[PATCH 3/3] powerpc: Convert fsl_rstcr_restart to a reset handler
Andrey Smirnov
andrew.smirnov at gmail.com
Tue Jul 26 14:25:14 AEST 2016
Convert fsl_rstcr_restart into a function to be registered with
register_reset_handler() API and introduce fls_rstcr_restart_register()
function that can be added as an initcall that would do aforementioned
registration.
