      gpiolib: replace strict_strtol() with kstrtol() · a3d88c92
      Jingoo Han authored
      The usage of strict_strtol() is not preferred, because
      strict_strtol() is obsolete. Thus, kstrtol() should be
      used.

      gpio-tz1090: convert to use generic irqchip · 04777396
      James Hogan authored
      Convert gpio-tz1090 driver to use generic irqchips. This allows the
      irq_ack, irq_mask, and irq_unmask callbacks and associated helper
      functions to be removed. Also switch to using irq_setup_alt_chip() in
      the irq_set_type callback instead of using __irq_set_handler_locked().

      gpio-tz1090-pdc: add TZ1090 PDC gpio driver · 79bb6460
      James Hogan authored
      Add a GPIO driver for the low-power Powerdown Controller GPIOs in the
      TZ1090 SoC.
      
      The driver is instantiated by device tree and supports interrupts for
      the SysWake GPIOs only.
      
      Changes in v4:
       - fix typos in DT bindings compatible properties
       - reference Documentation/devicetree/bindings/gpio/gpio.txt in
         gpio-ranges description in DT bindings
       - fix gpio-ranges examples in DT bindings (it must now have 3 cells)
      
      Changes in v3:
       - separated from irq-imgpdc and removed arch/metag changes to allow
         these patches to go upstream separately via the pinctrl[/gpio] trees
         (particularly the pinctrl drivers depend on the new pinconf DT
         bindings).
       - some s/unsigned/unsigned int/.
       - gpio-tz1090*: refer to <dt-bindings/gpio/gpio.h> and
         <dt-bindings/interrupt-controller/irq.h> flags in bindings.
       - gpio-tz1090*: move initcall from postcore to subsys.
      
      Changes in v2:
       - gpio-tz1090-pdc: remove references to Linux flags in dt bindings
       - gpio-tz1090-pdc: make use of BIT() from linux/bitops.h
       - gpio-tz1090-pdc: make register accessors inline to match pinctrl
       - gpio-tz1090-pdc: update gpio-ranges to use 3 cells after recent ABI

      James Hogan authored
      Add a GPIO driver for the main GPIOs found in the TZ1090 (Comet) SoC.
      This doesn't include low-power GPIOs as they're controlled separately
      via the Powerdown Controller (PDC) registers.
      
      The driver is instantiated by device tree and supports interrupts for
      all GPIOs.

      Pull slab update from Pekka Enberg:
       "Highlights:
      
        - Fix for boot-time problems on some architectures due to

      I ended up editing the branch, and this avoids two commits at the end
      that were immediately reverted, and I instead just applied the oneliner
      fix in between myself.

      Now, this uses SLUB pretty much unmodified, but as it is the -rt kernel
      with CONFIG_PREEMPT_RT set, spinlocks are mutexes, although they do
      disable migration. But the SLUB code is relatively lockless, and the
      spin_locks there are raw_spin_locks (not converted to mutexes), thus I
      believe this bug can happen in mainline without -rt features. The -rt
      patch is just good at triggering mainline bugs ;-)
      
      Anyway, looking at where this crashed, it seems that the page variable
      can be NULL when passed to the node_match() function (which does not
      check if it is NULL). When this happens we get the above panic.
      
      As page is only used in slab_alloc() to check if the node matches, if
      it's NULL I'm assuming that we can say it doesn't and call the
      __slab_alloc() code. Is this a correct assumption?
