disable spi chipselect in runtime #31779

Open teijokk opened 3 years ago

teijokk commented 3 years ago

We need to swich power off spi slave when not used. This causes slave cs pin go ground while host cpu cs is high(because cs is active low) This causes power consumption.

We are currently not found a way to disable or set cs low. Is this possible to do in zephyr?
