      gpio: syscon: reuse for keystone 2 socs · 2134cb99
      Grygorii Strashko authored
      On Keystone SOCs, ARM host can send interrupts to DSP cores using the
      DSP GPIO controller IP. Each DSP GPIO controller provides 28 IRQ signals for
      each DSP core. This is one of the component used by the IPC mechanism used
      on Keystone SOCs.
      
      Keystone 2 DSP GPIO controller has specific features:
      - each GPIO can be configured only as output pin;
      - setting GPIO value to 1 causes IRQ generation on target DSP core;
      - reading pin value returns 0 - if IRQ was handled or 1 - IRQ is still
        pending.
      
      This patch updates gpio-syscon driver to be reused by Keystone 2 SoCs,
      because the Keystone 2 DSP GPIO controller is controlled through Syscon
      devices and, as requested by Linus Walleij, such kind of GPIO controllers
      should be integrated with drivers/gpio/gpio-syscon.c driver.

      gpio: syscon: retrive syscon node and regs offsets from dt · 5a3e3f88
      Grygorii Strashko authored
      This patch adds handling of new "gpio,syscon-dev" DT property,
      which allows to specify syscon node and data/direction registers
      offsets in DT.
      
      "gpio,syscon-dev" has following format:
      	gpio,syscon-dev = <&syscon_dev data_reg_offset [direction_reg_offset]>;
      
      where
       - syscon_dev - phandle on syscon node
       - data_reg_offset - offset of data register (in bytes)
       - direction_reg_offset - offset of dirrection register (optional, in bytes)
      
      for example:
      	gpio,syscon-dev = <&devctrl 0x254>;
      
      In such way, the support of multiple Syscon GPIO devices is added.

      gpio: syscon: add soc specific callback to assign output value · 2c341d62
      Grygorii Strashko authored
      Some SoCs (like Keystone) may require to perform special
      sequence of operations to assign output GPIO value, so default
      implementation of .set() callback from gpio-syscon driver
      can't be used.
      
      Hence, add optional, SoC specific callback to assign output
      gpio value.

      Pull fix for ftrace function tracer/profiler conflict from Steven Rostedt:
       "The rewrite of the ftrace code that makes it possible to allow for
        separate trampolines had a design flaw with the interaction between
        the function and function_graph tracers.
      
        The main flaw was the simplification of the use of multiple tracers
        having the same filter (like function and function_graph, that use the
        set_ftrace_filter file to filter their code).  The design assumed that
        the two tracers could never run simultaneously as only one tracer can
        be used at a time.  The problem with this assumption was that the
        function profiler could be implemented on top of the function graph
        tracer, and the function profiler could run at the same time as the
        function tracer.  This caused the assumption to be broken and when
        ftrace detected this failed assumpiton it would spit out a nasty
        warning and shut itself down.
      
        Instead of using a single ftrace_ops that switches between the
        function and function_graph callbacks, the two tracers can again use
        their own ftrace_ops.  But instead of having a complex hierarchy of
        ftrace_ops, the filter fields are placed in its own structure and the
        ftrace_ops can carefully use the same filter.  This change took a bit
        to be able to allow for this and currently only the global_ops can
        share the same filter, but this new design can easily be modified to
        allow for any ftrace_ops to share its filter with another ftrace_ops.
      
        The first four patches deal with the change of allowing the ftrace_ops
        to share the filter (and this needs to go to 3.16 as well).
      
        The fifth patch fixes a bug that was also caused by the new changes
        but only for archs other than x86, and only if those archs implement a
        direct call to the function_graph tracer which they do not do yet but
        will in the future.  It does not need to go to stable, but needs to be
        fixed before the other archs update their code to allow direct calls
        to the function_graph trampoline"
