linux-toradex.git/include/linux/amba/pl022.h, branch tegra-9.12.15 Linux kernel for Apalis and Colibri modules ARM: 5678/1: SSP/SPI PL022 polarity terminology fix 2009-09-18T21:09:02+00:00 Linus Walleij linus.walleij@stericsson.com 2009-08-15T14:12:05+00:00 ee2b805c8eb6459cf541ef141ff70dae17af59ca The definition of the SPI clock phase for the Motorola mode of the PL022 driver was incorrect: the spec had been interpreted as data being recieved on rising or falling edge of the clocks while the correct interpretation is that data can be recieved on the first or second edge transition, falling or rising depending on the polarity setting.
