Subject: [PATCH v1 08/11] i2c: designware-pci: Add a note about struct dw_scl_sda_cfg usage
Date: Tue, 7 Dec 2021 21:21:56 +0200 [thread overview]
Message-ID: <20211207192159.41383-8-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20211207192159.41383-1-andriy.shevchenko@linux.intel.com>
Add a note about struct dw_scl_sda_cfg usage to discourage people
of using this structure on new platforms. Instead they should try
hard to put the needed information into firmware descriptions.
