linux-toradex.git/include/linux/amba/pl022.h, branch tegra-10.11.7 Linux kernel for Apalis and Colibri modules spi/pl022: add support for the PL023 derivate 2010-05-25T06:23:14+00:00 Linus Walleij linus.walleij@stericsson.com 2010-05-07T08:40:53+00:00 781c7b129b1beb876905f7212927aa0ee1b022e5 This adds support for a further ST variant of the PL022 called PL023. Some differences in the control registers due to being stripped down to SPI mode only, and a new clock feedback sample delay config setting is available.

spi/pl022: fix up differences between ARM and ST versions 2010-05-25T06:23:13+00:00 Linus Walleij linus.walleij@stericsson.com 2010-05-05T09:28:15+00:00 556f4aeb7d9dfac8573d0281dd555bd3210d8366 The PL022 SPI driver did not cleanly separate between the original unmodified ARM version and the ST Microelectronics versions. Split this more cleanly and fix some whitespace moaning from checkpatch at the same time.

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.
