+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
