MTK gpio adb 控制 和 查看中断INDEX

cd /sys/class/misc/mtgpio/                                    
tpw8735b_t3h:/sys/class/misc/mtgpio # ls
dev pin power single_pin subsystem uevent
tpw8735b_t3h:/sys/class/misc/mtgpio # cat pin | grep 60                        
 60:01111110
160:10000110
cho -wdout 60 0 > pin                                                         <
tpw8735b_t3h:/sys/class/misc/mtgpio # cat pin | grep 60                        
 60:01001110
160:10000110
tpw8735b_t3h:/sys/class/misc/mtgpio # echo -wdout 60 1 > pin                   
tpw8735b_t3h:/sys/class/misc/mtgpio # echo -wdout 60 0 > pin                   
tpw8735b_t3h:/sys/class/misc/mtgpio # echo -wdout 59 0 > pin                   
tpw8735b_t3h:/sys/class/misc/mtgpio # echo -wdout 59 1 > pin

cat  /proc/interrupts 确定下中断的index

另一种情况 

adb shell 

cd sys

find . -name mt_gpio 会找到 这样类似的pin 

 sys/devices/platform/1000b000.pinctrl/mt_gpio

cat  sys/devices/platform/1000b000.pinctrl/mt_gpio 会有 GPIO 口出现

直接echo out pin脚号 0/1 > sys/devices/platform/1000b000.pinctrl/mt_gpio 即可
