dt-bindings: remove 'interrupt-parent' from bindings

2018-07-25T20:09:39+00:00

'interrupt-parent' is often documented as part of define bindings, but it is really outside the scope of a device binding. It's never required in a given node as it is often inherited from a parent node. Or it can be implicit if a parent node is an 'interrupt-controller' node. So remove it from all the binding files.

Merge branch 'next-tpm' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security

Pull TPM updates from James Morris: "Here are the TPM updates from Jarkko for v4.14, which I've placed in their own branch (next-tpm). I ended up cherry-picking them as other changes had been made in Jarkko's branch after he sent me his original pull request. I plan on maintaining a separate branch for TPM (and other security subsystems) from now on. From Jarkko: 'Not much this time except a few fixes'" * 'next-tpm' of git://git.kernel.org/pub/scm/linux/kernel/git/jmorris/linux-security: tpm: ibmvtpm: simplify crq initialization and document crq format tpm: replace msleep() with usleep_range() in TPM 1.2/2.0 generic drivers Documentation: tpm: add powered-while-suspended binding documentation tpm: tpm_crb: constify acpi_device_id. tpm: vtpm: constify vio_device_id

dt-bindings: Remove "status" from examples

2017-09-05T15:03:06+00:00

Pretty much any node can have a status property, so it doesn't need to be in examples. Converted with the following command and removed examples with SoC and board specific splits: git grep -l -E 'status.*=.*' Documentation/devicetree/ | xargs sed -i -E '/\sstatus.*=.*"(disabled|ok|okay)/d' Acked-by: Mark Rutland Signed-off-by: Rob Herring

tpm_tis: Allow tpm_tis to be bound using DT

2016-11-27T23:31:31+00:00

This provides an open firwmare driver binding for tpm_tis. OF is useful on arches where ACPI/PNP is not used. The tcg,tpm-tis-mmio register map interface is specified by the TCG. Reviewed-by: Rob Herring Signed-off-by: Jason Gunthorpe Reviewed-by: Jarkko Sakkinen Signed-off-by: Jarkko Sakkinen

Documentation: tpm: add the Physical TPM device tree binding documentation

2016-11-27T23:31:31+00:00

Newly added support of TPM 2.0 eventlog securityfs pseudo files in tpm device driver consumes device tree bindings representing I2C based Physical TPM. This patch adds the documentation for corresponding device tree bindings of I2C based Physical TPM. These bindings are similar to vtpm device tree bindings being used on IBM Power7+ and Power8 Systems running PowerVM.

Documentation: tpm: add the IBM Virtual TPM device tree binding documentation

2016-11-27T23:31:31+00:00

Virtual TPM, which is being used on IBM POWER7+ and POWER8 systems running POWERVM, is currently supported by tpm device driver but lacks the documentation. This patch adds the missing documentation for the existing support. Suggested-by: Jason Gunthorpe Signed-off-by: Nayna Jain Acked-by: Rob Herring Signed-off-by: Jarkko Sakkinen

tpm/tpm_tis_spi: Add support for spi phy

2016-06-25T14:28:57+00:00

Spi protocol standardized by the TCG is now supported by most of TPM vendors. It supports SPI Bit Protocol as describe in the TCG PTP specification (chapter 6.4.6 SPI Bit Protocol). Irq mode is not supported. This commit is based on the initial work by Peter Huewe.
