Subject: [PATCH v1 0/3] Load cros_ec_ucsi from OF and ACPI definitions

The ChromeOS UCSI driver (cros_ec_ucsi) currently gets added as
subdevice of cros_ec_dev. But without it being defined by an ACPI
node or in the OF device tree, the typec connectors are not correctly
associated with other part of the device tree. This series updates the
cros_ec_ucsi driver to load based on device definitions in ACPI and OF.
It also changes the cros_ec_dev driver to block adding cros_ec_ucsi
as a subdevice if it is defined in the device tree.

  mfd: cros_ec: Don't add cros_ec_ucsi if it is defined in OF or ACPI
