Allow pin modes OpenDrain and PushPull for SPI output pins #226

Closed osannolik closed 1 year ago

osannolik commented 1 year ago

I needed to use OpenDrain mode for SPI output pins, but the init for SPI were only defined for pins set to Analog (i.e. implicitly PushPull). Therefore I added Output<OpenDrain> as an alternative and also Output<PushPull> to allow for more explicit user peripheral setup code.
