2015-02-24ARM: shmobile: sh7372: Remove Legacy C SoC codeMagnus Damm1-672/+0
Remove support for the legacy Cortex-A8 based sh7372 SoC. The Linux kernel still lacks DT bindings for the sh7372 INTC interrupt controller so DT multiplatform support is not possibile. Also, the sh7372 SoC never went into mass production anyway so to aid migration to DT multiplatform simply get rid of sh7372 support.

2014-10-27ARM: shmobile: Remove FSF address from copyright headersLaurent Pinchart1-4/+0
The information is already included in the COPYING file in the kernel sources root directory, we don't want to modify all source files when the FSF will move to a new address, and I'm tired of seeing the related checkpatch.pl warnings.

2014-06-17ARM: shmobile: Move most of irqs.h, keep some for pinctlMagnus Damm1-1/+1
Move most of irqs.h so it can be used as #include "irqs.h" instead of the old style #include <mach/irqs.h>. Legacy code in drivers/pinctrl needs more work to get rid of the "mach" portion of the include path, so some part is left in the original location.

2012-09-18ARM: shmobile: use __iomem pointers for MMIOArnd Bergmann1-12/+15
ARM is moving to stricter checks on readl/write functions, so we need to use the correct types everywhere. This patch is a bit ugly for shmobile, which is the only platform that just uses integer literals all over the place, but I can't see a better way to do this.

2012-04-11ARM: mach-shmobile: Rework sh7372 INTCS demuxer V2Magnus Damm1-9/+14
This patch is the sh7372 INTC demux rework V2. Updates the sh7372 INTCS demuxer to not hook into the INTCA interrupt controller. The mask register for the chained INTCS interrupt source happens to be located in the INTCS register range instead of the INTCA as expected. To allow each INTCA and INTCS interrupt controller to work in their own IRQ range this patch moves the INTCS vector away. Needed for future IRQ domain support.

2012-04-11ARM: mach-shmobile: Use INTC_IRQ_PINS_16H on sh7372Magnus Damm1-3/+8
Use INTC_IRQ_PINS_16H on sh7372 to have two separate interrupt controllers for the external IRQ pins. This is preparation work for future IRQ domain support. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
2012-01-26ARM: shmobile: remove NR_IRQSRob Herring1-0/+1
Remove NR_IRQS and explicitly include mach/irqs.h as needed. shmobile properly allocates irq_descs for each irqchip, so setting .nr_irqs for each machine is not needed. Signed-off-by: Rob Herring <rob.herring@calxeda.com>
2011-12-26PM / shmobile: Don't include SH7372's INTCS in syscore suspend/resumeRafael J. Wysocki1-0/+1
Since the SH7372's INTCS in included into syscore suspend/resume, which causes the chip to be accessed when PM domains have been turned off during system suspend, the A4R domain containing the INTCS has to stay on during system sleep, which is suboptimal from the power consumption point of view. For this reason, add a new INTC flag, skip_syscore_suspend, to mark the INTCS for intc_suspend() and intc_resume(), so that they don't touch it. This allows the A4R domain to be turned off during system suspend and the INTCS state is resrored during system resume by the A4R's "power on" code.

2011-12-26PM / shmobile: Add support for the sh7372 A4S power domain / sleep modeMagnus Damm1-0/+49
The sh7372 contains a power domain named A4S which in turn contains power domains for both I/O Devices and CPU cores. At this point only System wide Suspend-to-RAM is supported, but the the hardware can also support CPUIdle. With more efforts in the future CPUIdle can work with bot A4S and A3SM. Tested on the sh7372 Mackerel board. [rjw: Rebased on top of the current linux-pm tree.] Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Rafael J. Wysocki <rjw@sisk.pl>
2011-11-04ARM: mach-shmobile: Use common INTC IRQ code on sh7372Magnus Damm1-64/+8

2011-10-22ARM: mach-shmobile: sh7372 A4R support (v4)Magnus Damm1-1/+51
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>
2011-08-29ARM: mach-shmobile: Remove 3DG/SGX from sh7372 INTCSMagnus Damm1-4/+3
This patch removes support for the SGX interrupt source in the sh7372 INTCS controller. The SGX hardware block included in sh7372 is already hooked up to the ARM Cortex-A8 core using the INTCA controller, so SGX users are encouraged to make use of that interrupt source instead. Removing support for the SGX interrupt source in INTCS simplifies the sh7372 power management code by allowing us to assume that only INTCA needs to be powered on to operate the SGX hardware. If the INTCS interrupt source would be kept then the kernel would be forced to deal with additional dependencies that does not follow the regular power domain hiearachy. With this patch in place we can safely power down INTCS while the SGX is operating. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2011-05-24ARM: arch-shmobile: Use multiple irq vectors for SDHISimon Horman1-23/+23
This patch reverts "ARM: mach-shmobile: sh7372 SDHI vector merge" and supplies 3 IRQ resources for each SDHI block. Some blocks have a 4th IRQ, but this is used for DRM feathres that I do not have access tot he documentation for and are almost certainly tainted by licensing issues. So the 4th IRQ is not hooked-up even if it exists.

2010-05-20ARM: mach-shmobile: sh7372 INTCS supportMagnus Damm1-0/+220
Add support for the sh7372 INTCS interrupt controller. INTCS is the interrupt controller for the sh7372 SuperH processor core. It is tied into the INTCA interrupt controller which interfaces to the ARM processor. INTCS support is implemented using a new INTC table together with a chained interrupt handler that ties into the already supported INTCA controller.
