The INTC hardware block usually contains a rather wide range of features ranging from external IRQ pin handling to legacy interrupt controller support. On older SoCs the INTC is used as a general purpose interrupt controller both for external IRQ pins and on-chip devices. On more recent ARM based SoCs with Cortex-A9 the main interrupt controller is the GIC, but IRQ trigger setup still need to happen in the INTC hardware block. This driver implements the glue code needed to configure IRQ trigger and also handle mask/unmask and demux of external IRQ pins hooked up from the INTC to the GIC. Tested on sh73a0 and r8a7779. The hardware varies quite a bit with SoC model, for instance register width and bitfield widths vary wildly. The driver requires one GIC SPI per external IRQ pin to operate. Each driver instance will handle up to 8 external IRQ pins. The SoCs using this driver are currently mainly used together with regular platform devices so this driver allows configuration via platform data to support things like static interrupt base address. DT support will be added incrementally in the not so distant future.

Wysocki" Date: Wed, 6 Mar 2013 23:46:20 +0100 Subject: ACPI / scan: Add special handler for Intel Lynxpoint LPSS devices Devices on the Intel Lynxpoint Low Power Subsystem (LPSS) have some common features that aren't shared with any other platform devices, including the clock and LTR (Latency Tolerance Reporting) registers. It is better to handle those features in common code than to bother device drivers with doing that (I/O functionality-wise the LPSS devices are generally compatible with other devices that don't have those special registers and may be handled by the same drivers). The clock registers of the LPSS devices are now taken care of by the special clk-x86-lpss driver, but the MMIO mappings used for accessing those registers can also be used for accessing the LTR registers on those devices (LTR support for the Lynxpoint LPSS is going to be added by a subsequent patch). Thus it is convenient to add a special ACPI scan handler for the Lynxpoint LPSS devices that will create the MMIO mappings for accessing the clock (and LTR in the future) registers and will register the LPSS devices' clocks, so the clk-x86-lpss driver will only need to take care of the main Lynxpoint LPSS clock. Introduce a special ACPI scan handler for Intel Lynxpoint LPSS devices as described above. This also reduces overhead related to browsing the ACPI namespace in search of the LPSS devices before the registration of their clocks, removes some LPSS-specific (and somewhat ugly) code from acpi_platform.c and shrinks the overall code size slightly.

The Standard types can operate from -25C to +85C However, beyond that and upto +105C can only be supported by Extended types. Unfortunately, it seems there is no info in MR0(device info) or MR[1,2](device feature) for run time detection of this capability as far as seen on the spec. Hence, we provide a custom_config flag to be populated by platforms which have these "extended" type memories. For the "Standard" memories, we need to consider MR4 notifications of temperature triggers >85C as equivalent to thermal shutdown events (equivalent to Spec specified thermal shutdown events for "extended" parts).

This driver is designed to be reusable between multiple SoCs that share the same basic building block, but so far it has only been used on R-Car H1 (r8a7779). Each driver instance handles 32 GPIOs with individually maskable IRQs. The driver operates on a single I/O memory range and the 32 GPIOs are hooked up a single interrupt. In the case of R-Car H1 either external IRQ pins or GPIOs with interrupts can be used for on-board interupts. For external IRQs 4 pins are supported, and in the case of GPIO there are 202 GPIOS as 202 interrupts hooked up via 6 driver instances and to the GIC and the Cortex-A9 Quad. At this point this driver is interfacing as a regular platform device driver. In the future DT support will be submitted as an incremental feature patch.

The code moved in this patch concerns a group of functions used for decoupling and recoupling the IRQs from the GIC. During sleep and idle the Ux500 system will transfer all IRQ handling to the PRCMU using these functions. Basically we are left with the two alternatives of code placement as: - arch/arm/mach-ux500/pm.c - this because the code is closely related to the GIC, and takes ownership of some of the registers from the PRCMU related to this PM functionality. - drivers/mfd/db8500-prcmu-pm.c - because the code is affecting stuff in the PRCMU register range. But then this code needs to remap and handle GIC registers. This patch implementation is taking the first approach. Currently the cpuidle driver is the only piece of code using this set of functions, but it will later also be used by the suspend/resume code which is currently under review. The header file is moved to: The function prototypes need to be placed in a globally visible header since the CPUidle code is planned to move out to drivers/cpuidle.
