| * sh: r7785 highlander clock fixesMagnus Damm2009-05-07
| | | | | | | | | | | | | | | | Update the r7785 highlander defconfig to fix PCLK value and that mode4 is set high. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * sh: call clock framework init() callback onceMagnus Damm2009-05-07
| | | | | | | | | | | | | | | | | | Make sure that clk->ops->init() only gets called once in the case of CLK_ALWAYS_ENABLED. Without this patch the init() callback may be called multiple times. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * sh: sh7785 early scif fixMagnus Damm2009-05-07
| | | | | | | | | | | | | | | | | | This patch moves the SH4 case of EARLY_SCIF_CONSOLE_PORT so the SH7785 default value gets used. Without this patch the value for SH7785 is set to 0xffe80000. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| * sh: Integrate the SH-5 onchip_remap() more coherently.Paul Mundt2009-05-07
| | | | | | | | | | | | | | | | | | | | | | Presently this is special-cased for early initialization. While there are situations where these static early initializations are still necessary, with minor changes it is possible to use this for the regular ioremap implementation as well. This allows us to kill off the special-casing for the remap completely and to start tidying up all of the SH-5 special-casing in drivers. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * sh: sh64 still needs ARCH_USES_GETTIMEOFFSET temporarily.Paul Mundt2009-05-07
| | | | | | | | | | | | | | sh64 is still using this, so re-enable it temporarily while SH-5 gets converted to use the generic code. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * sh: Handle shm_align_mask also for HAVE_ARCH_UNMAPPED_AREA_TOPDOWN.Paul Mundt2009-05-07
| | | | | | | | | | | | | | Presently shm_align_mask is only looked at for the bottom up case, but we still want this for proper colouring constraints in the topdown case. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * sh: Flag IRQSTACKS as BROKEN for now.Paul Mundt2009-05-07
| | | | | | | | | | | | | | There still seems to be some stack corruption to sort out here, so flag this as BROKEN until this issue is sorted out. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * sh: Move dummy clockevents broadcast timer to its new home.Paul Mundt2009-05-03
| | | | | | | | | | | | | | | | The old arch/sh/kernel/timers/ directly will be going away completely once the rest of the TMU users are migrated, so move the dummy broadcast driver up a level in preparation. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * sh: Kill off the now unused ARCH_USES_GETTIMEOFFSET code.Paul Mundt2009-05-03
| | | | | | | | | | | | | | | | | | Now that the stragglers (MTU2/CMT/etc.) have been rewritten and we are selecting both GENERIC_TIME and GENERIC_CLOCKEVENTS, the get_offset() timer op is completely unused. As a result, we are now able to kill off the ARCH_USES_GETTIMEOFFSET references. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * sh: select both GENERIC_TIME and GENERIC_CLOCKEVENTS.Paul Mundt2009-05-03
| | | | | | | | | | | | | | Now that the rest of the timers that didn't support clockevents have been rewritten, both of these can be enabled by default. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * sh: Consolidate MTU2/CMT/TMU timer platform data.Paul Mundt2009-05-03
| | | | | | | | | | | | | | | | | | All of the SH timers use a roughly identical structure for platform data, which presently is broken out for each block. Consolidate all of these definitions, as there is no reason for them to be broken out in the first place. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * sh: TMU platform data for sh7722Magnus Damm2009-05-03
| | | | | | | | | | | | | | | | | | This patch adds TMU platform data for sh7722. Only clockevent mode is enabled for now, clocksource requires this patch: "clocksource: setup mult_orig in clocksource_enable()" Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * clocksource: SuperH TMU Timer driverMagnus Damm2009-05-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a TMU driver for the SuperH architecture. The TMU driver is a platform driver with early platform support to allow using a TMU channel as clockevent or clocksource during system bootup or later. Clocksource or clockevent can be selected. Both periodic and oneshot clockevents are supported. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * sh: remove old MTU2 driverMagnus Damm2009-05-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes the old MTU2 driver (CONFIG_SH_MTU2/timer-mtu2.c) As replacement, select the sh_cmt driver with CONFIG_SH_TIMER_MTU2 and configure timer channel using platform data. If multiple MTU channels are enabled using platform data, use the earlytimer parameter on the kernel command line to select channel. For instance, use "earlytimer=sh_mtu2.0" to select the first channel. To verify which timer is being used, look at printouts or the timer irq count in /proc/interrupts.

| * clocksource: SuperH MTU2 Timer driverMagnus Damm2009-05-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a MTU2 driver for the SuperH architecture. The MTU2 driver is a platform driver with early platform support to allow using a MTU2 channel as only clockevent during system bootup. Clocksource on sh2a is currently unsupported due to code generation issues with 64-bit math, so at this point only periodic clockevent support is in place.

| * | sh: pass through ioremap() for non-mmu processors.Magnus Damm2009-04-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All 32-bit SuperH processors currently go through __ioremap_mode() and check for IO_TRAPPED and directly mapped segments. With this patch we simplify the MMU less case with a pass through version of __ioremap_mode() which just returns the physical address. The effects of this is change are: - fix non-MMU ioremap() of high address hardware blocks (sh7203 CMT) - make sure IO_TRAPPED is not selected Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * | sh: register the rtc-generic platform device properly.Paul Mundt2009-04-28
| | | | | | | | | | | | | | | | | | | | | | | | The device registration was accidentally omitted, add it back in. Do some basic device probing as well, so this doesn't show up for platforms that tie in to the RTC interface properly. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| * | sh: setup timers in late_time_init()Magnus Damm2009-04-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch moves the SuperH timer setup code from time_init() to late_time_init(). Good things about this change: - interrupts: they are enabled at late_time_init() - mm: regular kmalloc() can be used at late_time_init() Together with moving to late_time_init() this patch changes the sh_cmt driver to always allocate with kmalloc(). This simplifies the code a bit and also fixes section mismatches. Signed-off-by: Magnus Damm <damm@igel.co.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The RTS7751R2D_1 boards only support 1MB of socket-mounted MBM29F040 flash, which we just leave alone as it's not terribly interesting. This adds support for the s29gl256p on the r2d+ boards that makes a bit more sense to expose to the user.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This follows the similar sort of scheme that the refactored SH7780 code uses, using a 64MB CS3 mapping to handle the window0 case, and simply discarding window1. This vastly simplifies the code, and allows most of the board-specific setup to go die. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
