* ARM: mach-shmobile: sh73a0 PINT IRQ base fixMagnus Damm2012-01-17
| | | | | | | | | | | Bump up the sh73a0 PINT IRQ base from 768 to 800 to avoid collision with INTCS vectors for IRQ16->IRQ32 at 0x3xxx. Without this fix the sh73a0 IRQ pin handling code collides with the PINT code which results in hangs on Kota2 during boot.

* ARM: mach-shmobile: r8a7779 SMP support V3Magnus Damm2012-01-11
| | | | | | | | | | | | | | | | | | | | | This patch contains r8a7779 SMP support V3 - now including CPU hotplug offine and online support. The r8a7779 power domain code is tied together with SMP glue code which allows us to control the power domains via CPU hotplug. At this point the kernel boots with the 4 Cortex-A9 cores in SMP mode and all CPU cores except CPU0 can be hotplugged. The code in platsmp.c is quite far from pretty, but it is kept like that intentionally to avoid creating layers of code that will go away in the near future anyway. The code needs to be updated when some per-SoC handling code will be added to the ARM architecture, see the following patch for more information: "[RFC PATCH 0/3] Per SoC descriptor" Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
* ARM: mach-shmobile: r8a7779 power domain support V2Magnus Damm2012-01-10
| | | | | | | | | | | | | | Add power domain control support for the r8a7779 SoC V2. This adds support for 4 power domains for I/O Devices together with code that can be used for CPU cores as well. The only out of the ordinary experience is the need for ioremap() of SYSC registers. Because of that we need to execute some init function before setting up the domains.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Initial support for the r8a7779 SoC and the Marzen board (V2). Only SCIF ports and the TMU are supported at this point. To keep things simple only entity-mapped virt-to-phys mappings are supported. This forces drivers and other SoC glue code to make use of ioremap(). We cannot support early serial console due to virtual address space collisions with the ARM kernel. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>

| | * | PM / shmobile: Remove the stay_on flag from SH7372's PM domainsRafael J. Wysocki2011-12-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SH7372 uses two independent mechanisms for ensuring that power domains will never be turned off: the stay_on flag and the "always on" domain governor. Moreover, the "always on" governor is only taken into accout by runtime PM code paths, while the stay_on flag affects all attempts to turn the given domain off. Thus setting the stay_on flag causes the "always on" governor to be unnecessary, which is quite confusing. However, the stay_on flag is currently only set for two domains: A3SP and A4S. Moreover, it only is set for the A3SP domain if console_suspend_enabled is set, so stay_on won't be necessary for that domain any more if console_suspend_enabled is checked directly in its .suspend() routine. [This requires domain .suspend() to return a result, but that is a minor modification.] Analogously, stay_on won't be necessary for the A4S domain if it's .suspend() routine always returns an error code.

It turns out nobody is using that particular feature as both PXA and shmobile have all their machine descriptors populated with the interrupt handler, leaving unused code (or empty macros) in their entry-macro.S file just to be able to compile entry-armv.S. Make CONFIG_MULTI_IRQ_HANDLER exclusive wrt arch_irq_handler_default, which allows to remove one test from the hot path. Also cleanup both PXA and shmobile entry-macro.S.

Provide a new function (soft_restart()) which does the setup and final call for this, and make platforms use it. Eliminate the call to setup_restart() from the default handler. This means that platforms arch_reset() function is no longer called with the page tables prepared for a soft-restart, and caches will still be enabled.

This is basically the include of asm-generic/gpio.h and the definition of gpio_get_value, gpio_set_value, and gpio_cansleep as described in Documentation/gpio.txt Acked-by: H Hartley Sweeten <hsweeten@visionengravers.com> Tested-by: David Brown <davidb@codeaurora.org> Acked-by: David Brown <davidb@codeaurora.org> Tested-by: Linus Walleij <linus.walleij@linaro.org> Acked-by: Kukjin Kim <kgene.kim@samsung.com> Tested-by: Shawn Guo <shawn.guo@linaro.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
| * | | ARM: mach-shmobile: sh7372 A4R support (v4)Magnus Damm2011-10-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change adds support for the sh7372 A4R power domain. The sh7372 A4R hardware power domain contains the SH CPU Core and a set of I/O devices including multimedia accelerators and I2C controllers. One special case about A4R is the INTCS interrupt controller that needs to be saved and restored to keep working as expected. Also the LCDC hardware blocks are in a different hardware power domain but have their IRQs routed only through INTCS. So as long as LCDCs are active we cannot power down INTCS because that would risk losing interrupts. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change adds support for the sh7372 A3SP power domain. The sh7372 A3SP hardware power domain contains a wide range of I/O devices. The list of I/O devices include SCIF serial ports, DMA Engine hardware, SD and MMC controller hardware, USB controllers and I2C master controllers. This patch adds the A3SP low level code which powers the hardware power domain on and off. It also ties in platform devices to the pm domain support code. It is worth noting that the serial console is hooked up to SCIFA0 on most sh7372 boards, and the SCIFA0 port is included in the A3SP hardware power domain. For this reason we cannot output debug messages from the low level power control code in the case of A3SP. QoS support is needed in drivers before we can enable the A3SP power control on the fly.

The sh7372 A3SM hardware power domain contains the ARM Cortex-A8 CPU Core including L2 cache. This sleep mode can be seen as a one step deeper sleep mode from the already existing Core Standby mode. To wake up from A3SM sleep only a few wakeup sources are supported - so the regular INTC controller will not be able to help us unfortunately. The code in this patch will enter A3SM sleep via the regular Suspend-to-RAM interface in the case of only wakeups supported by A3SM are enabled. If unsupported wakeups are enabled then Core Standby will be used instead. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>

| * | ARM: 6886/1: mmc, Add zboot from eSD support for SuperH Mobile ARMSimon Horman2011-06-29
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This allows a ROM-able zImage to be written to eSD and for SuperH Mobile ARM to boot directly from the SDHI hardware block. This is achieved by the MaskROM loading the first portion of the image into MERAM and then jumping to it. This portion contains loader code which copies the entire image to SDRAM and jumps to it. From there the zImage boot code proceeds as normal, uncompressing the image into its final location and then jumping to it.
