Subject: [PATCH v5 0/3] usb: typec: ucsi: Adding support for UCSI 3.0
Date: Fri,  9 Feb 2024 14:37:29 -0800	[thread overview]
Message-ID: <20240209223824.622869-1-abhishekpandit@chromium.org> (raw)


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 v5:
  - Change min_t to clamp

Changes in v4:
  - Added missing Tested-By tags from v1 and reviewed-by tags.
  - Fix BCD translation of PD Major Rev
  - Replace IS_MIN_VERSION macro and just compare version directly.

Changes in v3:
  - Change include to asm/unaligned.h and reorder include.

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