      imx: power optimization for i.mx8qm · 3a2b5199
      Anson Huang authored
      
      
      Current implementation of i.MX8QM power management related
      features does NOT optimize power number, all system resources
      like CCI, DDR, and A cluster etc. are kept in STBY mode (powered
      ON) when system suspend or CPU hotplug.
      
      To lower the power number, OFF mode should be adopted for those
      system resources whenever they can be OFF, A cluster will be OFF
      if the CPUs in the cluster are all off line, DDR/MU/DB can be OFF
      if system suspend, IRQ steer can be OFF if the wakeup source is
      belonged to system controller partition, so wakeup source runtime
      check is used to determine if IRQ steer can be OFF before system
      suspend.
      
      If resources are powered off for suspend, they should be restored
      properly after system resume.

      Sanitise includes across codebase · 09d40e0e
      Antonio Nino Diaz authored
      Enforce full include path for includes. Deprecate old paths.
      
      The following folders inside include/lib have been left unchanged:
      
      - include/lib/cpus/${ARCH}
      - include/lib/el3_runtime/${ARCH}
      
      The reason for this change is that having a global namespace for
      includes isn't a good idea. It defeats one of the advantages of having
      folders and it introduces problems that are sometimes subtle (because
      you may not know the header you are actually including if there are two
      of them).
      
      For example, this patch had to be created because two headers were
      called the same way: e0ea0928 ("Fix gpio includes of mt8173 platform
      to avoid collision."). More recently, this patch has had similar
      problems: 46f9b2c3 ("drivers: add tzc380 support").
      
      This problem was introduced in commit 4ecca339
      
       ("Move include and
      source files to logical locations"). At that time, there weren't too
      many headers so it wasn't a real issue. However, time has shown that
      this creates problems.
      
      Platforms that want to preserve the way they include headers may add the
      removed paths to PLAT_INCLUDES, but this is discouraged.
