Subject: [PATCH v2 0/3] usb: typec: ucsi: Adding support for UCSI 3.0
Date: Wed, 24 Jan 2024 16:44:51 -0800	[thread overview]
Message-ID: <20240125004456.575891-1-abhishekpandit@google.com> (raw)

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.

Thanks,
Abhishek

Changes in v2:
  - Changed log message to DEBUG
  - Formatting changes and update macro to use brackets.
  - Fix incorrect guard condition when checking connector capability.
