| * sh: define DMA slaves per CPU type, remove now redundant headerGuennadi Liakhovetski2010-05-221-2/+1
| | | | | | | | | | | | | | | | | | Now that DMA slave IDs are only used used in platform specific code and have become opaque cookies for the rest of the code, we can make the, CPU specific too.

| * SH: constify multiple DMA related objects and references to themGuennadi Liakhovetski2010-04-261-3/+3
| | | | | | | | | | | | | | | | | | 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.

| * sh: Kill off timer clock strings for legacy CPG parts.Paul Mundt2010-03-291-6/+0
| | | | | | | | | | | | | | Now with the lookup aliases in place there is no longer any need to provide the clock string, kill it off for all legacy CPG CPUs. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * sh: Kill off all timer name clobbering.Paul Mundt2010-03-101-12/+0
| | | | | | | | | | | | | | Now that dev_name() can be used early, we no longer require a static string. Kill off all of the superfluous timer names. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | Separate SH DMA headers into ones, commonly used by both drivers, and ones, specific to each of them. This will make the future development of the dmaengine driver easier.

| * dmaengine: shdma: convert to platform device resourcesGuennadi Liakhovetski2010-03-021-6/+107
| | | | | | | | | | | | | | | | | | | | | | The shdma dmaengine driver currently uses numerous macros to support various platforms, selected by ifdef's. Convert it to use platform device resources and lists of channel descriptors to specify register locations, interrupt numbers and other system-specific configuration variants. Unavoidably, we have to simultaneously convert all shdma users to provide those resources. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * sh: Mass ctrl_in/outX to __raw_read/writeX conversion.Paul Mundt2010-01-261-12/+12
| | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: convert processor device setup functions to arch_initcall()Magnus Damm2009-08-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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().

* | serial: sh-sci: Move SCBRR calculation algo in to platform data.Paul Mundt2009-06-241-0/+2
| | | | | | | | | | | | | | | | This permits each port to select its own SCBRR calculation algorithm, rather than having it all ifdef'ed in the header. There are presently only 5 different variations that all parts fall under. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* | serial: sh-sci: Move SCSCR_INIT in to platform data.Paul Mundt2009-06-241-0/+2
|/ | | | | | | This moves all of the SCSCR_INIT definitions in to the platform data, for future consolidation. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: clkfwk: module_clk -> peripheral_clk rename.Paul Mundt2009-05-131-6/+6
| | | | | | | For consistenct naming, and to allow us to fix up some confusion in the SH-Mobile clock framework, amongst other places. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: TMU platform data for sh7780Magnus Damm2009-05-111-0/+204
| | | | | | | | This patch adds TMU platform data for sh7780. Both clockevent and clocksource support is enabled. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: multiple vectors per irq - sh7780Magnus Damm2009-02-271-67/+30
| | | | | | | | | | | | Update intc tables and platform data to use one linux irq per maskable interrupt source instead of keeping the one-to-one mapping between vectors and linux irqs. This fixes potential irq masking issues for sh7780 hardware blocks such as SCIF/RTC/DMAC/PCIC5/MMCIF/FLCTL/GPIO Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: add interrupt ack code to sh4aYoshihiro Shimoda2008-07-281-3/+8
| | | | | | | | This patch is based on interrupt acknowledge code for external interrupt sources on sh3 processors and adds on sh4a processors. Signed-off-by: Yoshihiro Shimoda <shimoda.yoshihiro@renesas.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* serial: Move asm-sh/sci.h to linux/serial_sci.h.Paul Mundt2008-02-261-1/+1
| | | | | | | | | | | | This header is needed on other architectures as well (namely h8300), which currently fails to build without this in place. Rather than duplicating the port definition completely there, just move this to a common location instead. This should get h8300 working again for 2.6.25, in addition to the changes already pushed by Sato-san in -rc2. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: intc - remove default interrupt priority tablesMagnus Damm2008-01-281-9/+4
| | | | | | | | | | | | | This patch removes interrupt priority tables from the intc code. Optimal priority assignment varies with embedded application anyway, so keeping the interrupt priority tables together with cpu-specific code doesn't make sense. The function intc_set_priority() should be used instead to set the desired interrupt priority level. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: intc - irl mode update for sh7780 and sh7785Magnus Damm2007-09-211-3/+40
| | | | | | | | | | | | | | This patch contains the following fixes and improvements: - Fix address typo for INTMSK2 / INTMSKCLR2 registers on sh7780. - Adds IRQ_MODE_IRLnnnn_MASK using intc controller for IRL masking. - Good old IRQ_MODE_IRLnnnn should not register any intc controller. - plat_irq_setup_pins() now selects IRL or IRQ mode. - the holding function is now disabled using ICR0. By default all external pin interrupts are disabled. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: intc - mark data structures as __initdataMagnus Damm2007-09-211-12/+12
| | | | | | | | | | | With the intc core improved it is now possible to put the intc data structures in the initdata section. Version two of this patch puts the __initdata inside DECLARE_INTC_DESC() and removes the __initdata included in the board specific r2d code.

* sh: intc - add a clear register to struct intc_prio_regMagnus Damm2007-09-211-11/+13
| | | | | | | | We need a secondary register member in struct intc_prio_reg to support dual priority registers used by ipi on x3. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: intc - add support for 7780Magnus Damm2007-07-201-29/+190
| | | | | | | | | | | | | | | | This patch converts the cpu specific 7780 setup code to use the new intc controller. Many new vectors are added and also support for external interrupt sense configuration. So with this patch it is now possible to configure external interrupt pins as edge or level triggered using set_irq_type(). No external interrupts are registered by default. Use plat_irq_setup_pins() to select between IRQ or IRL mode. This patch also fixes the Alarm IRQ for the RTC.

* sh: IPR/INTC2 IRQ setup consolidation.Magnus Damm2007-07-201-1/+1
| | | | | | | | | | This patch unifies the cpu specific interrupt setup functions for interrupt controller blocks such as ipr, intc2 and intc. There is no point in having separate functions for each interrupt controller, so let's clean this up. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* sh: rework intc2 codeMagnus Damm2007-06-151-1/+14
| | | | | | | | | | | | | | | | | | | The shared intc2 code currently contains cpu-specific #ifdefs. This is a tad unclean and it prevents us from using the shared code to drive board-specific irqs on the se7780 board. This patch reworks the intc2 code by moving the base addresses of the intc2 registers into struct intc2_desc. This new structure also contains the name of the controller in struct irq_chip. The idea behind putting struct irq_chip in there is that we can use offsetof() to locate the base addresses in the irq_chip callbacks. One logic change has been made - the original shared intc2 code enabled the interrupts by default but with this patch they are all disabled by default.
