      ARM: dove: create a proper PMU driver for power domains, PMU IRQs and resets · 44e259ac
      Russell King authored
      The PMU device contains an interrupt controller, power control and
      resets.  The interrupt controller is a little sub-standard in that
      there is no race free way to clear down pending interrupts, so we try
      to avoid problems by reducing the window as much as possible, and
      clearing as infrequently as possible.
      
      The interrupt support is implemented using an IRQ domain, and the
      parent interrupt referenced in the standard DT way.
      
      The power domains and reset support is closely related - there is a
      defined sequence for powering down a domain which is tightly coupled
      with asserting the reset.  Hence, it makes sense to group these two
      together, and in order to avoid any locking contention disrupting this
      sequence, we avoid the use of syscon or regmap.
      
      This patch adds the core PMU driver: power domains must be defined in
      the DT file in order to make use of them.  The reset controller can
      be referenced in the standard way for reset controllers.

      ARM: mvebu: Warn about the wake-up sources not taken into account in suspend · 482d638f
      Gregory CLEMENT authored
      On the Armada 370/XP/38x/39x SoCs when the suspend to ram feature is
      supported, the SoCs are shutdown and will be woken up by an external
      micro-controller, so there is no possibility to setup wake-up sources
      from Linux. However, in standby mode, the SoCs stay powered and it is
      possible to wake-up from any interrupt sources. Since when the users
      configures the enabled wake-up sources there is no way to know if the
      user will be doing suspend to RAM or standby, we just allow all
      wake-up sources to be enabled, and only warn when entering suspend to
      RAM
      
      The purpose of this patch is to inform the user that in suspend to ram
      mode, the wake-up sources won't be taken into consideration.

      bluetooth: fix list handling · 9b284cbd
      Linus Torvalds authored
      Commit 835a6a2f ("Bluetooth: Stop sabotaging list poisoning")
      thought that the code was sabotaging the list poisoning when NULL'ing
      out the list pointers and removed it.
      
      But what was going on was that the bluetooth code was using NULL
      pointers for the list as a way to mark it empty, and that commit just
      broke it (and replaced the test with NULL with a "list_empty()" test on
      a uninitialized list instead, breaking things even further).
      
      So fix it all up to use the regular and real list_empty() handling
      (which does not use NULL, but a pointer to itself), also making sure to
      initialize the list properly (the previous NULL case was initialized
      implicitly by the session being allocated with kzalloc())
      
      This is a combination of patches by Marcel Holtmann and Tedd Ho-Jeong
      An.
      
      [ I would normally expect to get this through the bt tree, but I'm going
        to release -rc1, so I'm just committing this directly   - Linus ]
