Merge tag 'tegra-for-3.7-drivers-i2c' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra into next/drivers
From Stephen Warren: ARM: tegra: i2c driver enhancements mostly related to clocking This branch contains a number of fixes and cleanups to the Tegra I2C driver related to clocks. These are based on the common clock conversion in order to avoid duplicating the clock driver changes before and after the conversion. Finally, a bug-fix related to I2C_M_NOSTART is included. This branch is based on previous pull request tegra-for-3.7-common-clk. * tag 'tegra-for-3.7-drivers-i2c' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra: i2c: tegra: dynamically control fast clk i2c: tegra: I2_M_NOSTART functionality not supported in Tegra20 ARM: tegra: clock: remove unused clock entry for i2c ARM: tegra: clock: add connection name in i2c clock entry i2c: tegra: pass proper name for getting clock ARM: tegra: clock: add i2c fast clock entry in clock table ARM: Tegra: Add smp_twd clock for Tegra20 ARM: tegra: cpu-tegra: explicitly manage re-parenting ARM: tegra: fix overflow in tegra20_pll_clk_round_rate() ARM: tegra: Fix data type for io address ARM: tegra: remove tegra_timer from tegra_list_clks ARM: tegra30: clocks: fix the wrong tegra_audio_sync_clk_ops name ARM: tegra: clocks: separate tegra_clk_32k_ops from Tegra20 and Tegra30 ARM: tegra: Remove duplicate code ARM: tegra: Port tegra to generic clock framework ARM: tegra: Add clk_tegra structure and helper functions ARM: tegra: Rename tegra20 clock file ARM: tegra20: Separate out clk ops and clk data ARM: tegra30: Separate out clk ops and clk data ARM: tegra: fix U16 divider range check ... + sync to v3.6-rc4 Resolved remove/modify conflict in arch/arm/mach-sa1100/leds-hackkit.c caused by the sync with v3.6-rc4.
