• 4bb73adec   OMAP2+: PRM: add register access functions for VC/VP ... Browse Code »

  On OMAP3+, the voltage controller (VC) and voltage processor (VP) are
  inside the PRM. Add some PRM helper functions for register access to
  these module registers.

  Thanks to Nishanth Menon for finding/fixing a sparse problem.

• 58aaa599a   OMAP2+: add PRM VP functions for checking/clearing VP TX done status ... Browse Code »

  Add SoC specific PRM VP helper functions for checking and clearing
  the VP transaction done status.

  Longer term, these events should be handled by the forthcoming PRCM
  interrupt handler.

• cc1226e76   OMAP2+: hwmod: use status bit info for reset line ... Browse Code »

  On OMAP2 and OMAP3 the reset ctrl shift doesn't match the
  status bit, as it does on OMAP4, when handling the reset lines.

  This patch adds a new member in the reset info structure, so now it
  can be added as part of hwmod data, and checked accordingly for
  OMAP2 or 3; otherwise, there could be cases when the shift masks
  doesn't match both of the registers, and a successful reset might
  throw an error message or vice versa.

  omap2plus_defocnfig build breaks when customised with only ARCH_OMAP4
  selected. This is because common files make references to the functions
  which are defined only for omap2xxx and omap3xxx.

  This patch adds stubs for these functions so that build continues to work.

  Now that OMAP4-specific PRCM functions have been added, distinguish the
  existing OMAP2/3-specific PRCM functions by prefixing them with "omap2_".

  This patch should not result in any functional change.

• 59fb659b0   OMAP2/3: PRCM: split OMAP2/3-specific PRCM code into OMAP2/3-specific files ... Browse Code »

  In preparation for adding OMAP4-specific PRCM accessor/mutator
  functions, split the existing OMAP2/3 PRCM code into OMAP2/3-specific
  files. Most of what was in mach-omap2/{cm,prm}.{c,h} has now been
  moved into mach-omap2/{cm,prm}2xxx_3xxx.{c,h}, since it was
  OMAP2xxx/3xxx-specific.

  This process also requires the #includes in each of these files to be
  changed to reference the new file name. As part of doing so, add some
  comments into plat-omap/sram.c and plat-omap/mcbsp.c, which use
  "sideways includes", to indicate that these users of the PRM/CM includes
  should not be doing so.

  Thanks to Felipe Contreras for comments on this
  patch.
