Subject: [PATCH] trace-debug[stm]: Fix for BT/WLAN instability
|
|
|
|
Pins under mop500_ske_pins array are used for different
|
|
functionalities in snowball. Ex: GPIO161 pin configured
|
|
for keypad here must stay configured as GPIO alternate
|
|
function for operating PMU_EN pin of BT/WLAN chip in snowball.
|
|
So forbid configuring these pins, for snowball
