2010-04-26Merge branch 'sh/smp'Paul Mundt
2010-04-26sh: CPU hotplug support for SH-X3 SMP.Paul Mundt
This wires up CPU hotplug for SH-X3 SMP CPUs. Presently only secondary cores can be hotplugged given that the boot CPU has to contend with the broadcast timer. When real local timers are implemented this restriction can be lifted. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-04-26sh: Make sure all SH-X3 cores are populated in the present CPU map.Paul Mundt
This iterates over the maximum number of CPUs we plan to support and makes sure they're all set in the present CPU map. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-04-26SH: constify multiple DMA related objects and references to themGuennadi Liakhovetski
Lists of DMA channels and slaves are not changed, make them constant. Besides, SH7724 channel and slave configuration of both DMA controllers is identical, remove the extra copy of the configuration data. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-04-21sh: Move platform smp ops in to their own structure.Paul Mundt
This cribs the MIPS plat_smp_ops approach for wrapping up the platform ops. This will allow for mixing and matching different ops on the same platform in the future. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-04-15sh: intc: IRQ auto-distribution support.Paul Mundt
This implements support for hardware-managed IRQ balancing as implemented by SH-X3 cores (presently only hooked up for SH7786, but can probably be carried over to other SH-X3 cores, too). CPUs need to specify their distribution register along with the mask definitions, as these follow the same format. Peripheral IRQs that don't opt out of balancing will be automatically distributed at the whim of the hardware block, while each CPU needs to verify whether it is handling the IRQ or not, especially before clearing the mask. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-04-15sh: Disable IRQ balancing for timer and IPI IRQs.Paul Mundt
Make sure that the timer IRQs and IPIs aren't enabled for IRQ balancing. IPIs are disabled as a result of being percpu while the timers simply disable balancing outright. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-04-13sh: intc: userimask support.Paul Mundt
This adds support for hardware-assisted userspace irq masking for special priority levels. Due to the SR.IMASK interactivity, only some platforms implement this in hardware (including but not limited to SH-4A interrupt controllers, and ARM-based SH-Mobile CPUs). Each CPU needs to wire this up on its own, for now only SH7786 is wired up as an example. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-04-13sh: dmaengine support for SH7786 DMAC0.Paul Mundt
Hook up DMAC0 on SH7786. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2010-03-29sh: sh7723 clkdev lookups.Paul Mundt
Convert to TMU clock lookups for SH7723. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-03-29sh: sh7722 clock string death.Paul Mundt
Kills off clock string usage, using the new function clock definition instead. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2010-03-29sh: sh7366 clock string death.Paul Mundt
