sh: add enable()/disable()/set_rate() to div6 code

2009-06-11T06:12:58+00:00

This patch updates the div6 clock helper code to add support
for enable(), disable() and set_rate() callbacks.

Needed by the camera clock enabling board code on Migo-R.

sh: remove clk_ops->build_rate_table()

2009-05-26T08:08:45+00:00

This patch removes the ->build_rate_table() callback,
->recalc() may instead be used for this purpose.

sh: add shared clock framework frequency table code

2009-05-26T08:08:39+00:00

Add SuperH-specific clock framework helper functions:
- clk_rate_table_build() - build cpufreq table from divisors/multipliers
- clk_rate_table_round() - use cpufreq table to find matching frequency

sh: clkfwk: Add MSTP bits to SH7785 clock framework.

2009-05-14T08:38:46+00:00

This plugs in all of the MSTP functions in to the clock framework,
and hands them off to the platform devices that want them.

sh: clkfwk: Map tree hierarchy in debugfs.

2009-05-13T12:51:28+00:00

This adopts the OMAP clock framework debugfs bits and replaces the aging
procfs bits. The procfs clocks entry was primarily a debugging aid, and
used to be tied in to cpuinfo before the clock list grew too unweildly.

sh: clkfwk: rate table construction and rounding for SH7785.

2009-05-13T11:28:15+00:00

This adds support for constructing a rate table by looking at potential
divisors for a specified clock. Each FQRMR clock is given its own table.
Presently each table is rebuilt when the parent propagates down a new
rate, so some more logic needs to be added to do this more intelligently.

Additionally, a fairly generic round_rate() implementation is then
layered on top of it, which subsequently provides us with cpufreq support.

sh: clkfwk: Rework legacy CPG clock handling.

2009-05-13T08:38:11+00:00

This moves out the old legacy CPG clocks to their own file, and converts
over the existing users. With these clocks going away and each CPU
dealing with them on their own, CPUs can gradually move over to the new
interface.

sh: clkfwk: Provide a generic clk_set_rate_ex() path for root clocks.

2009-05-13T08:05:51+00:00

In the case of root clocks (such as clkin oscillators, extal, etc.), the
rate information is entirely platform dependent and needs to be lazily
set and propagated from the platform code. This provides a method for
establishing the rate update on these types of clocks that define no
set_rate() op of their own.

sh: clkfwk: Handle NULL clkops for root clocks.

2009-05-13T08:03:09+00:00

root clocks may simply be placeholders for rate and ancestry information,
and have no real associated operations of their own. Account for this,
so we are still able to use these sorts of clocks for rate propagation.
