* sh: intc: Kill off special reservation interface.Paul Mundt2012-05-221-8/+0
| | | | | | | | | | | | | | | | At present reserving the IRLs in the IRQ bitmap in addition to the dropping of the legacy IRQ pre-allocation prevent IRL IRQs from being allocated for the x3proto board. The only reason to permit reservations was to lock down possible hardware vectors prior to dynamic IRQ scanning, but this doesn't matter much given that the hardware controller configuration is sorted before we get around to doing any dynamic IRQ allocation anyways. Beyond that, all of the tables are __init annotated, so quite a bit more work would need to be done to support reconfiguring things like IRL controllers on the fly, much more than would ever make it worth the hassle.

* sh: clkfwk: Support variable size accesses for div4/div6 clocks.Paul Mundt2012-04-121-34/+37
| | | | | | | | This follows the MSTP clock change and implements variable access size support for the rest of the CPG clocks, too. Upcoming SH-2A support has need of this for 16-bit div4 clocks, while others will follow. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: clkfwk: Support variable size accesses for MSTP clocks.Paul Mundt2012-04-111-11/+27
| | | | | | | | | The bulk of the MSTP users require 32-bit access, but this isn't the case for some of the SH-2A parts, so add in some basic infrastructure to let the CPU define its required access size in preparation.

For this reason, add a new INTC flag, skip_syscore_suspend, to mark the INTCS for intc_suspend() and intc_resume(), so that they don't touch it. This allows the A4R domain to be turned off during system suspend and the INTCS state is resrored during system resume by the A4R's "power on" code.

The PFC main data structure gets updated with a pointer to a struct resources array that point out all register windows used by the PFC instance. The register definitions are kept as physical addresses but the PFC code will do transparent conversion into virtual addresses whenever register windows are specified using with struct resource. To introduce as little performance penalty as possible the virtual address of each data register is cached in memory. The virtual address of each configuration register is however calculated during run time. This because the configuration is considered slow path so focus is instead put on keeping memory foot print as small as possible. The PFC register access code is in this patch updated from __raw_readN() / __raw_writeN() into ioreadN() / iowriteN(). This patch is needed to support the PFC block in r8a7779.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that all of the named string association with clocks has been migrated to clkdev lookups there's no meaningful named topology that can be constructed for a debugfs tree view. Get rid of the left over bits, and shrink struct clk a bit in the process. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| * | drivers: sh: Generalize runtime PM platform stub.Paul Mundt2011-11-112-0/+75
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The runtime PM platform support stub in use by ARM-based SH/R-Mobile platforms contains nothing that's specifically ARM-related and instead of wholly generic to anything using the clock framework. The recent runtime PM changes interact rather badly with the lazy disabling of clocks late in the boot process through the clock framework, leading to situations where the runtime suspend/resume paths are entered without a clock being actively driven due to having been lazily gated off. In order to correct this we can trivially tie in the aforementioned stub as a general fallback for all SH platforms that don't presently have their own runtime PM implementations (the corner case being SH-based SH-Mobile platforms, which have their own stub through the hwblk API -- which in turn has bitrotted and will be subsequently adapted to use the same stub as everyone else), regardless of whether the platforms choose to define power domains of their own or not. This fixes up regressions for clock framework users who also build in runtime PM support without any specific power domains of their own, which was previously causing the serial console to be lost when warring with lazy clock disabling.
