      ARM: dts: am335x-sl50: use phy-phandle declarations · 25d2ee9f
      Enric Balletbo i Serra authored
      phy-phandle is now a preferred method to reference a PHY device. The new
      method also allows you to specify a reset gpio which is required for
      this board.

      ARM: dts: am335x-sl50: update backlight nodes · 7c128026
      Enric Balletbo i Serra authored
      This patch updates the backlight nodes to improve the support and describe
      better how hardware is done. The changes done were:
      
       * Use PWM_POLARITY_INVERTED instead of the hardcoded number.
       * Add pinctrl configuration.
       * Add the enable gpio definition.
       * Add the power supply definition.
       * Add more brightness levels.

      ARM: dts: omap4-droid4: Use software debounce for gpio-keys · e40c7f75
      Tony Lindgren authored
      The default value of 5ms will use GPIO hardware based debounce clocks
      that will keep L4PER from idling consuming about extra 30mW.
      
      Use a value of 10ms that is above the hardware debounce maximum of
      7.95ms forcing software based debouncing.
      
      This allows droid4 to enter PER retention during idle as long as UARTs
      are idled and USB modules unloaded or unbound.
      
      Note that there seems to be a pending issue with having droid 4 enter core
      retention during idle where GPIO bank 1 needs to be reset late after init
      for some reason to not block core retention. In addition to that, we are
      also missing GPIO related PM runtime calls for omap4 that will be posted
      separately.

      ARM: dts: Configure duovero for to allow core retention during idle · 731b4098
      Tony Lindgren authored
      By reconfiguring few GPIOs in the dts file we can make duovero parlor
      hit retention during idle:
      
      1. Let's a larger debounce value for gpio-keys
      
      This will then make gpio-keys use software debounce and the GPIO
      debounce clock is not enabled.
      
      2. Let's allow WLAN suspend for mwifiex
      
      This can be done just by adding keep-power-in-suspend.
      
      3. Let's reconfigure smsc911x driver to use GPIO edge interrupt
      
      This will allow using NFSroot while the system idles, and the kernel
      has quite a few dts files with "smsc,lan9115" compatible using edge
      interrupts.
      
      Then to have the system hit core retention during idle, the UARTs
      needs to be idled and USB modules need to be unloaded or unbound.

      ARM: dts: Improve omap l4per idling with wlcore edge sensitive interrupt · 572cf7d7
      Tony Lindgren authored
      The wl1835mod.pdf data sheet says this pretty clearly for WL_IRQ line:
      
      "WLAN SDIO out-of-band interrupt line. Set to rising edge (active high)
      by default."
      
      And it seems this interrupt can be optionally configured to use falling
      edge too since commit bd763482 ("wl18xx: wlan_irq: support platform
      dependent interrupt types").
      
      On omap4, if the wlcore interrupt is configured as level instead of edge,
      L4PER will stop doing hardware based idling after ifconfig wlan0 down is
      done and the WL_EN line is pulled down.
      
      The symptoms show up with L4PER status registers no longer showing the
      IDLEST bits as 2 but as 0 for all the active GPIO banks and for
      L4PER_CLKCTRL. Also the l4per_pwrdm RET count stops increasing in
      the /sys/kernel/debug/pm_debug/count.
      
      While there is also probably a GPIO related issue that needs to be
      still fixed, this change gets us to the point where we can have L4PER
      idling.
      
      I'm guessing wlcore was at some point configured to use level interrupts
      because of edge handling issues in gpio-omap. However, with the recent
      fixes to gpio-omap the edge interrupts seem to be working just fine.
      
      Let's change it for all omap boards with wlcore interrupt set as level.

      ARM: dts: omap5: Add missing cooling device properties for CPUs · 484d578b
      Viresh Kumar authored
      The cooling device properties, like "#cooling-cells" and
      "dynamic-power-coefficient", should either be present for all the CPUs
      of a cluster or none. If these are present only for a subset of CPUs of
      a cluster then things will start falling apart as soon as the CPUs are
      brought online in a different order. For example, this will happen
      because the operating system looks for such properties in the CPU node
      it is trying to bring up, so that it can register a cooling device.
      
      Add such missing properties.
      
      Fix other missing properties (clocks, supply, clock latency) as well to
      make it all work.

      There doesn't seem to be a need to have each regulator in the

      regulator has a min and max setting.
