  Platform data pointer may be NULL. We check it everywhere but in one
  place. Fix it.

• 8af70cd2c   memory: aemif: add support for board files ... Browse Code »

  Currently aemif is supported in two places separately. By the platform
  driver in drivers/memory and by a hand crafted driver in mach-davinci.

  We want to drop the latter but also keep the legacy mode. Add support
  for board files to the aemif driver.

  The new structure in platform data currently only contains the chip
  select number, since currently existing users don't require anything
  else, but it can be extended in the future.

  While extending the platform data struct, add kernel docs describing
  its members.

  We want to use aemif from board files. Use a static name in the
  driver's code.

• f95bd0412   memory: aemif: allow passing device lookup table as platform data ... Browse Code »

  TI aemif driver creates its own subnodes of the device tree in order
  to guarantee that all child devices are probed after the AEMIF timing
  parameters are configured.

  Some devices (e.g. da850) use struct of_dev_auxdata for clock lookup
  but nodes created from within the aemif driver can't access the lookup
  table.

  Create a platform data structure that holds a pointer to
  of_dev_auxdata so that we can use it with of_platform_populate().

  This platform driver has a OF device ID table but the OF module
  alias information is not created so module autoloading won't work.

  A platform_driver does not need to set an owner, it will be populated by the
  driver core.

• 5a7c81547   memory: ti-aemif: introduce AEMIF driver ... Browse Code »

  Add new AEMIF driver for EMIF16 Texas Instruments controller.
  The EMIF16 module is intended to provide a glue-less interface to
  a variety of asynchronous memory devices like ASRA M, NOR and NAND
  memory. A total of 256M bytes of any of these memories can be
  accessed at any given time via 4 chip selects with 64M byte access
  per chip select.

  Synchronous memories such as DDR1 SD RAM, SDR SDRAM and Mobile SDR
  are not supported.

  This controller is used on SoCs like Davinci, Keysone2
