Thread:Talk:BeagleBone Black Enable SPIDEV/Clock pins direction

AFAIK, Linux supports SPI in master mode only. In other words, it drives the clock signal. So, shouldn't the clock pins be outputs? For example:

0x190 0x33     /* mcasp0_aclkx.spi1_sclk, OUTPUT_PULLUP | MODE3 */

0x150 0x30 /* spi0_sclk, OUTPUT_PULLUP | MODE0 */
