config HAVE_CLK_PREPARE
	bool

config HAVE_MACH_CLKDEV
	bool

config COMMON_CLK
	bool
	select HAVE_CLK_PREPARE
	select CLKDEV_LOOKUP
	---help---
	  The common clock framework is a single definition of struct
	  clk, useful across many platforms, as well as an
	  implementation of the clock API in include/linux/clk.h.
	  Architectures utilizing the common struct clk should select
	  this option.

menu "Common Clock Framework"
	depends on COMMON_CLK

config COMMON_CLK_DEBUG
	bool "DebugFS representation of clock tree"
	select DEBUG_FS
	---help---
	  Creates a directory hierchy in debugfs for visualizing the clk
	  tree structure.  Each directory contains read-only members
	  that export information specific to that clk node: clk_rate,
	  clk_flags, clk_prepare_count, clk_enable_count &
	  clk_notifier_count.

config COMMON_CLK_WM831X
	tristate "Clock driver for WM831x/2x PMICs"
	depends on MFD_WM831X
	---help---
          Supports the clocking subsystem of the WM831x/2x series of
	  PMICs from Wolfson Microlectronics.

config COMMON_CLK_VERSATILE
	bool "Clock driver for ARM Reference designs"
	depends on ARCH_INTEGRATOR || ARCH_REALVIEW || ARCH_VEXPRESS || ARM64
	---help---
          Supports clocking on ARM Reference designs:
	  - Integrator/AP and Integrator/CP
	  - RealView PB1176, EB, PB11MP and PBX
	  - Versatile Express

config COMMON_CLK_MAX77686
	tristate "Clock driver for Maxim 77686 MFD"
	depends on MFD_MAX77686
	---help---
	  This driver supports Maxim 77686 crystal oscillator clock. 

config COMMON_CLK_SI5351
	tristate "Clock driver for SiLabs 5351A/B/C"
	depends on I2C
	select REGMAP_I2C
	select RATIONAL
	---help---
	  This driver supports Silicon Labs 5351A/B/C programmable clock
	  generators.

config CLK_TWL6040
	tristate "External McPDM functional clock from twl6040"
	depends on TWL6040_CORE
	---help---
	  Enable the external functional clock support on OMAP4+ platforms for
	  McPDM. McPDM module is using the external bit clock on the McPDM bus
	  as functional clock.

config COMMON_CLK_AXI_CLKGEN
	tristate "AXI clkgen driver"
	depends on ARCH_ZYNQ || MICROBLAZE
	help
	---help---
	  Support for the Analog Devices axi-clkgen pcore clock generator for Xilinx
	  FPGAs. It is commonly used in Analog Devices' reference designs.

config CLK_PPC_CORENET
	bool "Clock driver for PowerPC corenet platforms"
	depends on PPC_E500MC && OF
	---help---
	  This adds the clock driver support for Freescale PowerPC corenet
	  platforms using common clock framework.
