Subject: [PATCH v3 0/3] usb: typec: hd3ss3220: enhance driver with port
 type, power opmode, and role preference settings

The TI HD3SS3220 Type-C controller supports configuring the port type,
the advertised power operation mode, and its role preference
through its I2C register map.

This patch series adds support for configuring these registers
based on existing fwnode properties and typec_operations.

Changes in v3:
- Drop PATCH 2/4 from v2 (using typec_get_fw_cap() for capability
  parsing)
- Implement parsing manually to have better control over
  each property being present / absent.
- If the "power-role"/"try-power-role" property is absent, we don't
  set the corresponding register during probe anymore, but let the
  chip use its default.
- Link to v2: https://lore.kernel.org/r/20241114-usb-typec-controller-enhancements-v2-0-362376856aea@zuehlke.com

Changes in v2:
- Better support optional fwnode properties being absent by setting
  defaults in struct typec_capability and checking return code of
  typec_get_fw_cap()
- Link to v1: https://lore.kernel.org/r/20241107-usb-typec-controller-enhancements-v1-0-3886c1acced2@zuehlke.com
