factorise some generic infrastructure to assist looking up struct clks for the ARM & SH architecture. as the code is identical at 99% put the arch specific code for allocation as example in asm/clkdev.h Signed-off-by: NJean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com> Acked-by: NPaul Mundt <lethal@linux-sh.org> Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

This patch converts the remaining sh4-202 clocks to use clkdev for lookup. The now unused name and id from struct clk are also removed. Signed-off-by: NMagnus Damm <damm@opensource.se> Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

The old ctrl in/out routines are non-portable and unsuitable for cross-platform use. While drivers/sh has already been sanitized, there is still quite a lot of code that is not. This converts the arch/sh/ bits over, which permits us to flag the routines as deprecated whilst still building with -Werror for the architecture code, and to ensure that future users are not added.

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: NPaul Mundt <lethal@linux-sh.org>

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.

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: NPaul Mundt <lethal@linux-sh.org>

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: NPaul Mundt <lethal@linux-sh.org>

This is prep work for cleaning up some of the rate propagation bits. Trivial conversion. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

With the SH7722 changes, ->set_rate() also takes an algo_id, SH4-202 was overlooked when this change went in. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

This syncs up the SH clock framework with the linux/clk.h API, for which there were only some minor changes required, namely the clk_get() dev_id and subsequent callsites. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

This adds a relatively simplistic clock framework for sh. The initial goal behind this is to clean up the arch/sh/kernel/time.c mess and to get the CPU subtype-specific frequency setting and calculation code moved somewhere more sensible. This only deals with the core clocks at the moment, though it's trivial for other drivers to define their own clocks as desired.
