Can be tested with OpenSBI v1.5. The patch require the following i2c patch: https://lore.kernel.org/all/IA1PR20MB4953DB82FB7D75BF8409FFF4BBB72@IA1PR20MB4953.namprd20.prod.outlook.com/ Changed from v8: 1. rename critical_action to repower_action, and add some comment 2. remove unnecessary wrap function 3. use guard macro to simplify mutex process. Changed from v7: 1. add mutex protected and fix the return value when writing "critical_action" Changed from v6: 1. restore the driver name to sg2042-mcu 2. remove unnecessary wrap function and check in the driver. 3. add dts and config entry. Changed from v5: 1. rename driver name to sgmcu as it will support more sophgo chip. 2. move some attr to debugfs. 3. add standard crit_hyst support 4. add documentation Changed from v4: 1. use fix patch for binding ref. 2. use unevaluatedProperties instead of additionalProperties for binding Changed from v3: 1. add thermal-sensor check. 2. change node type from syscon to hwmon Changed from v2: 1. fix bindings id path. Changed from v1: 1. Move patch from soc to hwmon. 2. Fix typo.
