clk: composite: rename 'div' references to 'rate'

2013-04-12T18:22:35+00:00

Rename all div_hw and div_ops related variables and functions to use
rate_hw, rate_ops, etc.  This is to make the rate-change portion of the
composite clk implementation more generic.  A patch following this one
will allow for fixed-rate clocks to reuse this infrastructure.

factor clock support.

clk: divider: Introduce CLK_DIVIDER_ALLOW_ZERO flag

2013-04-03T19:56:30+00:00

Dividers which have CLK_DIVIDER_ONE_BASED set have a redundant state,
being a divider value of zero. Some hardware implementations allow a
zero divider which simply doesn't alter the frequency. I.e. it acts like
a divide by one or bypassing the divider.
This flag is used to handle such HW in the clk-divider model.

clk: fix clk_mux::flags kerneldoc

2013-04-02T23:50:26+00:00

The kerneldoc comment for struct clk_mux documented the non-existent
num_clks instead of flags. Correct this.

clk: Add composite clock type

2013-03-26T19:51:48+00:00

Not all clocks are required to be decomposed into basic clock
types but at the same time want to use the functionality
provided by these basic clock types instead of duplicating.

For example, Tegra SoC has ~100 clocks which can be decomposed
into Mux -> Div -> Gate clock types making the clock count to
~300. Also, parent change operation can not be performed on gate
clock which forces to use mux clock in driver if want to change
the parent.

Instead aggregate the basic clock types functionality into one
clock and just use this clock for all operations. This clock
type re-uses the functionality of basic clock types and not
limited to basic clock types but any hardware-specific
implementation.

clk: add table lookup to mux

2013-03-22T22:18:18+00:00

Add a table lookup feature to the mux clock. Also allow arbitrary masks
instead of the width. This will be used by some clocks on Tegra114. Also
adapt the tegra periph clk because it uses struct clk_mux directly.

clk: Introduce optional unprepare_unused callback

2013-03-19T19:58:43+00:00

An unprepare_unused callback is introduced due to the same reasons to
why the disable_unused callback was added.

During the clk_disable_unused sequence, those clk_hw that needs specific
treatment with regards to being unprepared, shall implement the
unprepare_unused callback.

clk: Introduce optional is_prepared callback

2013-03-19T19:58:42+00:00

To reflect whether a clk_hw is prepared the clk_hw may implement
the optional is_prepared callback. If not implemented we fall back
to use the software prepare counter.

clk: add common of_clk_init() function

2013-01-24T19:09:28+00:00

Modify of_clk_init function so that it will determine which
driver to initialize based on device tree instead of each driver
registering to it.

Based on a similar patch for drivers/irqchip by Thomas Petazzoni and
drivers/clocksource by Stephen Warren.

Pull clock framework changes from Mike Turquette:
 "The common clock framework changes for 3.8 are comprised of lots of
  fixes for existing platforms as well as new ports for some ARM
  platforms.  In addition there are new clk drivers for audio devices
  and MFDs."

clashing with return type fixes)
