Merge tag 'tegra-for-3.9-soc-ccf' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra into next/soc
From Stephen Warren: ARM: tegra: Common Clock Framework rework Tegra already supports the common clock framework, but had issues: 1) The clock driver was located in arch/arm/mach-tegra/ rather than drivers/clk/. 2) A single "Tegra clock" type was implemented, rather than separate clock types for PLL, mux, divider, ... type in HW. 3) Clock lookups by device drivers were still driven by device name and connection ID, rather than through device tree. This pull request solves all three issues. This required some DT changes to add clocks properties, and driver changes to request clocks more "correctly". Finally, this rework allows all AUXDATA to be removed from Tegra board files, and various duplicate clock lookup entries to be removed from the driver. This pull request is based on the previous pull request, with tag tegra-for-3.9-cleanup. * tag 'tegra-for-3.9-soc-ccf' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra: (31 commits) clk: tegra30: remove unused TEGRA_CLK_DUPLICATE()s clk: tegra20: remove unused TEGRA_CLK_DUPLICATE()s ARM: tegra30: remove auxdata ARM: tegra20: remove auxdata ASoC: tegra: remove auxdata staging: nvec: remove use of clk_get_sys ARM: tegra: paz00: add clock information to DT ARM: tegra: add clock properties to Tegra30 DT ARM: tegra: add clock properties to Tegra20 DT spi: tegra: do not use clock name to get clock ARM: tegra: remove legacy clock code ARM: tegra: migrate to new clock code clk: tegra: add clock support for Tegra30 clk: tegra: add clock support for Tegra20 clk: tegra: add Tegra specific clocks ARM: tegra: define Tegra30 CAR binding ARM: tegra: define Tegra20 CAR binding ARM: tegra: move tegra_cpu_car.h to linux/clk/tegra.h ARM: tegra: add function to read chipid ARM: tegra: fix compile error when disable CPU_IDLE ...
