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.
