• b6d4f3221   lib/stmp_device.c: replace module.h include ... Browse Code »

  stmp_device.c only needs EXPORT_SYMBOL, so just include compiler.h and
  export.h instead of the whole module.h machinery.

• 4ccf4beab   lib: add support for stmp-style devices ... Browse Code »

  MX23/28 use IP cores which follow a register layout I have first seen on
  STMP3xxx SoCs. In this layout, every register actually has four u32:

  1.) to store a value directly
  2.) a SET register where every 1-bit sets the corresponding bit,
  others are unaffected
  3.) same with a CLR register
  4.) same with a TOG (toggle) register

  Also, the 2 MSBs in register 0 are always the same and can be used to reset
  the IP core.

  All this is strictly speaking not mach-specific (but IP core specific) and,
  thus, doesn't need to be in mach-mxs/include. At least mx6 also uses IP cores
  following this stmp-style. So:

  Introduce a stmp-style device, put the code and defines for that in a public
  place (lib/), and let drivers for stmp-style devices select that code.
  To avoid regressions and ease reviewing, the actual code is simply copied from
  mach-mxs. It definately wants updates, but those need a seperate patch series.

  Voila, mach dependency gone, reusable code introduced. Note that I didn't
  remove the duplicated code from mach-mxs yet, first the drivers have to be
  converted.
