ARM: shmobile: wait for MSTP clock status to toggle, when enabling it

2014-02-04T01:22:39+00:00

On r-/sh-mobile SoCs MSTP clocks are used by the runtime PM to dynamically
enable and disable peripheral clocks. To make sure the clock has really
started we have to read back its status register until it confirms success.

sh: clkfwk: add sh_clk_fsidiv_register()

2012-11-08T06:21:30+00:00

This patch adds sh_clk_fsidiv_register() to share FSI-DIV clock code

sh: clkfwk: Use shared sh_clk_div_enable/disable().

2012-05-25T07:34:48+00:00

This introduces a new flag for clocks that need to have their divisor
ratio set back to their initial mask at disable time to prevent
interactivity problems with the clock stop bit (presently div6 only).
With this in place it's possible to handle the corner case on top of the
div4 op without any particular need for leaving things split out.

sh: clkfwk: Use shared sh_clk_div_recalc().

2012-05-25T06:26:01+00:00

This generalizes the div4 recalc routine for use by div6 and others, then
makes it the default.

sh: clkfwk: Introduce a div_mask for variable div types.

2012-05-25T06:21:43+00:00

This plugs in a div_mask for the clock and sets it up for the existing
div6/4 cases. This will make it possible to support other div types, as
well as share more div6/4 infrastructure.

sh: clkfwk: Move to common clk_div_table accessors for div4/div6.

2012-05-25T05:59:26+00:00

This plugs in a generic clk_div_table, based on the div4 version. div6 is
then adopted to use it for encapsulating its div table, which permits us
to start div6/4 unification, as well as preparation for other div types.

sh: clkfwk: Support variable size accesses for MSTP clocks.

2012-04-11T03:05:50+00:00

The bulk of the MSTP users require 32-bit access, but this isn't the case
for some of the SH-2A parts, so add in some basic infrastructure to let
the CPU define its required access size in preparation.

sh: remove clk_ops

2012-03-12T21:19:13+00:00

Now when all clk_ops have been renamed it is
safe to rename clk_ops to sh_clk_ops.

sh: extend clock struct with mapped_reg member

2011-12-09T09:01:05+00:00

Add a "mapped_reg" member to struct clk and use that
to keep the ioremapped register based on enable_reg.
