      OMAP3: PM: fix save secure RAM to restore MPU power state · 617fcc98
      Kevin Hilman authored
      Currently, on HS/EMU devices, MPU power state forced to on during PM
      init by the save secure RAM code.  Rather than forcing the state of
      MPU powerdomain to on, simply read the current value and restore it
      after the ROM code has run.
      This only affects the !CPUidle case since when CPUidle is enabled, the
      MPU power state is dynamically changed by CPUidle.  In the !CPUidle
      case, MPU power state is initialized once at init and never touched.

      console: rename acquire/release_console_sem() to console_lock/unlock() · ac751efa
      Torben Hohn authored
      The -rt patches change the console_semaphore to console_mutex.  As a
      result, a quite large chunk of the patches changes all
      acquire/release_console_sem() to acquire/release_console_mutex()
      This commit makes things use more neutral function names which dont make
      implications about the underlying lock.
      The only real change is the return value of console_trylock which is
      inverted from try_acquire_console_sem()
      This patch also paves the way to switching console_sem from a semaphore to
      a mutex.

      OMAP: PRCM: remove duplicated headers · bc9fcaf3
      Felipe Balbi authored
      A few headers are included twice, remove them.

      OMAP4: clockdomain: bypass unimplemented wake-up dependency functions on OMAP4 · 56bc78d4
      Paul Walmsley authored
      Commit 56a6a19d ("omap2plus: prm:
      Trvial build break fix for undefined reference to
      'omap2_prm_read_mod_reg'") generates a lot of warnings on boot since
      clockdomain functions that manipulate wake-up dependencies are not
      implemented yet on OMAP4 for 2.6.38.  This patch bypasses the OMAP2/3
      functions on OMAP4, which in turn avoids the warnings when the
      functions would attempt to call the underlying OMAP2/3 PRCM functions.
      A one-line warning is still logged from the clockdomain code that the
      OMAP4 wake-up dependency code is not yet implemented.
      A clockdomain wake-up and sleep dependency implementation for OMAP4
      from Rajendra should be possible to merge during the 2.6.39 merge
