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

2014-02-04T01:22:39Z

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. Signed-off-by: Guennadi Liakhovetski Signed-off-by: Simon Horman

sh: clkfwk: bugfix: sh_clk_div_enable() care sh_clk_div_set_rate() if div6

2013-01-11T11:57:58Z

764f4e4e33d18cde4dcaf8a0d860b749c6d6d08b (sh: clkfwk: Use shared sh_clk_div_enable/disable()) shared enable/disable funcions for div4/div6. But new sh_clk_div_enable() didn't care sh_clk_div_set_rate() which is required on div6 clock. This patch fixes it. Signed-off-by: Kuninori Morimoto Signed-off-by: Paul Mundt

sh: clkfwk: fixup unsed variable warning

2012-11-13T02:45:40Z

This patch solves above warning ${LINUX}/drivers/sh/clk/cpg.c:404:6: warning: \ unused variable 'val' [-Wunused-variable] Signed-off-by: Kuninori Morimoto Signed-off-by: Simon Horman

sh: clkfwk: add sh_clk_fsidiv_register()

2012-11-08T06:21:30Z

This patch adds sh_clk_fsidiv_register() to share FSI-DIV clock code Signed-off-by: Kuninori Morimoto Acked-by: Paul Mundt Signed-off-by: Simon Horman

sh: clkfwk: Consolidate div clk registration helper.

2012-05-25T07:55:05Z

This consolidates the div6/4 versions of the clk registration wrapper. The existing wrappers with their own sh_clk_ops are maintained for API compatability, though in the future it should be possible to be rid of them entirely. Signed-off-by: Paul Mundt

sh: clkfwk: Consolidate div6/div4 clk_ops definitions.

2012-05-25T07:43:42Z

Everything with the exception of the _reparent ops are now shared, so switch everything over to common types. Signed-off-by: Paul Mundt

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

2012-05-25T07:34:48Z

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. Signed-off-by: Paul Mundt

sh: clkfwk: Use shared sh_clk_div_set_rate()

2012-05-25T06:52:10Z

Follows the sh_clk_div_recalc() change. Signed-off-by: Paul Mundt

sh: clkfwk: Use shared sh_clk_div_recalc().

2012-05-25T06:26:01Z

This generalizes the div4 recalc routine for use by div6 and others, then makes it the default. Signed-off-by: Paul Mundt

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

2012-05-25T06:21:43Z

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. Signed-off-by: Paul Mundt
