| * | sh: clkfwk: Wire up clk_get_sys() support.Paul Mundt2009-05-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * | sh: clkfwk: Kill off clk_recalc_rate().Paul Mundt2009-05-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Paul Mundt <lethal@linux-sh.org>
| * | sh: clkfwk: Tidy up on-chip clock registration and rate propagation.Paul Mundt2009-05-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Improve the generic clk_set_parent() implementation.Paul Mundt2009-05-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Paul Mundt <lethal@linux-sh.org>
| * | sh: clkfwk: Fix up the clk_enable() error path.Paul Mundt2009-05-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Paul Mundt <lethal@linux-sh.org>
| * | sh: clkfwk: Convert SH-Mobile CPUs to use CLK_ENABLE_ON_INIT.Paul Mundt2009-05-11
| | | | | | | | | | | | | | | | | | | | | Kill off all of the clk_always_enabled leftovers and use the new flag directly. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * | sh: clkfwk: Consolidate the ALWAYS_ENABLED / NEEDS_INIT mess.Paul Mundt2009-05-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: refactor rate propagation.Paul Mundt2009-05-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Paul Mundt <lethal@linux-sh.org>
| * | sh: clkfwk: Add a followparent_recalc() helper.Paul Mundt2009-05-11
| | | | | | | | | | | | | | | | | | | | | | | | This adds a followparent_recalc() helper for clocks that just follow the parent's rate. Switch over the few CPUs that use this scheme for some of their clocks. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * | sh: clkfwk: Make recalc return an unsigned long.Paul Mundt2009-05-11
| | | | | | | | | | | | | | | | | | | | | 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: Wrap irq_to_desc_alloc_cpu() around CONFIG_SPARSE_IRQ temporarily.Paul Mundt2009-05-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | irq_to_desc_alloc_cpu() has been renamed to irq_to_desc_alloc_node() in -next, but as we can not presently enable SPARSE_IRQ without the early irq_desc alloc patch, protect it with an ifdef until the interface has settled and we are ready to enable it system-wide. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* | | sh: irq: Teach ipr and intc about dynamically allocating irq_descs.Paul Mundt2009-05-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This hooks in irq_to_desc_alloc_cpu() to the necessary code paths in the intc and ipr controller registration paths. As these are the primary call paths for all SH CPUs, this alone will make all CPUs sparse IRQ ready. There is the added benefit now that each CPU contains specific IPR and INTC tables, so only the vectors with interrupt sources backing them will ever see an irq_desc instantiation. This effectively packs irq_desc down to match the CPU, rather than padding NR_IRQS out to cover the valid vector range. Boards with extra sources will still have to fiddle with the nr_irqs setting, but they can continue doing so through the machvec as before. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* | | sh: irq: Convert from irq_desc[] to irq_to_desc().Paul Mundt2009-05-21
| | | | | | | | | | | | | | | | | | | | | | | | This converts a few places that were using the old irq_desc[] array over to the shiny new irq_to_desc() helper. Preperatory work for sparse irq support. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* | | sh: irq: Rework the SR.IMASK bitmap handling.Paul Mundt2009-05-21
| | | | | | | | | | | | | | | | | | | | | | | | This tidies up how the SR.IMASK bitmap is managed, using the bitmap API directly instead. At the same time, tidy up the irq_chip conversion a bit. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
