 ## Gpio defs config
-In order to monitor a button/input interface the
-respective gpio config details should be mentioned in the
-gpio defs json file - "/etc/default/obmc/gpio/gpio_defs.json"

 ### Host selector gpio config example
+
 The host selector has four gpios associated. So the related gpios are mentioned
 in a json array named "group_gpio_config".
 
-* name         - This is name of the specific gpio line
-* pin          - This represents the pin number from linux dts file.
-* polarity     - polarity type of the gpio
-* max_position - This represents the max number of hosts in the multi-host
-bmc system.
-* host_selector_map - This map is oem specific host position map which has how the
-value read from the host selector gpios is mapped to the respective host number.
+- name - This is name of the specific gpio line
+- pin - This represents the pin number from linux dts file.
+- polarity - polarity type of the gpio
+- max_position - This represents the max number of hosts in the multi-host bmc
+  system.
+- host_selector_map - This map is oem specific host position map which has how
+  the value read from the host selector gpios is mapped to the respective host
+  number.
 
 Example : The value of "7" derived from the 4 host select gpio lines are mapped
 to host position 1.

 ### Serial uart mux config
-Similar to host selector there are multiple gpios associated with the
-serial uart mux. These gpio configs are specificed as part of json array
- "group_gpio_config".
 
-Here the serial uart mux output is accessed via OCP debug card. SO the OCP
-debug card present gpio is mentioned part of the group_gpio_config. The debug
-card present gpio is identified by its name "debug_card_present".
