Commit Message

Jonathan Cameron Jan. 29, 2023, 3:56 p.m. UTC
From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

The main blocker of this driver moving previously was non standard
ABI for the 180 degree offset channel. Now support for that channel
has been dropped, this simple driver can move out of staging.
