2009-08-04sh: clean up MSTPCRn register definitionsMagnus Damm
This patch removes the unused MSTPCRn register definitions from the SuperH Mobile code for sh7722, sh7723 and sh7724. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-08-04sh: hwblk support for sh7724Magnus Damm
This patch adds hwblk support for the sh7724 processor. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-07-23sh: convert processor device setup functions to arch_initcall()Magnus Damm
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().

2009-07-23usb: m66592-udc platform data on_chip supportMagnus Damm
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.

Convert the r8a66597-hcd driver to use the on_chip flag from platform data to enable on chip behaviour instead of relying on CONFIG_SUPERH_ON_CHIP_R8A66597 ugliness. This makes the code cleaner and also allows us to support both external and internal r8a66597 with the same kernel.

2009-07-20sh: hwblk support for sh7723Magnus Damm
This patch adds hwblk support for the sh7723 processor. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-07-20sh: Add support for multiple hwblk countersMagnus Damm
Extend the SuperH hwblk code to support more than one counter. Contains ground work for the future Runtime PM implementation. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-07-05sh: cpuidle for SuperH Mobile using hwblkMagnus Damm
This patch adds cpuidle support for SuperH Mobile. The sleep mode selected by cpuidle is compared with the mode selected by the hwblk sleep code and the best allowed mode is entered. At this point "Sleep mode" and "Sleep mode + SF" are supported. This code can easily be extended to support "Software suspend mode", but the assembly code must first be updated to avoid loosing interrupts. Also, update the code to only copy the assembly snippet into internal memory once at bootup. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-07-05sh: hwblk for sh7722Magnus Damm
This patch contains the sh7722 specific hwblk implementation. Hwblk ids are added to the processor specific header file, module stop bits and areas are kept track of as hwblks, clocks are converted to make use of the shared hwblk code. Code to determine allowed sleep modes is also added. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-07-05sh: hwblk base implementationMagnus Damm
This patch is the hwblk base implementation, containing structures and shared functions dealing with hardware blocks. A each processor model should provide a list of hwblks and describe which module stop bit that is associated with each hwblck and how the hwblks are grouped together into areas. The shared code keeps track of the usage count for each hwblk and the areas. Fallback implementations for processor specific code are also kept as weak symbols. The clock framework, the runtime pm code and cpuidle will all tie into this hwblk implementation. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-06-23sh: SH7786 SMP support.Paul Mundt
SH7786 is roughly identical to SH-X3 proto SMP, though there are only 2 CPUs. This just wraps in to the existing SH-X3 SMP code with some minor changes for SH7786, including wiring up the IPIs properly, enabling IRQ_PER_CPU, and so forth. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2009-06-11sh: Tie sparseirq in to Kconfig.Paul Mundt
Now that the dependent patches are merged, we are ready to enable sparseirq support. This simply adds the Kconfig option, and then converts from the _cpu to the _node allocation routines to follow the upstream sparseirq API changes. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2009-06-11sh: sh7722 clock framework rewriteMagnus Damm
This patch rewrites the sh7722 clock framework code. The new code makes use of the recently merged div4, div6 and mstp32 helper code. Both extal and dll are supported as input clocks to the pll. While at it, now when all SuperH Mobile processors are converted, fix CONFIG_SH_CLK_CPG_LEGACY to depend on CONFIG_ARCH_SHMOBILE.

This patch contains V3 of the sh7724 clock framework rewrite. The new code makes use of the recently merged div4, div6 and mstp32 helper code. Both extal and fll are supported as input clocks to the pll. The div6 clocks are fed through a divide-by-3 block.

2009-06-11sh: rework mode pin codeMagnus Damm
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.

2009-06-11sh: clock div6 helper codeMagnus Damm
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.

2009-06-01sh: Tidy up SH-4A boot_cpu_data.flags probing.Paul Mundt
This tidies up the boot_cpu_data.flags probing on SH-4A. All of them have a few things in common, which we can blindly set, rather than having each subtype have to set the same flags. We can also make assumptions about cache ways and the validity of PTEA, so this also kills off CPU_HAS_PTEA as a config option. There was also a bug in the FPU probing, which is now tidied up. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-06-01sh: Tidy up the optional L2 probing, wire it up for SH7786.Paul Mundt
This tidies up the L2 probing, as it may or may not be implemented on a CPU, regardless of whether it is supported. This converts the cvr validity checks from BUG_ON()'s to simply clearing the CPU_HAS_L2_CACHE flag and moving on with life. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2009-05-22sh: clkfwk: Make clock-cpg usable for non-legacy platforms.Paul Mundt
This adds a new SH_CLK_CPG for parts that have CPG support. SH_CLK_CPG_LEGACY is made to depend on this, and still needs to be set for platforms that want clock-cpg to register the legacy clocks. With this new config item in place, it is now possible to start layering more generic CPG code in place while other platforms transition off of the legacy clocks.

irq_to_desc_alloc_cpu() has been renamed to irq_to_desc_alloc_node() in -next, but as we can not presently enable SPARSE_IRQ without the early irq_desc alloc patch, protect it with an ifdef until the interface has settled and we are ready to enable it system-wide.
