26 * @brief Does a SPI controller node have chip select GPIOs configured?
28 * SPI bus controllers use the "cs-gpios" property for configuring
29 * chip select GPIOs. Its value is a phandle-array which specifies the

50 * @return 1 if "spi" has a cs-gpios property, 0 otherwise
55 * @brief Number of chip select GPIOs in a SPI controller's cs-gpios property
