This series adds a driver for the Cr50 security chip and enables it on coral. This supports the 'tpm' command.
In order to make this work a few other changes are included: - Additional UCLASS_IRQ operations to support requesting and reading interrupts, using the device tree - A driver for ACPI general-purpose events
There are also a few small clean-ups to the recently landed Apollo Lake support.
This series relies on this patch:

Changes in v2: - Add new patch to allow iterating devices without uclass_get() - Add new patch to find a device by drvdata - Add new patch to change syscon to use helper function - Add new patch to change tegra driver to use helper function - Move intel-clock.h inclusion to the correct patch - Move 'success' comment into this patch - Update to use the new DM helper function - Move 'success' comment into previous patch - Move intel-clock.h inclusion to the correct patch - Significant rewrite of cr50 init procedure - Support use of interrupts - Update the commit message - Add new patches to handle requesting interrupts and interrupt state
