From: Abhishek Pandit-Subedi <abhishekpandit@chromium.org> Hi Heikki, This series starts the work adding UCSI 3.0 support to the UCSI driver. There's a couple of pieces to start here: * Add version checks and limit read size on 1.2. * Update Connector Status and Connector Capability structures. * Expose Partner PD revision from Capability data. These were tested against on a 6.6 kernel running a usermode PPM against a Realtek Evaluation board. One additional note: there are a lot more unaligned fields in UCSI now and the struct definitions are getting a bit out of hand. We can discuss alternate mechanisms for defining these structs in the patch that changes these structures.
