W1_RESET_RESUME_COMM(9)           W1 API internal to the kernel           W1_RESET_RESUME_COMM(9)



NAME
       w1_reset_resume_command - resume instead of another match ROM

SYNOPSIS
       int w1_reset_resume_command(struct w1_master * dev);

ARGUMENTS
       dev
           the master device

DESCRIPTION
       When the workflow with a slave amongst many requires several successive commands a reset
       between each, this function is similar to doing a reset then a match ROM for the last
       matched ROM. The advantage being that the matched ROM step is skipped in favor of the
       resume command. The slave must support the command of course.

       If the bus has only one slave, traditionnaly the match ROM is skipped and a “SKIP ROM” is
       done for efficiency. On multi-slave busses, this doesn't work of course, but the resume
       command is the next best thing.

       The w1 master lock must be held.
