config UX500_CPUFREQ
tristate "CPUFreq support"
depends on (UX500_SOC_DB8500 || UX500_SOC_DB5500) && CPU_FREQ && PM
default y
help
Add support for CPU Frequency scaling for Ux500 SOCs.
ARM power domains operating points can be set
dynamically. It depends on CPUfreq and PM subsystem.
config U8500_CPUIDLE
tristate "CPUIdle support"
depends on (UX500_SOC_DB8500 || UX500_SOC_DB5500) && CPU_IDLE && !RTC_DRV_PL031 && PM
default y
select GENERIC_CLOCKEVENTS_BROADCAST
select UX500_CONTEXT
help
Add support for CPUIdle for U8500.
config U8500_CPUIDLE_DEEPEST_STATE
int "Deepest sleep state"
default 4 if UX500_SOC_DB8500
default 1 if UX500_SOC_DB5500
depends on U8500_CPUIDLE
help
Set deepest sleep state. See the cstate struct in cpuidle.c.
Default is ApSleep.
config U8500_CPUIDLE_APDEEPIDLE
bool "CPUIdle ApDeepIdle"
depends on U8500_CPUIDLE
help
Adds the power level ApDeepIdle, where APE is powered on while
ARM is powered off. Default n.
config U8500_CPUIDLE_DEBUG
bool "CPUIdle debug"
depends on U8500_CPUIDLE && DEBUG_FS
help
Add debugging support for CPUIdle for U8500.
config UX500_SUSPEND
bool "Suspend to mem and standby support"
depends on (UX500_SOC_DB8500 || UX500_SOC_DB5500) && PM
select UX500_CONTEXT
help
Add support for suspend.
config UX500_SUSPEND_STANDBY
bool "Suspend Standby goes to ApSleep"
depends on UX500_SUSPEND
help
If yes, echo standby > /sys/power/state puts the system into ApSleep.
config UX500_SUSPEND_MEM
bool "Suspend Mem goes to ApDeepSleep"
depends on UX500_SUSPEND && UX500_SOC_DB8500
help
If yes, echo mem > /sys/power/state puts the system into ApDeepSleep else
it will do the same as echo standby > /sys/power/state.
config UX500_SUSPEND_DBG
bool "Suspend debug"
depends on UX500_SUSPEND && DEBUG_FS
help
Add debug support for suspend.
config UX500_SUSPEND_DBG_WAKE_ON_UART
bool "Suspend wakes on console UART"
depends on UX500_SUSPEND_DBG
help
Wake up on uart interrupts. Makes it possible for the console to wake up system.
config UX500_CONSOLE_UART_GPIO_PIN
int "The pin number of the console UART GPIO pin"
default 29
depends on UX500_SUSPEND_DBG_WAKE_ON_UART || U8500_CPUIDLE_DEBUG
help
GPIO pin number of the GPIO pin connected to the console UART RX line.
config UX500_CONTEXT
bool "Context save/restore support for UX500"
depends on (UX500_SOC_DB8500 || UX500_SOC_DB5500) && PM
help
This is needed for ApSleep and deeper sleep states.
