* sh: sh4a scif pdata (sh7757/sh7763/sh7770/sh7780/sh7785/sh7786/x3)Magnus Damm2009-12-14
| | | | | | | | | | | | | | | This patch breaks out the sh4a scif serial port platform data from a shared platform device to one platform device per port. Also, add serial ports to the list of early platform devices. All sh4a except SuperH Mobile processors are modified by this patch. While at it, sh7757 gets early platform device support.

* sh: perf events: Add preliminary support for SH-4A counters.Paul Mundt2009-10-28
| | | | | | | | | | | | | | This adds in preliminary support for the SH-4A performance counters. Presently only the first 2 counters are supported, as these are the ones of the most interest to the perf tool and end users. Counter chaining is not presently handled, so these are simply implemented as 32-bit counters. This also establishes a perf event support framework for other hardware counters, which the existing SH-4 oprofile code will migrate over to as the SH-4A support evolves.

* sh: Disable SCIF2 on the SH-X3 proto CPU.Paul Mundt2009-10-18
| | | | | | | | | | | SCIF2 and the FPU exceptions happen to share vector numbers, one in EXPEVT and the other in INTEVT. This is a violation of the interface and should have never made it in to silicon. On top of that, the demux hack that was added for special dispatch is rather error prone, and introduces more problems than it solves. Kill all of it off, and just refuse to deal with SCIF2 outright.

* sh: Force boot CPU in to light sleep mode for SH-X3 SMP.Paul Mundt2009-10-16
| | | | | | | | | All of the secondary CPUs are forced in to light sleep mode, but we were missing the same initialization for the boot CPU. This resulted in inconsistent sleep modes depending on which CPU we were on, confusing the idle loop when not polling. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Reinstate ILSEL -> IRL intc mappings for SH-X3 proto CPU.Paul Mundt2009-10-10
| | | | | | | | | | In the multi-evt conversion for the SH-X3 proto CPU, IRLs were dropped down to a single unique masking source, which ended up blowing up on ILSEL-based IRQs which have special semantics that otherwise confuse the intc code. While this does result in intc spewing about not having a unique masking source, we don't really care. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Runtime PM patch for UIO driver implements coarse grained dynamic power management for UIO devices. With that patch in place we can get rid of the static clock configuration. Which in turn makes it possible for cpuidle to enter deeper sleep.

This saves us from having to do strange ordering things with the broadcast clockevent device, relying on the rating instead. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* sh: convert processor device setup functions to arch_initcall()Magnus Damm2009-07-23
| | | | | | | | | | | | | | | | | | Convert the processor platform device setup functions from __initcall() and sometimes device_initcall() to arch_initcall(). This makes sure that the platform devices are registered a bit earlier so the devices are available when drivers register using initcall levels earlier than device_initcall(). A good example is platform devices needed by i2c-sh_mobile.c which registers a bit earlier using subsys_initcall().

* usb: m66592-udc platform data on_chip supportMagnus Damm2009-07-23
| | | | | | | | | | | | | | | | | | | Convert the m66592-udc driver to use the on_chip flag from platform data to enable on chip behaviour instead of relying on CONFIG_SUPERH_BUILT_IN_M66592 ugliness. This makes the code cleaner and also allows us to support both external and internal m66592 with the same kernel. It also makes the Kconfig part more future proof since we with this patch can add support for new processors with on-chip m66592 without modifying the Kconfig. The patch adds a m66592 header file for platform data and ties in platform data to the existing m66592 devices.
