| * sh: Kill off the remnants of the old timer code.Paul Mundt2009-05-12
| | | | | | | | | | | | | | | | 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: Paul Mundt <lethal@linux-sh.org>
| * sh: remove old TMU driverMagnus Damm2009-05-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | sh: clkfwk: Use arch_clk_init() for on-chip clock registration.Paul Mundt2009-05-12
| | | | | | | | | | | | | | | | | | | | | | 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: Handle clk_get_sys() returning an ERR_PTR.Paul Mundt2009-05-12
| | | | | | | | | | | | | | clk_get() needs to also perform an IS_ERR() check to see whether clk_get_sys() failed or not. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* | 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. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* | 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.

* | 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

* sh: multiple vectors per irq - sh7760Magnus Damm2009-05-11
| | | | | | | | | | | | Update intc tables and platform data to use one linux irq per maskable interrupt source instead of keeping the one-to-one mapping between vectors and linux irqs.

* sh: Fix up R0 dependence in __arch_swab16/32.Paul Mundt2009-05-10
| | | | | | | | | | | | | | | | | | | | | | | There is nothing in these routines that inherently depends on R0 use. Given that these routines are inlined, it is rather easy to blow up the compiler by exhausting the spill class when performing a 64-bit swab. This presently manifests itself as the following: CC fs/ocfs2/suballoc.o fs/ocfs2/suballoc.c: In function 'ocfs2_reserve_suballoc_bits': fs/ocfs2/suballoc.c:638: error: unrecognizable insn: (insn 2793 1230 1231 103 arch/sh/include/asm/swab.h:33 (set (reg:HI 853) (subreg:HI (reg:SI 149 macl) 2)) -1 (expr_list:REG_DEAD (reg:SI 149 macl) (nil))) fs/ocfs2/suballoc.c:638: internal compiler error: in extract_insn, at recog.c:1991 This patch switches over to using an arbitrarily assigned register instead.
