And introduce the new architecture LVTS (low pressure 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 mt6873 and mt8192. Change in v5: - Use 'git mv' for the relocated file. Change in v4: - Rebase to kernel-v5.13-rc1 - Resend Change in v3: - [2/3] - change the expression in the lvts_temp_to_raw to dev_s64. Change in v2: - Rebase to kernel-5.11-rc1. - [2/3] - 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 invalid number in the lvts_init.
