* avr32: replace simple_strtoul() with kstrtoul()Ramkumar Ramachandra2014-04-011-22/+26
| | | | | | | | | | | simple_strtoul() is marked for obsoletion; use the newer and more pleasant kstrtoul() in its place.

* cpu: convert 'cpu' and 'machinecheck' sysdev_class to a regular subsystemKay Sievers2011-12-211-37/+37
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This moves the 'cpu sysdev_class' over to a regular 'cpu' subsystem and converts the devices to regular devices. The sysdev drivers are implemented as subsystem interfaces now. After all sysdev classes are ported to regular driver core entities, the sysdev implementation will be entirely removed from the kernel. Userspace relies on events and generic sysfs subsystem infrastructure from sysdev devices, which are made available with this conversion.

* sysdev: Pass the attribute to the low level sysdev show/store functionAndi Kleen2008-07-221-13/+25
| | | | | | | | | | | | | | | | | | | | | | This allow to dynamically generate attributes and share show/store functions between attributes. Right now most attributes are generated by special macros and lots of duplicated code. With the attribute passed it's instead possible to attach some data to the attribute and then use that in shared low level functions to do different things. I need this for the dynamically generated bank attributes in the x86 machine check code, but it'll allow some further cleanups. I converted all users in tree to the new show/store prototype. It's a single huge patch to avoid unbisectable sections. Runtime tested: x86-32, x86-64 Compiled only: ia64, powerpc Not compile tested/only grep converted: sh, arm, avr32 Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* [AVR32] Provide more CPU information in /proc/cpuinfo and dmesgHaavard Skinnemoen2008-01-251-26/+68
| | | | | | | | | | | | | | | | | Add the following fields to /proc/cpuinfo: * chip type and revision (from the JTAG chip id) * cpu MHz (from clk_get_rate()) * features (from the CONFIG0 register) Also rename "cpu family" to "cpu arch" and "cpu type" to "cpu core" to remove some ambiguity. Show chip type and revision at bootup, and clarify that the other kinds of IDs that we're already printing are for the cpu core and architecture. Rename "AP7000" to "AP7" since that's the name of the core. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
* [AVR32] Clean up cpu identification and add features bitmapHaavard Skinnemoen2007-04-271-20/+44
| | | | | | | | | Clean up the cpu identification code, using definitions from <asm/sysreg.h> instead of hardcoded constants. Also, add a features bitmap to struct avr32_cpuinfo to allow other code to make decisions based upon what the running cpu is actually capable of.

* [PATCH] avr32 architectureHaavard Skinnemoen2006-09-261-0/+327
This adds support for the Atmel AVR32 architecture as well as the AT32AP7000 CPU and the AT32STK1000 development board. AVR32 is a new high-performance 32-bit RISC microprocessor core, designed for cost-sensitive embedded applications, with particular emphasis on low power consumption and high code density. The AVR32 architecture is not binary compatible with earlier 8-bit AVR architectures. The AVR32 architecture, including the instruction set, is described by the AVR32 Architecture Manual, available from http://www.atmel.com/dyn/resources/prod_documents/doc32000.pdf The Atmel AT32AP7000 is the first CPU implementing the AVR32 architecture. It features a 7-stage pipeline, 16KB instruction and data caches and a full Memory Management Unit. It also comes with a large set of integrated peripherals, many of which are shared with the AT91 ARM-based controllers from Atmel. Full data sheet is available from http://www.atmel.com/dyn/resources/prod_documents/doc32003.pdf while the CPU core implementation including caches and MMU is documented by the AVR32 AP Technical Reference, available from http://www.atmel.com/dyn/resources/prod_documents/doc32001.pdf Information about the AT32STK1000 development board can be found at http://www.atmel.com/dyn/products/tools_card.asp?tool_id=3918 including a BSP CD image with an earlier version of this patch, development tools (binaries and source/patches) and a root filesystem image suitable for booting from SD card. Alternatively, there's a preliminary "getting started" guide available at http://avr32linux.org/twiki/bin/view/Main/GettingStarted which provides links to the sources and patches you will need in order to set up a cross-compiling environment for avr32-linux. This patch, as well as the other patches included with the BSP and the toolchain patches, is actively supported by Atmel Corporation.
