    [PATCH] tpm: command duration update · 9e18ee19
    Kylene Jo Hall authored
    With the TPM 1.2 Specification, each command is classified as short, medium or
    long and the chip tells you the maximum amount of time for a response to each
    class of command.  This patch provides and array of the classifications and a
    function to determine how long the response should be waited for.  Also, it
    uses that information in the command processing to determine how long to poll
    for.  The function is exported so the 1.2 driver can use the functionality to
    determine how long to wait for a DataAvailable interrupt if interrupts are
    being used.
