Hi, This is v2 of the series to add support for TI SCI PM Domains. v1 of the series can be found here [1]. Several things have changed since v1: - New patch to add a void *data to struct generic_pm_domain_data to allow to store per device data associated with a genpd - From v1, squash patch 1 and 2 to introduce docs and dt-bindings in one patch based on comment from Ulf - Fix some grammar errors in Documentation - Based on comments from Ulf, rework actual genpd implementation to avoid creating one genpd per device and instead use device start/stop hooks provided as part of genpd to control device state based on pm_runtime implementation. Also make use of new of_genpd_add_provider_simple API introduced by Jon Hunter and do not provide custom of_xlate to genpd core, instead registering devices as they probe through attach_dev hook provided by genpd framework. Most of the changes were motivated by the comments from Ulf Hannson on v1 that we should not use a 1-to-1 genpd to device mapping. The new approach allows us to create a single genpd and store information about each device as they attach to the genpd. Then the device start/stop hooks for that genpd leverage the per-device data to control power states over the TI SCI protocol. This driver makes use of the ti_sci driver sent here [2] by Nishanth Menon and applies on top of his series on v4.9-rc1.
