2016-11-02soc: renesas: Add R-Car RST driverGeert Uytterhoeven
Add a driver for the Renesas R-Car Gen1 RESET/WDT and R-Car Gen2/Gen3 and RZ/G RST module. For now this driver just provides an API to obtain the state of the mode pins, as latched at reset time. As this is typically called from the probe function of a clock driver, which can run much earlier than any initcall, calling rcar_rst_read_mode_pins() just forces an early initialization of the driver. Despite the current simple and almost identical handling for all supported SoCs, the driver matches against SoC-specific compatible values, as the features provided by the hardware module differ a lot across the various SoC families and members.

Add DT bindings for the Renesas R-Car Reset Controller (R-Car Gen1 RESET/WDT and R-Car Gen2/Gen3 and RZ/G RST). As the features provided by the hardware module differ a lot across the various SoC families and members, only SoC-specific compatible values are defined. For now we use the RST only for providing access to the state of the mode pins, which is needed by the clock driver.

2016-11-01clk: qcom: Add support for alpha pll hwfsm opsRajendra Nayak
Some PLLs can support an HW FSM mode (different from the Votable FSMs, though its the same bit used to enable Votable FSMs as well as HW FSMs) which enables the HW to do the bypass/reset/enable-output-ctrl sequence on its own. So all thats needed from SW is to set the FSM_ENA bit. PLL_ACTIVE_FLAG is whats used to check if the PLL is active/enabled. Some of the PLLs which support HW FSM can also need an OFFLINE request that needs to be toggled across the enable/disable. We use a flag to identify such cases and handle them.
