drivers/periph_gpio_ll: Add features for compile-time-checks This adds the features - periph_gpio_ll_input_pull_down: To indicate support for input mode with internal pull down - periph_gpio_ll_input_pull_keep: To indicate support for input mode with internal resistor pulling towards current level - periph_gpio_ll_input_pull_up: To indicate support for input mode with internal pull up - periph_gpio_ll_disconnect: To indicate a GPIO can be disconnected - periph_gpio_ll_open_drain: To indicate support for open drain mode - periph_gpio_ll_open_drain_pull_up: To indicate support for open drain mode with internal pull up - periph_gpio_ll_open_source: To indicate support for open source mode - periph_gpio_ll_open_source_pull_down: To indicate support for open source mode with internal pull down

drivers/periph/gpio_ll: Add API to switch direction This adds two functions: void gpio_ll_switch_dir_output(gpio_port_t port, uword_t outputs); void gpio_ll_switch_dir_input(gpio_port_t port, uword_t inputs); The first configures GPIO pins specified by a bitmask as output, the second configures the specified pins as input. The main use case is to allow bit-banging bidirectional protocols using more basic GPIO peripherals that do not implement open drain mode, such as found e.g. on MSP430, ATmega, or SAM0. It is not intended to implement this feature on modern MCUs with sophisticated GPIO peripherals.
