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: clock div6 helper code

2009-06-11T06:07:13+00:00

This patch adds div6 clock helper code. The div6 clocks
are simply 6-bit divide-by-n modules where n is 1 to 64.

Needed for vclk on sh7722, sh7723, sh7343 and sh7366.
sh7724 needs this even more for vclk, fclka, fclkb,
irdaclk and spuclk.

sh: shared div4 clock code

2009-06-01T09:07:37+00:00

Add shared code for 4-bit divisor clocks.

Processor specific code can use SH_CLK_DIV4()
to initialize div4 clocks, and then use
sh_clk_div4_register() for registration.

sh: shared mstp32 clock code

2009-06-01T09:05:37+00:00

Add shared 32-bit module stop bit clock support.

Processor specific code can use SH_CLK_MSTP32()
to initialize module stop bit clocks, and then
use sh_clk_mstp32() for registration.

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: Update SH7785 for refactored clock framework.

2009-05-13T08:55:00+00:00

This updates the SH7785 CPU code as well as the SH7785LCR board support
code for making use of the newly refactored clock framework. Support for
the legacy CPG clocks is dropped at this point, with the extal frequency
fed in from the board code.
