      ARM: dts: Disable the RTC by default on exynos5 · 522ccdb6
      Doug Anderson authored
      
      
      This change makes the rtc on the exynos5250 and 5440 disabled by
      default to match exynos4.
      
      Ever since the common clock framework came in, exynos5250 boards
      have dumped lots of warnings in the boot log. It turns out that
      we don't see those on exynos4 since the rtc is disabled by default.
      While we need to get to the bottom of the problems with the RTC,
      it still makes sense to have the default state of the RTC on exynos
      boards match.
      
      For the record, warnings look like this:
        ------------[ cut here ]------------

      Olof Johansson authored
      This reverts commit bd51de53
      
      .
      
      Turns out that multiplatform breaks some uses cases, such as when you
      have an existing defconfig, since it adds the new EXYNOS_SINGLE config
      option as a dependecy. As a result, nearly all exynos config options
      will be disabled by default.
      
      Reverting instead of rebasing since this branch is pulled in as a
      dependency elsewhere.

      ARM: tegra: clock driver development
      
      This branch contains most fixes and enhancements to the Tegra common
      clock driver. The main new feature is a driver for Tegra114, which
      coupled with later device tree changes enables many devices on that
      chip, such as MMC, I2C, etc.
      
      This branch depends on a patch in:
      
      git://git.linaro.org/people/mturquette/linux.git clk-for-3.10
      
      Mike has stated that this branch is stable, and is aware of this
      dependency and merge.
      
      Mike's branch is based on v3.9-rc3, which includes a USB change which
      causes problems on Tegra. That problem was fixed in v3.9-rc4. Hence,
      this branch pulls in v3.9-rc4 to ensure bisectability as much as
      possible.
      
      This branch is based on v3.9-rc4, followed by a merge of previous Tegra
      "soc" pull request, followed by a merge of clk-for-3.10.

      This series consists mainly of clean-ups for clockevents and

      ARM: EXYNOS: Add arm-pmu DT binding for exynos421x · db35234e

      This patch adds a arm-pmu node to bind device tree for exynos4210.
      The exynos4210 and 4212 have two cpus which includes a pmu. In contrast, the
      exynos4412 has 4 cpus and pmus. We need to define two more pmus for this type
      board. However, supporting arm-pmu for the exynos4412 will handle it later
      because there is no dts support for 4412 based board.

      ARM: EXYNOS: Enable PMUs for exynos4 · b7bbdbee
      Chanho Park authored
      
      
      This patch defines irq numbers of ARM performance monitoring unit for exynos4.
      Firs of all, we need to fix IRQ_PMU correctly and to split pmu initialization
      of exynos from plat-samsung for easily defining it.
      
      The number of CPU cores and PMU irq numbers are vary according to soc types.
      So, we need to identify each soc type using soc_is_xxx function and to define
      the pmu irqs dynamically. For example, the exynos4412 has 4 cpu cores and pmus.

      irqchip: exynos-combiner: Add set_irq_affinity function for combiner_irq · df7ef462
      Chanho Park authored
      
      
      This patch adds set_irq_affinity function for combiner_irq. We need this
      function to enable a arm-pmu because the pmu of exynos has combined type
      irqs.
