FROMGIT: scsi: ufs: core: Support Updating UIC Command Timeout
The default UIC command timeout still remains 500ms. Allow platform drivers to override the UIC command timeout if desired. In a real product, the 500ms timeout value is probably good enough. However, during the product development where there are a lot of logging and debug messages being printed to the uart console, interrupt starvations happen occasionally because the uart may print long debug messages from different modules in the system. While printing, the uart may have interrupts disabled for more than 500ms, causing UIC command timeout. The UIC command timeout would trigger more printing from the UFS driver, and eventually a watchdog timeout may occur unnecessarily. Add support for overriding the UIC command timeout value with the newly created uic_cmd_timeout kernel module parameter. Default value is 500ms. Supported values range from 500ms to 2 seconds.
