2017-08-18include/device: Split i2c.h into threeNico Huber
Split `i2c.h` into three pieces to ease reuse of the generic defi- nitions. No code is changed. * `i2c.h` - keeps the generic definitions * `i2c_simple.h` - holds the current, limited to one controller driver per board, devicetree independent I2C interface * `i2c_bus.h` - will become the devicetree compatible interface for native I2C (e.g. non-SMBus) controllers Change-Id: I382d45c70f9314588663e1284f264f877469c74d Signed-off-by: Nico Huber <nico.huber@secunet.com> Reviewed-on: https://review.coreboot.org/20845 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Aaron Durbin <adurbin@chromium.org>
2016-09-06drivers/i2c/tpm: Add support for generating ACPI tableDuncan Laurie
Add code to generate an ACPI descriptor for an I2C TPM based on the device as described in devicetree.cb. This currently requires the devicetree to provide the HID, since we don't currently talk to the TPM in ramstage and I didn't want to add yet another init path for it here. This was tested on a reef board to ensure that the device is described properly in the SSDT.
