2014-11-23PCI/MSI: Provide mechanism to alloc/free MSI/MSIX interrupt from irqdomainJiang Liu
Provide mechanism to directly alloc/free MSI/MSIX interrupt from irqdomain, which will be used to replace arch_setup_msi_irq()/ arch_setup_msi_irqs()/arch_teardown_msi_irq()/arch_teardown_msi_irqs(). To kill weak functions, this patch introduce a new weak function arch_get_pci_msi_domain(), which is to retrieve the MSI irqdomain for a PCI device. This weak function could be killed once we get a common way to associate MSI domain with PCI device.

2014-11-23asm-generic: Add msi.hThomas Gleixner
To support MSI irq domains we want a generic data structure for allocation, but we need the option to provide an architecture specific version of it. So instead of playing #ifdef games in linux/msi.h we add a generic header file and let architectures decide whether to include it or to provide their own implementation and provide the required typedef. I know that typedefs are not really nice, but in this case there are no forward declarations required and it's the simplest solution.

2014-11-23genirq: Work around __irq_set_handler vs stacked domains ordering issuesMarc Zyngier
With the introduction of stacked domains, we have the issue that, depending on where in the stack this is called, __irq_set_handler will succeed or fail: If this is called from the inner irqchip, __irq_set_handler() will fail, as it will look at the outer domain as the (desc->irq_data.chip == &no_irq_chip) test fails (we haven't set the top level yet). This patch implements the following: "If there is at least one valid irqchip in the domain, it will probably sort itself out". This is clearly not ideal, but it is far less confusing then crashing because the top-level domain is not up yet.

2014-11-23irqdomain: Introduce new interfaces to support hierarchy irqdomainsJiang Liu
We plan to use hierarchy irqdomain to suppport CPU vector assignment, interrupt remapping controller, IO-APIC controller, MSI interrupt and hypertransport interrupt etc on x86 platforms. So extend irqdomain interfaces to support hierarchy irqdomain. There are already many clients of current irqdomain interfaces. To minimize the changes, we choose to introduce new version 2 interfaces to support hierarchy instead of extending existing irqdomain interfaces. According to Thomas's suggestion, the most important design decision is to build hierarchy struct irq_data to support hierarchy irqdomain, so hierarchy irqdomain related data could be saved in struct irq_data. With support of hierarchy irq_data, we could also support stacked irq_chips. This is most useful in case of set_affinity(). The new hierarchy irqdomain introduces following interfaces: 1) irq_domain_alloc_irqs()/irq_domain_free_irqs(): allocate/release IRQ and related resources. 2) __irq_domain_alloc_irqs(): a special version to support legacy IRQs. 3) irq_domain_activate_irq()/irq_domain_deactivate_irq(): program interrupt controllers to activate/deactivate interrupt. There are also several help functions to ease irqdomain implemenations: 1) irq_domain_get_irq_data(): get irq_data associated with a specific irqdomain. 2) irq_domain_set_hwirq_and_chip(): save irqdomain specific data into irq_data. 3) irq_domain_alloc_irqs_parent()/irq_domain_free_irqs_parent(): invoke parent irqdomain's alloc/free callbacks. We also changed irq_startup()/irq_shutdown() to invoke irq_domain_activate_irq()/irq_domain_deactivate_irq() to program interrupt controller when start/stop interrupts.

2014-11-23ARM: dts: imx6qdl: Enable CODA960 VPUPhilipp Zabel
This patch adds links to the on-chip SRAM and reset controller nodes and switches the interrupts. Make the BIT processor interrupt, which exists on all variants, the first one. The JPEG unit interrupt, which does not exist on i.MX27 and i.MX5 thus is an optional second interrupt. Use different compatible strings for i.MX6Q/D and i.MX6S/DL, as they have to load separate firmware images for some reason.

imx6q-tbs2910 board uses sgtl5000 codec and the machine file (imx-sgtl5000) already sets SSI in slave mode and codec in master mode, so there is no need for having this property.

2014-11-23ARM: dts: vf610: enable USB misc/phy nodes where necessaryStefan Agner
Since restructuring of the device tree files, the USB misc/phy nodes are disabled by default. Hence we need to enable those explicitly when USB is used. Signed-off-by: Stefan Agner <stefan@agner.ch> Signed-off-by: Shawn Guo <shawn.guo@linaro.org>

2014-11-23ARM: dts: pbab01: move i2c pins and frequency configuration into pfla02Dmitry Lavnikevich
Since pins and frequency are specific to module (pfla02), not base board (pbab02), it is better to be initialized in corresponding dts file. This patch fixes i2c2, i2c3 pin configuration which caused messages: imx6q-pinctrl 20e0000.iomuxc: no groups defined in /soc/aips-bus@02000000/iomuxc@020e0000/i2c2grp imx6q-pinctrl 20e0000.iomuxc: no groups defined in /soc/aips-bus@02000000/iomuxc@020e0000/i2c3grp imx6q-pinctrl 20e0000.iomuxc: unable to find group for node i2c2grp imx6q-pinctrl 20e0000.iomuxc: unable to find group for node i2c3grp Signed-off-by: Dmitry Lavnikevich <d.lavnikevich@sam-solutions.com> Signed-off-by: Shawn Guo <shawn.guo@linaro.org>

Add Colibri VF50 device tree files vf500-colibri.dtsi and vf500-colibri-eval-v3.dts, in line with the Colibri VF61 device tree files. However, to minimize dupplication we also add vf-colibri.dtsi and vf-colibri-eval-v3.dtsi which contain the common device tree nodes.

2014-11-23ARM: dts: vf610: create generic base device treesStefan Agner
This adds more generic base device trees for Vybrid SoCs. There are three series of Vybrid SoC commonly available: - VF3xx series: single core, Cortex-A5 without external memory - VF5xx series: single core, Cortex-A5 - VF6xx series: dual core, Cortex-A5/Cortex-M4 The second digit represents the presents of a L2 cache (VFx1x). The VF3xx series are not suitable for Linux especially since the internal memory is quite small (1.5MiB). The VF500 is essentially the base SoC, with only one core and without L1 cache. The VF610 is a superset of the VF500, hence vf500.dtsi is then included and enhanced by vf610.dtsi. There is no board using VF510 or VF600 currently, but, if needed, they can be added easily. The Linux kernel can also run on the Cortex-M4 CPU of Vybrid using !MMU support. This patchset creates a device tree structure which allows to share peripherals nodes for a VF6xx Cortex-M4 device tree too. The two CPU types have different views of the system: Foremost they are using different interrupt controllers, but also the memory map is slightly different. The base device tree vfxxx.dtsi allows to create SoC and board level device trees supporting the Cortex-M4 while reusing the shared peripherals nodes.

2014-11-23ARM: dts: vf610: assign oscillator to clock moduleStefan Agner
The clock controller module (CCM) has several clock inputs, which are connected to external crystal oscillators. To reflect this, assign these fixed clocks to the CCM node directly. This especially resolves initialization order dependencies we had with the earlier initialization code: When resolving of the fixed clocks failed in clk-vf610, the code created fixed clocks with a rate of 0.
