From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Tomas Winkler Date: Mon, 5 Mar 2018 20:13:35 +0200 Subject: [PATCH] tpm: factor out tpm 1.x duration calculation to tpm1-cmd.c Factor out TPM 1.x commands calculation into tpm1-cmd.c file. and change the prefix from tpm_ to tpm1_. No functional change is done here. V2-V3: Rebase V4: 1. Remove the licence statement it's already covered by SPDX. 2. Add kdoc to tpm1_calc_ordinal_duration(). V5: Adjust the kdoc to the new standard.
