* AVR32-clock: Combine nine seq_printf() calls into one call in clk_show()Markus Elfring2016-12-121-9/+19
| | | | | | | Some data were printed into a sequence by nine separate function calls. Print the same data by a single function call instead. Signed-off-by: Markus Elfring <elfring@users.sourceforge.net>
* AVR32-clock: Use seq_putc() in two functionsMarkus Elfring2016-12-121-3/+2
| | | | | | | | | A single character (line break) should be put into two sequences. Thus use the corresponding function "seq_putc". This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring <elfring@users.sourceforge.net>
* avr32: handle NULL as a valid clock objectAndy Shevchenko2015-07-271-1/+19
| | | | | | | | | Since NULL is used as valid clock object on optional clocks we have to handle this case in avr32 implementation as well. Fixes: e1824dfe0d8e (net: macb: Adjust tx_clk when link speed changes) Signed-off-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Acked-by: Hans-Christian Egtvedt <egtvedt@samfundet.no>
* avr32: add export.h to arch/avr32 for EXPORT_SYMBOL/THIS_MODULEPaul Gortmaker2011-10-311-0/+1
| | | | | | | Add it in where the module.h implicit presence was doing the job before. Signed-off-by: Paul Gortmaker <paul.gortmaker@windriver.com>
* avr32: fix deadlock when reading clock list in debugfsOle Henrik Jahren2011-04-131-8/+16
| | | | | | | | | | | When writing out /sys/kernel/debug/at32ap_clk, clock list lock is being held while clk_get() is called. clk_get() attempts to take the same lock, which results in deadlock. Introduce and call lock free version, __clk_get(), instead.

* avr32: Replace static clock list with dynamic linked listAlex Raimondi2008-10-051-12/+40
| | | | | | | | This replaces the at32_clock_list array with a linked list. Clocks can now be registered (added) to the list. Signed-off-by: Alex Raimondi <raimondi@miromico.ch> Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com>
* avr32: Add MMIO address definitions for certain controllersHaavard Skinnemoen2008-08-081-0/+2
| | | | | | | | Hardcoded MMIO base addresses are used a few places throughout the platform code. Move these into the chip-specific header file so that adding support for new chips becomes a bit easier. Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com>
* [AVR32] /sys/kernel/debug/at32ap_clkDavid Brownell2007-10-111-0/+116
| | | | | | | | | When debugfs is available, /sys/kernel/debug/at32ap_clk will provide a dump of the power manager registers and of the current clock tree. This can help sorting out various surprises, and when making runtime PM work. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>

| * [ARM] 4124/1: Rename mach-at91rm9200 and arch-at91rm9200 directoriesAndrew Victor2007-02-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that Linux includes support for the Atmel AT91SAM9260 and AT91SAM9261 processors in addition to the original Atmel AT91RM9200 (with support for more AT91 processors pending), the "mach-at91rm9200" and "arch-at91rm9200" directories should be renamed to indicate their more generic nature. The following git commands should be run BEFORE applying this patch: git-mv arch/arm/mach-at91rm9200 arch/arm/mach-at91 git-mv include/asm-arm/arch-at91rm9200 include/asm-arm/arch-at91 Signed-off-by: Andrew Victor <andrew@sanpeople.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

* [PATCH] avr32 architectureHaavard Skinnemoen2006-09-261-0/+148
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.
