- Make clock reset functions into HALs. This way we can control clock-reset logic for any chip. Set clock-reset HAL pointers to appropriate functions. - Remove clock-reset function wrappers as these will not be required and corresponding HAL pointers will be used. - As clock reset init is defined as a HAL, modify probe logic to initialize chip info before invoking any HALs. - Move common/primary HAL validation logic to common code and implement new HAL to validate chip specific HALs. This way we can ensure that HAL pointers are set as expected. - Keep only one definition for t234_hwpm_init_chip_info as t234 should always be initialized and hence only single definition should be available. - Expected return value of 0 indicates success and any other value (mostly negative in current logic) indicates error, compare function returns with 0 to print error in tegra_hwpm_release(). - Since a build can support both ACPI and device tree, update init_chip_info() to retrieve chip information from ACPI and device tree in case of failure.
