Subject: [PATCH v2 1/2] dt-bindings: mmc: mtk-sd: Document support for Airoha AN7581 SoC
Date: Tue, 27 Oct 2026 15:40:00 +0100 [thread overview]
Message-ID: <20261027144002.10606-1-ansuelsmth@gmail.com> (raw)
Add dedicated compatible for Airoha AN7581 SoC integrated MMC controller.
The MMC controller is based on the MT7988 with the difference that it does
have a single clock controlling it.
Add the dedicated compatible to describe the 2 register requirement and
permit to define only 2 clock (the main one and a fixed clock for HS)
Signed-off-by: Christian Marangi <ansuelsmth@gmail.com>
---
Changes v2:
- Also add compatible to restrict clock-names for source and hclk
