dt-bindings: arm, gic-v3: require that reserved cells are always 0

2016-02-12T22:15:25Z

The arm,gic-v3 binding was written with good intentions and doesn't enforce interrupt-cells to be 3, therefore making it easy to extend the irq description in future if necessary: > Cells 4 and beyond are reserved for future use. Unfortunately, this sentence is immediately followed up with: > When the 1st cell has a value of 0 or 1, cells 4 and beyond act as > padding, and may be ignored. It is recommended that padding cells > have a value of 0. Consequently, any extensions to the PPI or SPI interrupt specifiers must be able to work with random crap from legacy DTs, effectively necessitating a new interrupt type in the first cell. Sigh. This patch fixes the text so that additional, reserved cells are required to be zero. This looks like a reasonable thing to require and is already satisifed by the .dts files in-tree.

Pull MIPS updates from Ralf Baechle: "This is the main pull request for MIPS for 4.5 plus some 4.4 fixes. The executive summary: - ATH79 platform improvments, use DT bindings for the ATH79 USB PHY. - Avoid useless rebuilds for zboot. - jz4780: Add NEMC, BCH and NAND device tree nodes - Initial support for the MicroChip's DT platform. As all the device drivers are missing this is still of limited use. - Some Loongson3 cleanups. - The unavoidable whitespace polishing. - Reduce clock skew when synchronizing the CPU cycle counters on CPU startup. - Add MIPS R6 fixes. - Lots of cleanups across arch/mips as fallout from KVM. - Lots of minor fixes and changes for IEEE 754-2008 support to the FPU emulator / fp-assist software. - Minor Ralink, BCM47xx and bcm963xx platform support improvments. - Support SMP on BCM63168" * 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus: (84 commits) MIPS: zboot: Add support for serial debug using the PROM MIPS: zboot: Avoid useless rebuilds MIPS: BMIPS: Enable ARCH_WANT_OPTIONAL_GPIOLIB MIPS: bcm63xx: nvram: Remove unused bcm63xx_nvram_get_psi_size() function MIPS: bcm963xx: Update bcm_tag field image_sequence MIPS: bcm963xx: Move extended flash address to bcm_tag header file MIPS: bcm963xx: Move Broadcom BCM963xx image tag data structure MIPS: bcm63xx: nvram: Use nvram structure definition from header file MIPS: bcm963xx: Add Broadcom BCM963xx board nvram data structure MAINTAINERS: Add KVM for MIPS entry MIPS: KVM: Add missing newline to kvm_err() MIPS: Move KVM specific opcodes into asm/inst.h MIPS: KVM: Use cacheops.h definitions MIPS: Break down cacheops.h definitions MIPS: Use EXCCODE_ constants with set_except_vector() MIPS: Update trap codes MIPS: Move Cause.ExcCode trap codes to mipsregs.h MIPS: KVM: Make kvm_mips_{init,exit}() static MIPS: KVM: Refactor added offsetof()s MIPS: KVM: Convert EXPORT_SYMBOL to _GPL ...

irqchip/ts4800: Add documentation for TS-4800 interrupt controller

2015-12-29T10:58:53Z

This is an interrupt-controller implemented in an FPGA, to multiplex interrupts generated from other IPs. The FPGA usually uses a GPIO as a parent interrupt controller to notify that one of the multiplexed interrupts has triggered.
