| | * of/mips: Cleanup some include directives/files.David Daney2010-10-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The __init directives should go on the definitions of things, not the declaration, also __init is meaningless for inline functions, so remove it from prom.h. This allows us to get rid of a useless #include, but most of the rest of them are useless too, so kill them as well. If of_i2c.c needs irq definitions, it should include linux/irq.h directly, not assume indirect inclusion via asm/prom.h.

| | * of/flattree: Eliminate need to provide early_init_dt_scan_chosen_archGrant Likely2010-10-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch refactors the early init parsing of the chosen node so that architectures aren't forced to provide an empty implementation of early_init_dt_scan_chosen_arch. Instead, if an architecture wants to do something different, it can either use a wrapper function around early_init_dt_scan_chosen(), or it can replace it altogether. This patch was written in preparation to adding device tree support to both x86 ad MIPS. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Tested-by: David Daney <ddaney@caviumnetworks.com>
| | * of/device: Rework to use common platform_device_alloc() for allocating devicesGrant Likely2010-10-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current code allocates and manages platform_devices created from the device tree manually. It also uses an unsafe shortcut for allocating the platform_device and the resource table at the same time. (which I added in the last rework; sorry). This patch refactors the code to use platform_device_alloc() for allocating new devices. This reduces the amount of custom code implemented by of_platform, eliminates the unsafe alloc trick, and has the side benefit of letting the platform_bus code manage freeing the device data and resources when the device is freed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rather than assuming an architecture defines prom_getchild and friends, define an ops struct with hooks for the various prom functions that pdt.c needs. This ops struct is filled in by the arch-(and sometimes firmware-)specific code, and passed to of_pdt_build_devicetree. Update sparc code to define the ops struct as well.

A simple alloc/free interface is provided (lifed from avr32) for generic code.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The SDK7786 FPGA has secondary control over the PCIe clocks, specifically relating to the slots and oscillator. This ties the FPGA clocks in to the clock framework and balances the refcounting similar to how the primary on-chip clocks are managed. While the on-chip clocks are per-port, the FPGA clock enable/disable is global for the entire block. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

By default the vertical slot 3 on the baseboard is enabled, so this adds in a command line option for forcibly enabling the slot 4 edge connector. If nothing has been specified on the command line, we fall back to reading the resistor values for card presence to figure out where to route the port to.

This introduces the concept of IRQ subgroups in the intc core, where a virtual IRQ map is constructed for each of the pre-defined cause bits, and a higher level chained handler takes control of the parent INTEVT. This enables CPUs with heavily muxed IRQ vectors (especially across disjoint blocks) to break things out in to a series of managed chained handlers while being able to dynamically lookup and adopt the IRQs created for them. This is largely an opt-in interface, requiring CPUs to manually submit IRQs for subgroup splitting, in addition to providing identifiers in their enum maps that can be used for lazy lookup via the radix tree.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some controllers will need to be initialized lazily due to pinmux constraints, while others may simply have no need to be brought online if there are no backing devices for them attached. In this case it's still necessary to be able to reserve their hardware vector map before dynamic IRQs get a hold of them. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| | * | | sh: Handle pinmux for SH-X3 proto IRQ/IRL modes.Paul Mundt2010-10-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The SH-X3 proto CPU has all of the external IRQ and IRL pins muxed, make sure that we're able to grab them before attempting to register their respective IRQ controllers. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| | * | | sh: pinmux support for SH-X3 proto CPUs.Paul Mundt2010-10-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds in support for GPIO/pinmux on the SH-X3 proto CPUs. This will subsequently be used by the x3proto board. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| | * | | sh: Support IRQ balancing for SH-X3 proto cores, too.Paul Mundt2010-10-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds in hardware IRQ auto-distribution support for SH-X3 proto CPUs, following the SH7786 support. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| | * | | sh: Support userimask for all SH-X3 interrupt controllers.Paul Mundt2010-10-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This shuffles some of the shared bits out of the 7786 code and in to a shared SH-X3 support file. Presently just for userimask, but also a good place for the IRQ balancing wrappers. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| | * | | sh: Update SH-X3 subtype for clkdev lookups.Paul Mundt2010-10-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rewrite the SH-X3 proto CPU clock framework for clkdev. Signed-off-by: Paul Mundt <lethal@linux-sh.org>
| | * | | sh: boot kernel with SR.BL setMagnus Damm2010-09-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Update the SH kernel to keep SR.BL set until the VBR register has been initialized. Useful to allow boot of the kernel even though exceptions are pending. Without this patch there is a window of time when exceptions such as NMI are enabled but no exception handlers are installed. This patch modifies both the zImage loader and the actual kernel to boot with BL=1, but the zImage loader is modfied in such a way that the init_sr value is unchanged to not break the zImage loader provided by kexec. Tested on sh7724 Ecovec and on the SH4AL-DSP core included in sh7372. Signed-off-by: Magnus Damm <damm@opensource.se> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
