-* H1 Secure Microcontroller with Cr50 Firmware on SPI Bus.
-
-H1 Secure Microcontroller running Cr50 firmware provides several
-functions, including TPM-like functionality. It communicates over
-SPI using the FIFO protocol described in the PTP Spec, section 6.
-
-Required properties:
-- compatible: Should be "google,cr50".
-- spi-max-frequency: Maximum SPI frequency.
-
-Example:
-
-&spi0 {
- tpm@0 {
- compatible = "google,cr50";
- reg = <0>;
- spi-max-frequency = <800000>;
- };

-Trusted Computing Group MMIO Trusted Platform Module
-
-The TCG defines multi vendor standard for accessing a TPM chip, this
-is the standard protocol defined to access the TPM via MMIO. Typically
-this interface will be implemented over Intel's LPC bus.
-
-Refer to the 'TCG PC Client Specific TPM Interface Specification (TIS)' TCG
-publication for the specification.
-
-Required properties:
-
-- compatible: should contain a string below for the chip, followed by
- "tcg,tpm-tis-mmio". Valid chip strings are:
- * "atmel,at97sc3204"
-- reg: The location of the MMIO registers, should be at least 0x5000 bytes
-- interrupts: An optional interrupt indicating command completion.
-
-Example:
-
- tpm_tis@90000 {
- compatible = "atmel,at97sc3204", "tcg,tpm-tis-mmio";
- reg = <0x90000 0x5000>;
