[PATCH POWERTOP] Remove temporary file created during calibration

[PATCH] Add pinctrl support in powerdebug

by Mohammad Merajul Islam Molla

Add support for pinctrl in powerdebug. Both dump and display modes supported. Tested only on Samsung Arndale board. Sample output in display mode on Arndale Board - Pin Name MUX Owner GPIO Owner HOG Function Group 0 gpa0-0 MUX UNCLAIMED GPIO UNCLAIMED 1 gpa0-1 MUX UNCLAIMED GPIO UNCLAIMED 2 gpa0-2 MUX UNCLAIMED GPIO UNCLAIMED 3 gpa0-3 MUX UNCLAIMED GPIO UNCLAIMED 4 gpa0-4 MUX UNCLAIMED GPIO UNCLAIMED 5 gpa0-5 MUX UNCLAIMED GPIO UNCLAIMED 6 gpa0-6 12c80000.i2c GPIO UNCLAIMED i2c2-bus-mux i2c2-bus-grp 7 gpa0-7 12c80000.i2c GPIO UNCLAIMED i2c2-bus-mux i2c2-bus-grp 8 gpa1-0 MUX UNCLAIMED GPIO UNCLAIMED 9 gpa1-1 MUX UNCLAIMED GPIO UNCLAIMED 10 gpa1-2 12c90000.i2c GPIO UNCLAIMED i2c3-bus-mux i2c3-bus-grp 11 gpa1-3 12c90000.i2c GPIO UNCLAIMED i2c3-bus-mux i2c3-bus-grp --- Android.mk | 2 +- Makefile | 2 +- README | 4 +- display.c | 3 +- display.h | 2 +- pinctrl.c | 329 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ pinctrl.h | 19 ++++ powerdebug.c | 35 +++++-- 8 files changed, 381 insertions(+), 15 deletions(-) create mode 100644 pinctrl.c create mode 100644 pinctrl.h diff --git a/Android.mk b/Android.mk index 36c73cd..19d00ca 100644 --- a/Android.mk +++ b/Android.mk @@ -29,6 +29,6 @@ LOCAL_C_INCLUDES += external/stlport/stlport/ \ LOCAL_SRC_FILES += \ powerdebug.c sensor.c clocks.c regulator.c \ - display.c tree.c utils.c mainloop.c gpio.c + display.c tree.c utils.c mainloop.c gpio.c pinctrl.c include $(BUILD_EXECUTABLE) diff --git a/Makefile b/Makefile index 2da9d67..f002438 100644 --- a/Makefile +++ b/Makefile @@ -5,7 +5,7 @@ CFLAGS?=-O1 -g -Wall -Wshadow CC?=gcc OBJS = powerdebug.o sensor.o clocks.o regulator.o gpio.o \ - display.o tree.o utils.o mainloop.o + display.o tree.o utils.o mainloop.o pinctrl.o default: powerdebug diff --git a/README b/README index 1479db1..b24dd98 100644 --- a/README +++ b/README @@ -1,8 +1,8 @@ powerdebug ---------- -This is a new tool which displays regulator, sensor and clock tree -information. +This is a new tool which displays regulator, sensor, clock tree, gpio and +pinctrl information.

[PATCH] pm-qa/cpuhotplug: Enable cpuhotplug on cpu0

Pass hotplug_cpu_start=0 to make check like these examples below: sudo make -C cpuhotplug hotplug_cpu_start=0 check sudo make hotplug_cpu_start=0 check to enable cpuhotplug to run on cpu0 to N. The hotplug_cpu_start variable will take the default value of 1 if no value is passed so cpuhotplug will run on cpu1 to N.
