clock: max77686: Add driver for Maxim 77686 32Khz crystal oscillator.

2012-09-06T23:55:38+00:00

This patch supports max77686 mfd's clock driver using common clock frame work. max77686 has 3 clock ouputs which all are generated from crystal oscillator and SOC can enable/disable them via I2C bus. All clocks are fixed-rate clock sources so that it doesn't supply interface for changing clock rate. Driver uses regmap API to communicate with internal register.

clk: versatile: make config option boolean

2012-09-04T22:28:42+00:00

There is no choice to have the RealView clocks as module for sure, so turn this config option into a boolean. Reported-by: Pawel Moll Signed-off-by: Linus Walleij Signed-off-by: Mike Turquette

clk: convert ARM RealView to common clk

2012-08-25T00:42:10+00:00

This converts the ARM RealView machine over to using the common clock. The approach is similar to the one used for the Integrator, and we're reusing the ICST wrapper code. We have to put the clock intialization in the timer init function for the clocks to be available when initializing the timer, keeping them in early_init() is too early for the common clk. Since we now have to go down and compile drivers/clk/versatile a CONFIG_COMMON_CLK_VERSATILE symbol has been added so the proper code gets compiled into the kernel for either machine. A leftover CLK_VERSATILE in the Integrator Kconfig was fixed up to use the new symbol as well. Tested on ARM RealView PB1176.

clk: remove redundant depends on from drivers/Kconfig

2012-07-31T00:25:12+00:00

menu "Common Clock Framework" has "depends on COMMON_CLK" and so configs defined within menu don't require these "depends on COMMON_CLK again".

clk: wm831x: Add initial WM831x clock driver

2012-07-11T22:36:44+00:00

The WM831x and WM832x series of PMICs contain a flexible clocking subsystem intended to provide always on and system core clocks. It features: - A 32.768kHz crystal oscillator which can optionally be used to pass through an externally generated clock. - A FLL which can be clocked from either the 32.768kHz oscillator or the CLKIN pin. - A CLKOUT pin which can bring out either the oscillator or the FLL output. - The 32.768kHz clock can also optionally be brought out on the GPIO pins of the device. This driver fully supports the 32.768kHz oscillator and CLKOUT. The FLL is supported only in AUTO mode, the full flexibility of the FLL cannot currently be used. Due to a lack of access to systems where the core SoC has been converted to use the generic clock API this driver has been compile tested only.

clk: remove COMMON_CLK_DISABLE_UNUSED

Exposing this option generates confusion and incorrect behavior for single-image builds across platforms. Enable this behavior permanently. Signed-off-by: Mike Turquette Acked-by: Saravana Kannan

clk: select CLKDEV_LOOKUP for COMMON_CLK

2012-04-24T23:37:41+00:00

Using the common clock infrastructure without the common clkdev code makes little sense, so select CLKDEV_LOOKUP for COMMON_CLK. Signed-off-by: Rob Herring

clk: make CONFIG_COMMON_CLK invisible

2012-03-19T09:37:11+00:00

All platforms that use the common clk infrastructure should select COMMON_CLK from platform code, and on all other platforms, it must not be enabled, so there is no point making the option visible to users, and when it is visible, we break randconfig builds. Signed-off-by: Arnd Bergmann

clk: introduce the common clock framework

2012-03-16T20:35:01+00:00

The common clock framework defines a common struct clk useful across most platforms as well as an implementation of the clk api that drivers can use safely for managing clocks. The net result is consolidation of many different struct clk definitions and platform-specific clock framework implementations. This patch introduces the common struct clk, struct clk_ops and an implementation of the well-known clock api in include/clk/clk.h. Platforms may define their own hardware-specific clock structure and their own clock operation callbacks, so long as it wraps an instance of struct clk_hw. See Documentation/clk.txt for more details. This patch is based on the work of Jeremy Kerr, which in turn was based on the work of Ben Herrenschmidt.

clk: add config option HAVE_CLK_PREPARE into Kconfig

2011-12-28T13:35:06+00:00

The commit 40d3e0f (clk: provide prepare/unprepare functions) provides the config option HAVE_CLK_PREPARE for platforms that have prepare/unprepare implementation to select. This patch adds the option into drivers/clk/Kconfig, so that it can be actually selected. Signed-off-by: Shawn Guo Cc: Russell King
