In the case of root clocks (such as clkin oscillators, extal, etc.), the rate information is entirely platform dependent and needs to be lazily set and propagated from the platform code. This provides a method for establishing the rate update on these types of clocks that define no set_rate() op of their own. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

root clocks may simply be placeholders for rate and ancestry information, and have no real associated operations of their own. Account for this, so we are still able to use these sorts of clocks for rate propagation. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

Now with all of the TMU users moved over to the new TMU driver, and the old TMU driver killed off, the left-over infrastructure can go along with it. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

This patch removes the old TMU driver (CONFIG_SH_TMU/timer-tmu.c) As replacement, select the sh_tmu driver with CONFIG_SH_TIMER_TMU and configure timer channel using platform data. If multiple TMU channels are enabled using platform data, use the earlytimer parameter on the kernel command line to select channel. For instance, use "earlytimer=sh_tmu.0" to select the first channel. To verify which timer is being used, look at printouts or the timer irq count in /proc/interrupts.

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 stubs in clk_get_sys() from the ARM clkdev implementation. Tentatively conver the clk_get() lookup code to use this, and once the rest of the in-tree users are happy with this, it can replace the fallback lookups. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

The only user for this is the SH-Mobile r_clk, which is now added as a root clock and can be kicked via propagate_rate() as usual. Given that, there is no longer any need for the special clk_recalc_rate(), so we kill it off. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

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>

This causes the generic clk_set_parent() implementation to be a bit more intelligent. A clk_reparent() is added to move the clock over to the new parent's sibling list, which then allows the generic rate propagation code to succeed. This also becomes a nop if the new and old parents are unchanged. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

There are a couple of instances where a clk_enable() can fail, which the SH-Mobile code presently handles, but doesn't get reported all the way back up. This fixes up the return type so the errors make it all the way down to the drivers. Additionally, we now also error out properly if the parent enable fails. Prep work for aggressively turning off unused clocks on boot. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

Kill off all of the clk_always_enabled leftovers and use the new flag directly. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>
-
由 Paul Mundt 提交于
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 resyncs the rate propagation strategy with the scheme used by the OMAP clock framework. Child clocks are tracked on a list under each parent and propagation happens there specifically rather than constantly iterating over the global clock list. Signed-off-by: NPaul Mundt <lethal@linux-sh.org>
