• aa12c1ab8   spi: jcore: Fix module autoload for OF registration ... Browse Code »

  If the driver is built as a module, autoload won't work because the module
  alias information is not filled. So user-space can't match the registered
  device with the corresponding module.

  Export the module alias information using the MODULE_DEVICE_TABLE() macro.

  Before this patch:

  $ modinfo drivers/spi/spi-jcore.ko | grep alias
  alias: platform:jcore_spi

  After this patch:

  $ modinfo drivers/spi/spi-jcore.ko | grep alias
  alias: platform:jcore_spi
  alias: of:N*T*Cjcore,spi2C*
  alias: of:N*T*Cjcore,spi2

• f75529fd7   spi: jcore: remove unnecessary platform_set_drvdata() ... Browse Code »

  The driver core clears the driver data to NULL after device_release
  or on probe failure. Thus, it is not needed to manually clear the
  device driver data to NULL.

• 2cb1b3b3a   spi: add driver for J-Core SPI controller ... Browse Code »

  The J-Core "spi2" device is a PIO-based SPI master controller. It
  differs from "bitbang" devices in that that it's clocked in hardware
  rather than via soft clock modulation over gpio, and performs
  byte-at-a-time transfers between the cpu and SPI controller.

  This driver will be extended to support future versions of the J-Core
  SPI controller with DMA transfers when they become available.
