2024-07-01ACPI: PMIC: Constify struct pmic_tableChristophe JAILLET1-2/+2
'struct pmic_table' is not modified in these drivers. Constifying this structure moves some data to a read-only section, so increase overall security. On a x86_64, with allmodconfig, as an example: Before: ====== text data bss dec hex filename 3811 786 0 4597 11f5 drivers/acpi/pmic/intel_pmic_xpower.o text data bss dec hex filename 4147 450 0 4597 11f5 drivers/acpi/pmic/intel_pmic_xpower.o Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Link: https://patch.msgid.link/a6c9b1bcdf259adabbcaf91183d3f5ab87a98600.1719644292.git.christophe.jaillet@wanadoo.fr Reviewed-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Rafael J.

2021-12-08ACPI: PMIC: allow drivers to provide a custom lpat_raw_to_temp() functionHans de Goede1-0/+1
The LPAT tables used in the DSDT for some PMICs require special handling, allow the PMIC OpRegion drivers to provide an alternative implementation by adding a lpat_raw_to_temp function pointer to struct pmic_table; and initialize this to the default acpi_lpat_raw_to_temp function for all PMICs.

2018-01-11ACPI / PMIC: Convert to use builtin_platform_driver() macroAndy Shevchenko1-6/+1
All of PMIC OpRegion drivers can't be modules, thus, convert them to use builtin_platform_driver() macro and remove redundant MODULE_*() macros. No functional change intended.

2017-12-13ACPI / PMIC: constify platform_device_idArvind Yadav1-1/+1
platform_device_id are not supposed to change at runtime. All functions working with platform_device_id provided by <linux/platform_device.h> work with const platform_device_id. So mark the non-const structs as const. Signed-off-by: Arvind Yadav <arvind.yadav.cs@gmail.com> Acked-by: Mika Westerberg <mika.westerberg@linux.intel.com> Signed-off-by: Rafael J.

2016-07-16ACPI / PMIC: remove modular references from non-modular codePaul Gortmaker1-5/+1
The Kconfig currently controlling compilation of these files are: drivers/acpi/Kconfig:menuconfig PMIC_OPREGION drivers/acpi/Kconfig: bool "PMIC (Power Management Integrated Circuit) operation region support" drivers/acpi/Kconfig:config BXT_WC_PMIC_OPREGION drivers/acpi/Kconfig: bool "ACPI operation region support for BXT WhiskeyCove PMIC" drivers/acpi/Kconfig:config XPOWER_PMIC_OPREGION drivers/acpi/Kconfig: bool "ACPI operation region support for XPower AXP288 PMIC" ...meaning they currently are not being built as a module by anyone. Lets remove the couple traces of modular infrastructure use, so that when reading the code 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. One file was using module_init. Since module_init translates to device_initcall in the non-modular case, the init ordering remains unchanged with this commit. In one case we replace the module.h with export.h since that file is exporting some symbols, but does not use __init. The other two are using __init and so module.h gets replaced with init.h there.
