Marian Buschsieweke 2a00ec13e5 drivers/periph/gpio_ll: shrink gpio_conf_t ... This commit optimizes the `gpio_conf_t` type in the following regards: - The "base" `gpio_conf_t` is stripped from members that only some platforms support, e.g. drive strength, slew rate, and disabling of the Schmitt Trigger are no longer universally available but platform-specific extensions - The `gpio_conf_t` is now crammed into a bit-field that is 8 bit or 16 bit wide. This allows for storing lots of them e.g. in `driver_foo_params_t` or `uart_conf_t` etc. - A `union` of the `struct` with bit-field members and a `bits` is used to allow accessing all bits in a simple C statement and to ensure alignment for efficient handling of the type Co-authored-by: Gunar Schorcht <gunar@schorcht.net>		2024-01-21 08:38:40 +01:00
