config MTK_CLKMGR
bool "Mediatek proprietary clock management"
default n
---help---
Mediatek proprietary clock management is used to operate
the clocks. The clocks are composed of CG, MUX, PLL,
non-MTCMOS. The operations of clocks are enabling,
disabling, and querying status. If this config is not set,
system will use COMMON_CLK instead.
config MTK_DISABLE_PICACHU
bool "Disable Picachu"
default n
---help---
PICACHU (PI CAlibration and CHaracterization Utility) aims
at the voltage calibration during booting. It increases
the voltage when needed.
config MTK_DISABLE_SODI
bool "Disable SODI"
---help---
SODI is short for the Screen On Deep Idle.
It's a power saving mode when the screen is still truned on,
but the device always display the same image.
Select if you want to disable it.
config MTK_HYBRID_CPU_DVFS
bool "MediaTek Hybrid CPU DVFS support"
default n
help
This kernel config can be used to control CONFIG_HYBRID_CPU_DVFS
defined/undefined in the header file of CPUHVFS driver.
If CONFIG_HYBRID_CPU_DVFS is defined, CPUHVFS driver will bring up
DVFS processor to do CPU DVFS.
config MTK_SPM_USE_EXT_BUCK
bool "MTK SPM use ext buck"
default n
help
Vmd1 is controlled by an ext buck. If you want to use ext buck for
Vmd1, set y here, or it dependeds on the efuse value.
config MT2701_DCM
bool "Enable MT2701/MT7623 dynamic clock manager"
default y
depends on (MACH_MT2701 || ARCH_MT7623) && MTK_BASE_POWER
---help---
Dynamic Clock Manager(DCM) can help slow bus frequency when
DCM's hardware detects bus is in idle state.
config MTK_CPU_HOTPLUG_DEBUG_0
bool "MediaTek CPU Hotplug DEBUG 0"
default y
help
This kernel config can be used to enable log message in cpu notify
callback function in register_cpu_notifier. This is useful for CPU
hotplug debug.
If unsure, say Y.
config MTK_CPU_HOTPLUG_DEBUG_1
bool "MediaTek CPU Hotplug DEBUG 1"
default n
help
This kernel config can be used to enable log message in cpu notify
callback function in notifier_call_chain. This is useful for CPU
hotplug debug but the performance will be drop down.
If unsure, say N.
config MTK_CPU_HOTPLUG_DEBUG_2
bool "MediaTek CPU Hotplug DEBUG 2"
default y
help
This kernel config can be used to enable aee to log cpu notify
callback in notifier_call_chain. This is useful for CPU hotplug
debug.
If unsure, say Y.
config PROFILE_CPU
bool "Support for CPU hot-plug profiling"
default y
help
This kernel config can be used to enable basic CPU hot-plug
latency for each one. This information is useful for someone who
care the latency, for example, thermal.
If unsure, say Y.
config MTK_CPU_HOTPLUG_DEBUG_3
bool "MediaTek CPU Hotplug DEBUG 3"
default y
help
This kernel config can be used to enable advanced CPU hot-plug
latency profiling. This information is useful for someone who
care the latency, for example, thermal.
If unsure, say Y.
