If anyone has any objections, please let me know. ------------------ From: Cosmo Chou [ Upstream commit 65a38a28a0b04af19a5e1fbf3869051412eeac96 ] The pca9532_gpio_set_value() function incorrectly mapped the requested value to PCA9532_ON and PCA9532_OFF, inverting the GPIO output polarity. A requested logical high (val=1) incorrectly enabled the LED output driver, which on this open-drain device pulls the pin low, while a requested logical low (val=0) released the pin. Correct the mapping so that val=1 yields PCA9532_OFF (pin released / high-impedance) and val=0 yields PCA9532_ON (pin driven low). pca9532_gpio_direction_input() is also updated to pass val=1 to pca9532_gpio_set_value() to align with the corrected polarity mapping, ensuring the pin remains not driven when configured as an input.
