm domain provider to allow each device to attach and associate it's ti-sci-id so that it can be controlled through the TI SCI protocol. This driver implements a simple genpd where each device node has a phandle to the power domain node and also must provide an index which represents the ID to be passed with TI SCI representing the device using a single phandle cell. The driver manually parses the phandle to get the cell value. Through this interface the genpd dev_ops start and stop hooks will use TI SCI to turn on and off each device as determined by pm_runtime usage.
