* MIPS: Netlogic: Fix 0x0x prefixes.Antonio Ospite2015-09-031-1/+1
| | | | | | | | | | | | Fix the 0x0x prefix in integer constants, in this case the registers interval is actually 0x8065 .. 0x80A4 as confirmed some lines above in the code.

* MIPS: Netlogic: Use chip_data for irq_chip methodsKamlakant Patel2015-09-031-6/+6
| | | | | | | | | | | | | Update mips/netlogic/common/irq.c and mips/pci/msi-xlp.c to use chip_data to store interrupt controller data pointer. It uses handler_data now, and that causes errors when an API (like the GPIO subsystem) tries to use the handler data.

* MIPS: netlogic: Prepare ipi handlers for irq argument removalThomas Gleixner2015-08-261-2/+4
| | | | | | | | | | | | | | | | | The irq argument of most interrupt flow handlers is unused or merily used instead of a local variable. The handlers which need the irq argument can retrieve the irq number from the irq descriptor. Search and update was done with coccinelle and the invaluable help of Julia Lawall.

* MIPS: SMP: Don't increment irq_count multiple times for call function IPIsAlex Smith2015-08-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | The majority of SMP platforms handle their IPIs through do_IRQ() which calls irq_{enter/exit}(). When a call function IPI is received, smp_call_function_interrupt() is called which also calls irq_{enter,exit}(), meaning irq_count is raised twice. When tick broadcasting is used (which is implemented via a call function IPI), this incorrectly causes all CPU idle time on the core receiving broadcast ticks to be accounted as time spent servicing IRQs, as account_process_tick() will account as such if irq_count is greater than 1. This results in 100% CPU usage being reported on a core which receives its ticks via broadcast. This patch removes the SMP smp_call_function_interrupt() wrapper which calls irq_{enter,exit}(). Platforms which handle their IPIs through do_IRQ() now call generic_smp_call_function_interrupt() directly to avoid incrementing irq_count a second time. Platforms which don't (loongson, sgi-ip27, sibyte) call generic_smp_call_function_interrupt() wrapped in irq_{enter,exit}().

* | mips: xlp: copy built-in DTB out of init sectionRob Herring2014-04-301-16/+1
|/ | | | | | | | | | | | | | The existing code is buggy because built-in DTBs are in init memory. It is also broken because the reserved bootmem was then freed after unflattening, but the unflattened tree points to data in the flat tree. Fix this by using the unflatten_and_copy_device_tree function. This removes all accesses to FDT header data by the arch code.

The patch series describes this core as follows. "The interAptiv is a power-efficient multi-core microprocessor for use in system-on-chip (SoC) applications. The interAptiv combines a multi-threading pipeline with a coherence manager to deliver improved computational throughput and power efficiency. The interAptiv can contain one to four MIPS32R3 interAptiv cores, system level coherence manager with L2 cache, optional coherent I/O port, and optional floating point unit." The platform specific patches touch all 3 Broadcom families. It adds support for the new Broadcom/Netlogix XLP9xx Soc, building a common BCM63XX SMP kernel for all BCM63XX SoCs regardless of core type/count and full gpio button/led descriptions for BCM47xx. The rest of the series are cleanups and bug fixes that are MIPS generic and consist largely of changes that Imgtec/MIPS had published in their linux-mti-3.10.git stable tree.
