2024-02-02wifi: iwlwifi: simplify getting DSM from ACPIMiri Korenblit
As DSMs are going to be read from UEFI too, we need a unified API to get DSMs for both ACPI and UEFI. The difference in getting DSM in each one of these methods (ACPI, UEFI) is in the GUID, revision (0 for ACPI, 4 for UEFI), and size of the DSM values (8 or 32 for ACPI, 32 for UEFI). Therefore, change the iwl_acpi_get_dsm_x() to iwl_acpi_get_dsm() which determines the GUID, revision (these two are the same for all WiFi DSMs), and size (based on a func-to-size mapping) internally. While at it, fix DSM_FUNC_RFI_CONFIG to expect a 32-bit value (as defined in Intel BIOS spec) and not a 8-bit one.

2021-08-26iwlwifi: support reading and storing EWRD revisions 1 and 2Luca Coelho
As an extension to the WRDS support for revisions 1 and 2, do the same for the EWRD tables. These tables have a very similar format to the WRDS table, so most of the code is similar.

2021-08-26iwlwifi: acpi: support reading and storing WRDS revision 1 and 2Luca Coelho
Change the SAR profile tables storage to revision 2 regardless of the revision we read from ACPI. Revision 2 is a superset of revision 1, which is in turn a superset of revision 0, so they can all be stored inside revision 2. Add support for reading and storing also revisions 1 and 2, whose only difference is the number of chains and number of sub-bands. So most of the code revolves around passing different chain and sub-band sizes. With this patch we still pass only revision 0 to the firmware, but that will be changed in a separate patch.

2021-08-26iwlwifi: remove ACPI_SAR_NUM_TABLES definitionLuca Coelho
This definition was only used to pass the size of the tables in the FW API to the iwl_sar_select_profile() function, but we should actually pass the definition from the FW API file. We don't have the concept of tables in the ACPI definition, so we can remove it.

2021-08-26iwlwifi: convert flat SAR profile table to a struct versionLuca Coelho
The SAR profiles have been stored in single-dimension arrays and the access has been done via a single index. We will soon need to support different revisions of this table, which will make the flat array even harder to handle. To prepare for that, convert the single-dimension array to a struct with substructures.
