Features supported : - the 8 STM32L4x5 GPIOs are initialized with their reset values (except IDR, see below) - input mode : setting a pin in input mode "externally" (using input irqs) results in an out irq (transmitted to SYSCFG) - output mode : setting a bit in ODR sets the corresponding out irq (if this line is configured in output mode) - pull-up, pull-down - push-pull, open-drain Difference with the real GPIOs : - Alternate Function and Analog mode aren't implemented : pins in AF/Analog behave like pins in input mode - floating pins stay at their last value - register IDR reset values differ from the real one : values are coherent with the other registers reset values and the fact that AF/Analog modes aren't implemented - setting I/O output speed isn't supported - locking port bits isn't supported - ADC function isn't supported - GPIOH has 16 pins instead of 2 pins - writing to registers LCKR, AFRL, AFRH and ASCR is ineffective Signed-off-by: Arnaud Minier <arnaud.minier@telecom-paris.fr> Signed-off-by: Inès Varhol <ines.varhol@telecom-paris.fr> Reviewed-by: Philippe Mathieu-Daudé <philmd@linaro.org> Acked-by: Alistair Francis <alistair.francis@wdc.com> Message-id: 20240305210444.310665-2-ines.varhol@telecom-paris.fr Signed-off-by: Peter Maydell <peter.maydell@linaro.org> |
