| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Makes code futureproof against the impending change to mm->cpu_vm_mask. It's also a chance to use the new cpumask_ ops which take a pointer (the older ones are deprecated, but there's no hurry for arch code).

* | | kmap_types: make most arches use generic header fileRandy Dunlap2009-06-16
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Convert most arches to use asm-generic/kmap_types.h. Move the KM_FENCE_ macro additions into asm-generic/kmap_types.h, controlled by __WITH_KM_FENCE from each arch's kmap_types.h file. Would be nice to be able to add custom KM_types per arch, but I don't yet see a nice, clean way to do that. Built on x86_64, i386, mips, sparc, alpha(tonyb), powerpc(tonyb), and 68k(tonyb). Note: avr32 should be able to remove KM_PTE2 (since it's not used) and then just use the generic kmap_types.h file. Get avr32 maintainer approval.

| * sh: rework mode pin codeMagnus Damm2009-06-11
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch reworks the mode pin code to keep the pin definitions in one place. The mode pins values are now the value of the bit instead of bit number. With this patch in place the sh7785 header file contains mode pin comments. The sh7785 clock code and the sh7785lcr board code are updated to reflect the new shared mode pins. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * sh: clock div6 helper codeMagnus Damm2009-06-11
| | | | | | | | | | | | | | | | | | | | | | | | This patch adds div6 clock helper code. The div6 clocks are simply 6-bit divide-by-n modules where n is 1 to 64. Needed for vclk on sh7722, sh7723, sh7343 and sh7366. sh7724 needs this even more for vclk, fclka, fclkb, irdaclk and spuclk.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes the 16-bit case of the sh4a specific unaligned access implementation. Without this patch the 16-bit version of sh4a get_unaligned() results in a 32-bit read which may read more data than intended and/or cross page boundaries. Unbreaks mtd NOR write handling on Migo-R.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add mode pin support for the SuperH architecture V2. With this patch applied the board code can add their own function to export the cpu mode pin configuration. In most cases this will be a constant bitmap, but boards that allow reading this from a register can instead read out the pin state from hardware.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adopts the OMAP clock framework debugfs bits and replaces the aging procfs bits. The procfs clocks entry was primarily a debugging aid, and used to be tied in to cpuinfo before the clock list grew too unweildly. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| | * | sh: clkfwk: rate table construction and rounding for SH7785.Paul Mundt2009-05-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for constructing a rate table by looking at potential divisors for a specified clock. Each FQRMR clock is given its own table. Presently each table is rebuilt when the parent propagates down a new rate, so some more logic needs to be added to do this more intelligently. Additionally, a fairly generic round_rate() implementation is then layered on top of it, which subsequently provides us with cpufreq support. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| | * | sh: clkfwk: Update SH7785 for refactored clock framework.Paul Mundt2009-05-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This updates the SH7785 CPU code as well as the SH7785LCR board support code for making use of the newly refactored clock framework. Support for the legacy CPG clocks is dropped at this point, with the extal frequency fed in from the board code. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| | * | sh: clkfwk: Rework legacy CPG clock handling.Paul Mundt2009-05-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Improve the generic clk_set_parent() implementation.Paul Mundt2009-05-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Mundt2009-05-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Consolidate the ALWAYS_ENABLED / NEEDS_INIT mess.Paul Mundt2009-05-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Mundt2009-05-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This resyncs the rate propagation strategy with the scheme used by the OMAP clock framework.
