Subject: [PATCH v12 1/2] platform/chrome: Update ChromeOS EC header for UCSI
Date: Tue, 31 Dec 2024 13:10:46 +0000 [thread overview]
Message-ID: <20241231131047.1757434-2-ukaszb@chromium.org> (raw)
In-Reply-To: <20241231131047.1757434-1-ukaszb@chromium.org>
From: Pavan Holla <pholla@chromium.org>
Add EC host commands for reading and writing UCSI structures
in the EC. The corresponding kernel driver is cros-ec-ucsi.
Also update PD events supported by the EC.
