2022-08-03mfd: remove reference to AVR32 architecture in atmel-smc.cHans-Christian Noren Egtvedt1-2/+2
The AVR32 architecture does no longer exist in the Linux kernel, hence remove a reference to it in comments to avoid confusion. Signed-off-by: Hans-Christian Noren Egtvedt <egtvedt@samfundet.no>
2020-07-06mfd: atmel-smc: Add missing colon(s) for 'conf' argumentsLee Jones1-2/+2
Kerneldoc valication gets confused if syntax isn't "@.*: ". Adding the missing colons squashes the following W=1 warnings: drivers/mfd/atmel-smc.c:247: warning: Function parameter or member 'conf' not described in 'atmel_smc_cs_conf_apply' drivers/mfd/atmel-smc.c:268: warning: Function parameter or member 'conf' not described in 'atmel_hsmc_cs_conf_apply' Cc: Nicolas Ferre <nicolas.ferre@microchip.com> Cc: Alexandre Belloni <alexandre.belloni@bootlin.com> Cc: Ludovic Desroches <ludovic.desroches@microchip.com> Cc: Boris Brezillon <boris.brezillon@free-electrons.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>

2018-05-29mfd: syscon: atmel-smc: Include string.hSebastian Andrzej Siewior1-0/+1
The string.h header file is needed for the memset() definition. The RT build fails because it is not pulled in via other header files.

2017-09-05mfd: syscon: atmel-smc: Add helper to retrieve register layoutLudovic Desroches1-14/+53
For HSMC controller, the register layout depends on the device i.e. the offset of setup, pulse, cycle, mode and timings registers is not the same. An helper is added to provide the correct register layout.

2017-07-26memory: atmel-ebi: Fix smc cycle xlate converterAlexander Dahl1-1/+1
The converter function for translating ns timings in register values was initialized with a wrong function pointer. This resulted in wrong register values also for the setup and pulse registers when configuring the EBI interface trough dts. Includes a small fix in a comment of the smc driver, which was probably just a copy'n'paste mistake.

2017-04-27mfd: syscon: atmel-smc: Add new helpers to ease SMC regs manipulationBoris Brezillon1-0/+314
These new helpers + macro definitions are meant to replace the old ones which are unpractical to use. Note that the macros and function prefixes have been intentionally changed to ATMEL_[H]SMC_XX and atmel_[h]smc_ to reflect the fact that this IP is also embedded in avr32 SoCs (and not only in at91 ones).
