Hi Linus, This now my "official" first PR for v5.12. There's still some known issues in the tpm_tis driver *not& fixed in this first pull request, which trigger a warning but do not overally collapse the kernel by any means. The fixes are in good progress, but unfortunately there's still some fine tuning required before I can include to a pull request. I'm sure we will get them done around rc2/rc3. Better to make sure that the fixes do right things right, rather than rush them to a PR. That's also the reason why this comes so late. Sorry about that. I have also kind of "reorg" going on with my maintainer workflows, given the increased review activity in keyrings and SGX, which temporarily causes a bit overhead until becoming "status quo". New features ============ 1. Cr50 I2C TPM driver. 2. Sysfs exports of PCR registers in TPM 2.0 chips. Bug fixes ========= * This contains bug fixes for tpm_tis driver, which had a racy wait for hardware state change to be ready to send a command to the TPM chip. The bug has existed already since 2006, but has only made itself known in recent past. This is the same as the "last time" :-) * Otherwise there's bunch of fixes for not as alarming regressions. I think the list is about the same as last time, except I added fixes for some disjoint bugs in trusted keys that I found some time ago. /Jarkko The following changes since commit f40ddce88593482919761f74910f42f4b84c004b: Linux 5.11 (2021-02-14 14:32:24 -0800) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/jarkko/linux-tpmdd.git/ tags/tpmdd-next-v5.12-rc1-v2 for you to fetch changes up to 8c657a0590de585b1115847c17b34a58025f2f4b: KEYS: trusted: Reserve TPM for seal and unseal operations (2021-02-16 10:40:28 +0200) ---------------------------------------------------------------- tpmdd updates for Linux v5.12-rc1 ---------------------------------------------------------------- Andrew Zaborowski (1): keys: Update comment for restrict_link_by_key_or_keyring_chain Duncan Laurie (1): char: tpm: add i2c driver for cr50 Gustavo A.
