2019-01-24cr50: Add probe command to poll Cr50 until DID VID is validKeith Short
Added new routine cr50_i2c_probe() which ensures that communication with the Cr50 over I2C is good prior to attempting other initialization of the Cr50 and TPM state.

As the slave address of this chip is hardware configurable the function pca9538_get_dev() is used to get the right slave address.

2018-01-30drivers/i2c/tpm: Add irq_gpio support to tpm.Justin TerAvest
Grunt (a amd-stoneyridge based platform) uses a GPIO to interface with the tpm. This change allows devicetree entries to use a irq_gpio entry to describe the interface with the TPM.

2018-01-25drivers/i2c/designware: reduce API complication for bus configAaron Durbin
Right now dw_i2c_get_soc_cfg() is expecting the SoC to implement that callback for obtaining the bus config. However, we're currently forcing another parameter of struct device so one can do the lookup. This works for Intel-based systems since the struct device was needed to program the BAR, etc. However, from an API standpoint, it just complicates matters by needing to obtain the struct device. The SoC already has knowlege of its own devices so it can get the config itself by bus number. Therefore, remove that contraint from the API.

2018-01-24device/i2c_bus: allow i2c_bus and i2c_simple to coexistAaron Durbin
If one wants to implement both i2c_bus.h and i2c_simple.h APIs the compilation unit needs to be guarded or coordinated carefully with different compilation units. Instead, name the i2c_bus functions with _dev such that it indicates that they operate on struct device. One other change to allow i2c_bus.h to be built in non-ramstage environments is to ensure DEVTREE_CONST is used for the dev field in struct bus.
