58 * Flags to control the behaviour of a genpd.
59 *
60 * These flags may be set in the struct generic_pm_domain's flags field by a
61 * genpd backend driver. The flags must be set before it calls pm_genpd_init(),
62 * which initializes a genpd.
63 *
64 * GENPD_FLAG_PM_CLK: Instructs genpd to use the PM clk framework,
65 * while powering on/off attached devices.
66 *
67 * GENPD_FLAG_IRQ_SAFE: This informs genpd that its backend callbacks,
68 * ->power_on|off(), doesn't sleep. Hence, these
69 * can be invoked from within atomic context, which
70 * enables genpd to power on/off the PM domain,
71 * even when pm_runtime_is_irq_safe() returns true,
72 * for any of its attached devices. Note that, a
73 * genpd having this flag set, requires its
74 * masterdomains to also have it set.
75 *
76 * GENPD_FLAG_ALWAYS_ON: Instructs genpd to always keep the PM domain
77 * powered on.
78 *
79 * GENPD_FLAG_ACTIVE_WAKEUP: Instructs genpd to keep the PM domain powered
80 * on, in case any of its attached devices is used
81 * in the wakeup path to serve system wakeups.
82 *
83 * GENPD_FLAG_CPU_DOMAIN: Instructs genpd that it should expect to get
84 * devices attached, which may belong to CPUs or
85 * possibly have subdomains with CPUs attached.
86 * This flag enables the genpd backend driver to
87 * deploy idle power management support for CPUs
88 * and groups of CPUs. Note that, the backend
89 * driver must then comply with the so called,
90 * last-man-standing algorithm, for the CPUs in the
91 * PM domain.
92 *
93 * GENPD_FLAG_RPM_ALWAYS_ON: Instructs genpd to always keep the PM domain
94 * powered on except for system suspend.
95 *
96 * GENPD_FLAG_MIN_RESIDENCY: Enable the genpd governor to consider its
97 * components' next wakeup when determining the
98 * optimal idle state.
99 *
100 * GENPD_FLAG_OPP_TABLE_FW: The genpd provider supports performance states,
101 * but its corresponding OPP tables are not
102 * described in DT, but are given directly by FW.
103 *
104 * GENPD_FLAG_DEV_NAME_FW: Instructs genpd to generate an unique device name
105 * using ida. It is used by genpd providers which
106 * get their genpd-names directly from FW.
