From a5ea7a0fcbd7376b2c9fcb15fe59fec298c9ce9f Mon Sep 17 00:00:00 2001 From: Dave Gerlach Date: Tue, 4 Apr 2017 08:51:29 -0700 Subject: PM / Domains: Add generic data pointer to genpd data struct Add a void *data pointer to struct generic_pm_domain_data. Because this exists for each device associated with a genpd it will allow us to assign per-device data if needed on a platform for control of that specific device.

Currently the genpd framework will fail if any arguments are passed with for a simple provider but the framework does not actually care, so remove the check for phandle argument count. This will allow greater flexibility for genpd providers to use their own arguments that are passed in the phandle and interpret them however they see fit.

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.
