      gpio: Don't override the error code in probe error handling · cfb10898
      Axel Lin authored
      Otherwise, we return 0 in probe error paths when gpiochip_remove() returns 0.
      Also show error message if gpiochip_remove() fails.

      gpio: mxs: Use set and clear capabilities of the gpio controller · 90dae4eb
      Maxime Ripard authored
      The current driver doesn't use the set and clear registers found on the
      mxs gpio controller.
      
      This leads the generic gpio controller to be using some internal value
      to avoid looking up the value stored in the registers, making it behave
      pretty much like a cache.
      
      This raises some coherency problem when a gpio is not modified by the
      gpio controller, while it can easily be fixed by using the set and clear
      registers.

      gpio-langwell: fix irq conflicts when DT is not used · 2519f9ab
      David Cohen authored
      When DT is not used IOAPIC does not register irq domain. As result
      IOAPIC won't care about gpio-langwell's virq and may cause conflict if
      an irq number is equal to gpio-langwell's virq mapped beforehand.
      
      This patch tells gpio_langwell to not ignore irq_base if != 0 and
      preferably use it to avoid the conflict.
      
      If DT is used, irq_base can safely be 0.

      gpio: mcp23s08: Fix build error when CONFIG_SPI_MASTER=y && CONFIG_I2C=m · 0f119a84
      Axel Lin authored
      This patch fixes below build error when CONFIG_SPI_MASTER=y && CONFIG_I2C=m &&
      CONFIG_GPIO_MCP23S08=y.

      make: *** [vmlinux] Error 1
      
      When CONFIG_I2C=m, meaning we can't build the drivers in with I2C support.
      Thus don't allow the drivers to be compiled as built-in when CONFIG_I2C=m.
      
      The real fix though is to break the driver apart into a SPI part, an I2C part
      and a common part. But that's something for 3.11 while this is something for
      3.10/stable.

      gpio/omap: ensure gpio context is initialised · 352a2d5b
      Jon Hunter authored
      Commit a2797bea (gpio/omap: force restore if context loss is not
      detectable) broke gpio support for OMAP when booting with device-tree
      because a restore of the gpio context being performed without ever
      initialising the gpio context. In other words, the context restored was
      bad.
      
      This problem could also occur in the non device-tree case, however, it
      is much less likely because when booting without device-tree we can
      detect context loss via a platform specific API and so context restore
      is performed less often.
      
      Nevertheless we should ensure that the gpio context is initialised
      on the first pm-runtime resume for gpio banks that could lose their
      state regardless of whether we are booting with device-tree or not.
      
      The context loss count was being initialised on the first pm-runtime
      suspend following a resume, by populating the get_count_loss_count()
      function pointer after the first pm-runtime resume. To make the code
      more readable and logical, initialise the context loss count on the
      first pm-runtime resume if the context is not yet valid.

       "The majority of these changes are from Masami Hiramatsu bringing
        kprobes up to par with the latest changes to ftrace (multi buffering

        He also discovered and fixed some bugs in doing so.  When pulling in
        his patches, I also found a few minor bugs as well and fixed them.
      
        This also includes a compile fix for some archs that select the ring
        buffer but not tracing.
      
        I based this off of the last patch you took from me that fixed the
        merge conflict error, as that was the commit that had all the changes
        I needed for this set of changes."
