From: Axel Haslam <ahaslam+renesas@baylibre.com>
Some architectures may have intermediate power levels between on and off.
This patch set adds the ability to declare multiple states for a given generic power domain, the idea is that the deepest state will be entered which does not violate any of the device or sub-domain latency constraints.
Changes since v9 *rebased on linux-next
Changes since v8 * rebased to linux-pm next
Changes since v7: * rebase to 4.3-rc5
* add genpd_init_simple (Lina's suggestion) for platforms that don't have multiple states and don't declare initial latencies. A default OFF state with initial 0 latencies will be used in this case.
* Append Mark's patch to add "states" and "timings" to the genpd debugfs
Changes since v6: * change int to unsigned int were appropriate.
* spelling mistakes, and fix commit message for removal of latencies.
Changes since v5: * rebase to 4.1-rc1
* Pass state array as an init argument on pm_genpd_init
* declare a default OFF state with no latencies, that will be used if a null state argument is given.
* set the deepest state when using sync_poweroff.
* create and use name allocation function in the debug area instead of inline.
Changes since v4: * move to power_on/off callbacks out of the state array Platforms can check the state_idx to know what state the power on/off corresponds to.
* convert states to pointer, Dynamically allocate the states array to save memory on platforms with several power domains.
* rename target_state to state_idx and remove init_state.
Changes since v3: * remove old power on/off function at the end of the series so that compilation will not break in between.
Changes since v2: * remove state argument and macros from save/restore callbacks.
* added init_state for platforms to pass the initial state when the genpd is initially off.
* convert current genpd users for the structure changes.
Changes since v1: * split the changes so that the actual logic that selects the target state is a separate patch.
* move the cached logic out of the state function and add it back to default_power_down_ok.
* rename default_power_down_ok_state to power_down_ok_for_state
Axel Haslam (5): PM / Domains: prepare for multiple states PM / Domains: core changes for multiple states PM / Domains: make governor select deepest state ARM: imx6: pm: declare pm domain latency on power_state struct. PM / Domains: remove old power on/off latencies.
Marc Titinger (1): PM / Domains: add debugfs 'states' and 'timings' seq files
