+Subject: [PATCH] kingfisher: reboot: fix power-off on reset
+
+Method cpld_reset_cpu of bl31 is called from the Linux kernel and uses
+GPIO6, GPIO2 pins as SPI bus lines to control the CPLD device. But in the
+kernel GPIO6_8 pin are initialized to work in interrupt mode instead of
+the input/output mode. This leads to the fact that the SPI bus becomes
+non-functional. In this patch we switch the GPIO6_8 pin back to the
+input-output mode.
