* sh: Rename sci_ick and sci_fck clock to fckLaurent Pinchart2015-12-171-6/+6
| | | | | | | | | | | The SCI driver requires a functional clock named "fck" and falls back to "sci_ick" or "sci_fck" when the "fck" clock doesn't exist. To allow removal of the fallback code rename the sci_ick and sci_fck clocks to fck for all SH platforms.

* SH: use clkdev_add_table()Russell King2015-05-061-2/+2
| | | | | | | | | | | We have always had an efficient way of registering a table of clock lookups - it's called clkdev_add_table(). However, some people seem to really love writing inefficient and unnecessary code. Convert SH to use the correct interface.

* sh: Switch to new style TMU deviceLaurent Pinchart2014-05-111-12/+4
| | | | | | | | | The TMU (Timer Unit) driver implements a new style of platform data that handles the timer as a single device with multiple channel. Switch from the old-style platform data to the new-style platform data.

* sh: switch sh7786 to clkdevMagnus Damm2010-05-131-4/+4
| | | | | | | | | This patch converts the remaining sh7786 clocks to use clkdev for lookup. The now unused name and id from struct clk are also removed. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: get rid of div4 clock nameMagnus Damm2010-05-131-8/+8
| | | | | | | | | Remove the name parameter from SH_CLK_DIV4() and adjust the processor specific code. The lookup happens using clkdev so the name is unused. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* sh: sh7786 clkdev lookups.Paul Mundt2010-03-291-0/+68
| | | | | | | | | | This plugs in clkdev lookups for the SH7786 clocks and migrates off of clock string usage for the TMU clocks. Previously the TMU clocks were aliased to the peripheral clock, so this gets the driver actually toggling the proper clocks now as well. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* serial: sh-sci: clkdev updates for MSTP gating.Paul Mundt2010-03-101-6/+6
| | | | | | | | | | | | | | | | This fixes up some of the I/D/F clock ambiguity in the sh-sci driver. The interface clock in most cases just wraps back to the peripheral clock, while the function clock wraps in to the MSTP bits. As the logic was somewhat inverted, this cleans that up, and also enables all CPUs with SCI MSTP bits to match function clocks through clkdev lookup. As a result, this gets rid of the clk string abuse on the sh side, and the clock string will be killed off once the ARM code has had a chance to sync up. This also enables MSTP gating on CPUs like 7786 which had never wired it up before. Impacted CPUs are primarily all SH-Mobiles, SH7785, and SH7786. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: introduce struct clk_div4_tableMagnus Damm2010-02-221-1/+5
| | | | | | | | | | This patch introduces struct clk_div4_table. The structure will be used to keep div4 specific data, and is with this patch replacing the struct clk_div_mult_table pointer arg used by the sh_clk_div4_register() functions.

* sh: SH7786 clock framework rewrite.Paul Mundt2010-01-191-96/+88
| | | | | | | | | This rewrites the SH7786 clock framework support completely. It's reworked to provide all of the DIV4 and MSTP function clocks. This brings it in line with the current clock framework code and lets us drop SH7786 from the list of CPUs that require legacy CPG handling. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: clkfwk: Rework legacy CPG clock handling.Paul Mundt2009-05-131-1/+4
| | | | | | | | | 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. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: clkfwk: Use arch_clk_init() for on-chip clock registration.Paul Mundt2009-05-121-2/+1
| | | | | | | | | | | CPUs registering on-chip clocks should be using arch_clk_init() with the new scheme so that the CPUs have the opportunity to establish the topology prior to the initial root clock rate propagation. This ensures that CPUs with on-chip clocks that use CLK_ENABLE_ON_INIT are properly enabled at the initial propagation time, without having to further poke the root clocks. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: clkfwk: Tidy up on-chip clock registration and rate propagation.Paul Mundt2009-05-121-12/+3
| | | | | | | | | | | This tidies up the set_rate hack that the on-chip clocks were abusing to trigger rate propagation, which is now handled generically. Additionally, now that CLK_ENABLE_ON_INIT is wired up where it needs to be for these clocks, the clk_enable() can go away. In some cases this was bumping up the refcount higher than it should have been. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: clkfwk: Consolidate the ALWAYS_ENABLED / NEEDS_INIT mess.Paul Mundt2009-05-121-2/+2
| | | | | | | | | | | | | | | There is no real distinction here in behaviour, either a clock needs to be enabled on initialiation or not. The ALWAYS_ENABLED flag was always intended to only apply to clocks that were physically always on and could simply not be disabled at all from software. Unfortunately over time this was abused and the meaning became a bit blurry. So, we kill off both of all of those paths now, as well as the newer NEEDS_INIT flag, and consolidate on a CLK_ENABLE_ON_INIT. Clocks that need to be enabled on initialization can set this, and it will purposely enable them and bump the refcount up. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: clkfwk: Make recalc return an unsigned long.Paul Mundt2009-05-121-10/+10
| | | | | | | This is prep work for cleaning up some of the rate propagation bits. Trivial conversion. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Add support for SH7786 CPU subtype.Kuninori Morimoto2009-03-031-0/+148
This adds preliminary support for the SH7786 CPU subtype. While this is a dual-core CPU, only UP is supported for now. L2 cache support is likewise not yet implemented.
