* sh: convert cpg code to sh_clk_opsMagnus Damm2012-03-121-8/+8
| | | | | | | Convert the CPG code to use sh_clk_ops. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
* sh: clkfwk: bugfix: use clk_reparent() for div6 clocksKuninori Morimoto2012-01-241-1/+1
| | | | | | | | Various problems will happen if clk parent was set up directly. it should use clk_reparent() Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: clkfwk: sh_clk_init_parent() should be called after clk_register()Kuninori Morimoto2012-01-101-2/+2
| | | | | | | | sh_clk_init_parent() are using clk->mapped_reg which is mapped in clk_register() Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* sh: clkfwk: setup clock parent from current register valueKuninori Morimoto2011-11-241-0/+35
| | | | | | | | | | | Some clocks can select its parent clock by CPG register. But it might have been modified by boot-loader or something. This patch removed fixed initial parent clock, and setup it from their current register settings. It works on div6 reparent clocks for now.

* sh: clkfwk: fixup clk_rate_table_build parameter in div6 clockKuninori Morimoto2011-04-181-1/+1
| | | | | | | | | | div6 clock should not use arch_flags for clk_rate_table_build, because SH_CLK_DIV6_EXT doesn't care .arch_flags. clk->freq_table[] will be all CPUFREQ_ENTRY_INVALID without this patch.

* sh: clkfwk: Build fix for non-legacy CPG changes.Paul Mundt2010-11-191-1/+1
| | | | | | | | | The disabling of the init op for non-legacy clocks neglected to do the same in the core clock framework, resulting in a build failure. Fix it up. Reported-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: clkfwk: Kill off now unused algo_id in set_rate op.Paul Mundt2010-11-151-3/+2
| | | | | | | | Now that clk_set_rate_ex() is gone, there is also no way to get at rate setting algo id, which is now also completely unused. Kill it off before new clock ops start using it. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: clkfwk: Shuffle around to match the intc split up.Paul Mundt2010-10-181-0/+359
This shuffles the clock framework code around to a drivers/sh/clk subdir, to follow the intc split up. This will make it easier to subsequently break things out as well as plug in different helpers for non-CPG users. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
