Hi Mark, > The goal is just to connect a GPIO (and GPIO controlled by any GPIO > controller) to the chip select of the device and make sure that the chip select output of the controller isn't routed anywhere where it'll do any harm. If you have an existing board where spi-dw native chip-select has been used instead of other independent gpios, than you can't use "gpio-cs" to re-own & control those chip-select, and has a potential tx-transaction-split problem that must be solved via the attached software patch.
