2019-05-30treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 194Thomas Gleixner1-1/+1
Based on 1 normalized pattern(s): license terms gnu general public license gpl version 2 extracted by the scancode license scanner the SPDX license identifier GPL-2.0-only has been chosen to replace the boilerplate/reference in 161 file(s).

2018-05-16mfd: abx500-core: Improve two size determinations in abx500_register_ops()Markus Elfring1-4/+2
Replace the specification of two data structures by pointer dereferences as the parameter for the operator "sizeof" to make the corresponding size determination a bit safer according to the Linux coding style convention. This issue was detected by using the Coccinelle software.

2016-11-29mfd: abx500-core: drop unused MODULE_ tags from non-modular codePaul Gortmaker1-5/+2
The Kconfig currently controlling compilation of this code is: drivers/mfd/Kconfig:config ABX500_CORE drivers/mfd/Kconfig: bool "ST-Ericsson ABX500 Mixed Signal Circuit register functions" ...meaning that it currently is not being built as a module by anyone. Lets remove the couple traces of modular infrastructure use, so that when reading the driver there is no doubt it is builtin-only. We delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments. We replace module.h with init.h and export.h ; the latter since the file does export some symbols.

2014-06-03mfd: abx500-core: Remove unused function abx500_dump_all_banks()Lee Jones1-20/+0
abx500_dump_all_banks() has no callers in the kernel, so it's probably safe to remove it. Cc: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Lee Jones <lee.jones@linaro.org>

On systems with CONFIG_FRAME_WARN=1024, compiler warns the allocation of an object of struct device on stack. Make the allocation dynamically to fix the warning.

2013-02-04mfd: abx500-core: Provide an API to dump all ABx500 registersMian Yousaf Kaukab1-0/+16
Some drivers can detect subsystem failures e.g. shared memory driver can detect modem sub system failures. It would be helpful in analyzing these failures if AB register dump is available at that point. This patch adds the API for the drivers to dump AB registers in the kernel log.

2010-05-28mfd: AB3100 register access change to abx500 APIMattias Wallin1-0/+157
The interface for the AB3100 is changed to make way for the ABX500 family of chips: AB3550, AB5500 and future ST-Ericsson Analog Baseband chips. The register access functions are moved out to a separate struct abx500_ops. In this way the interface is moved from the implementation and the sub functionality drivers can keep their interface intact when chip infrastructure and communication mechanisms changes. We also define the AB3550 device IDs and the AB3550 platform data struct and convert the catenated 32bit event to an array of 3 x 8bits.
