From: Balsam CHIHI <bchihi@baylibre.com> This series moves thermal files related to MediaTek to the mediatek folder. And introduce the new architecture LVTS (low voltage thermal sensor) driver to report the highest temperature in the SoC and record the highest temperature sensor, each sensor as a hot zone. The LVTS body is divided into two parts, the LVTS controller and the LVTS device. The LVTS controller can connect up to 4 LVTS devices, and each LVTS device can connect up to 7 TSMCUs. The architecture will be the first to be used on mt8192 and mt8195. Changelog: Changes in v8.1 : - Fix Coding style issues - Rebase on top of next-20220803 - Add multi-instance support : - Rewrite DT-binding and DTS : - Add DT-binding and DTS for LVTS_v4 (MT8192 and MT8195) - One LVTS node for each HW Domain (AP and MCU) - One SW Instance for each HW Domain - Add a Kconfig sub-menu entry for LVTS and LVTS_v4 SoCs - Replace platform_get_resource by platform_get_mem_or_io to get Base Address - Replace platform_get_resource by platform_get_irq to get Interrupt Number - Add "lvts_" prefix to functions and structs Changes in v7 : - Fix coding style issues - Rewrite dt bindings - was not accurate - Use mt8195 for example (instead of mt8192) - Rename mt6873 to mt8192 - Remove clock name - Rebased on top of to series: - https://patchwork.kernel.org/project/linux-mediatek/list/?series=637849 - https://patchwork.kernel.org/project/linux-pm/list/?series=639386 Changes in v6 : - Remove temperature aggregation (it will be added in another series) - Update the way to read the temperature (read one sensor instead of all) - Add support of mt8195 Changes in v5 : - Use 'git mv' for the relocated file. Changes in v4 : - Rebase to kernel-v5.13-rc1 - Resend Changes in v3 : - change the expression in the lvts_temp_to_raw to dev_s64. Changes in v2 : - Rebase to kernel-5.11-rc1. - sort headers - remove initial value 0 of msr_raw in the lvts_temp_to_raw. - disconstruct the api of lvts_read_tc_msr_raw. - add the initial value max_temp = 0 and compare e.q. in the lvts_read_all_tc_temperature. - add the return with an invalid number in the lvts_init.
