Summary
GPIO peripheral clocks have to be enabled even if interrupt support on the peripheral is not enabled, otherwise GPIO input will not work. This is probably caused by input filters that need clock signal.
This commit moves the clock enable call from interrupt specific function to common initialization function that is called from
_startentry point function.Impact
GPIO inputs now work even if the peripheral is not configured with interrupt support (option
CONFIG_SAMV7_GPIOx_IRQ).Testing
Tested on custom SAMv7 board with GPIOD peripheral. Reading pins now work even if
CONFIG_SAMV7_GPIOD_IRQis disabled.
