Subject: [PATCH v3 5/6] pinctrl: scmi: add blocklist
Date: Sun, 28 Apr 2024 13:07:51 +0800 [thread overview]
Message-ID: <20240428-pinctrl-scmi-oem-v3-v3-5-eda341eb47ed@nxp.com> (raw)
In-Reply-To: <20240428-pinctrl-scmi-oem-v3-v3-0-eda341eb47ed@nxp.com>
From: Peng Fan <peng.fan@nxp.com>
i.MX95 will have its own pinctrl scmi driver, so need block
pinctrl-scmi driver for i.MX95, otherwise there will be two pinctrl
devices for a single scmi protocol@19.
