W1_NEXT_PULLUP(9)                 W1 API internal to the kernel                 W1_NEXT_PULLUP(9)



NAME
       w1_next_pullup - register for a strong pullup

SYNOPSIS
       void w1_next_pullup(struct w1_master * dev, int delay);

ARGUMENTS
       dev
           the master device

       delay
           time in milliseconds

DESCRIPTION
       Put out a strong pull-up of the specified duration after the next write operation. Not all
       hardware supports strong pullups. Hardware that doesn't support strong pullups will sleep
       for the given time after the write operation without a strong pullup. This is a one shot
       request for the next write, specifying zero will clear a previous request. The w1 master
       lock must be held.

RETURN
       0=success, anything else=error
