* sh: always enable sh7724 vpu_clk and set to 166MHz on EcovecMagnus Damm2010-02-22
| | | | | | | | | | | | | Update the sh7724 processor code to always enable vpu_clk. On the Ecovec board, set the vpu_clk to 166 Mhz. The 166MHz setting results in a divide-by-6 setup for vpu_clk and improves the VPU performance compared to the power-on-reset/bootloader configuration.

* sh: add sh7724 kick callback to clk_div4_tableMagnus Damm2010-02-22
| | | | | | | | | | | This patch adds a ->kick() callback to clk_div4_table and ties it into sh_clk_div4_set_rate(). A sh7724 specific kick function is also added that updates the KICK bit whenever div4 clocks in FRQCRA and FRQCRB have been set. Allows us to set the VPU clock.

* sh: introduce struct clk_div4_tableMagnus Damm2010-02-22
| | | | | | | | | | This patch introduces struct clk_div4_table. The structure will be used to keep div4 specific data, and is with this patch replacing the struct clk_div_mult_table pointer arg used by the sh_clk_div4_register() functions.

* sh: fix sh7723 SDHI support using INTC force_disableMagnus Damm2010-02-16
| | | | | | | | | | | Update the sh7723 INTC tables with force_enable support to mask out pending unsupported SDHI interrupt sources.

* sh: Mass ctrl_in/outX to __raw_read/writeX conversion.Paul Mundt2010-01-25
| | | | | | | | | | | The old ctrl in/out routines are non-portable and unsuitable for cross-platform use. While drivers/sh has already been sanitized, there is still quite a lot of code that is not. This converts the arch/sh/ bits over, which permits us to flag the routines as deprecated whilst still building with -Werror for the architecture code, and to ensure that future users are not added.

* sh: Kill off the special uncached section and fixmap.Paul Mundt2010-01-21

* sh: support SIU sourcing from external clock on sh7722Guennadi Liakhovetski2010-01-19
| | | | | | | | | | Implement .set_rate() for all SH "div4 clocks," .enable(), .disable(), and .set_parent() for those, that support them. This allows, among other uses, reparenting of SIU clocks to the external source, and enabling and disabling of the IrDA clock on sh7722.

* sh: SH7786 clock framework rewrite.Paul Mundt2010-01-19
| | | | | | | | | This rewrites the SH7786 clock framework support completely. It's reworked to provide all of the DIV4 and MSTP function clocks. This brings it in line with the current clock framework code and lets us drop SH7786 from the list of CPUs that require legacy CPG handling. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Fix up the secondary CPU entry point for 32bit mode.Paul Mundt2010-01-15
| | | | | | | | Presently the secondary CPU entry point is only aimed at 29bit phys mode, causing it to point to a stray virtual address in 32bit mode. Fix it up after consulting with our shiny new __in_29bit_mode(). Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: Abstracted SH-4A UBC support on hw-breakpoint core.Paul Mundt2010-01-05
| | | | | | | | | | | | | | | | | | | | | This is the next big chunk of hw_breakpoint support. This decouples the SH-4A support from the core and moves it out in to its own stub, following many of the conventions established with the perf events layering. In addition to extending SH-4A support to encapsulate the remainder of the UBC channels, clock framework support for handling the UBC interface clock is added as well, allowing for dynamic clock gating. This also fixes up a regression introduced by the SIGTRAP handling that broke the ksym_tracer, to the extent that the current support works well with all of the ksym_tracer/ptrace/kgdb. The kprobes singlestep code will follow in turn. With this in place, the remaining UBC variants (SH-2A and SH-4) can now be trivially plugged in. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

* 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.

* 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>
