[v1] Add Axiado AX3000 eMMC Host Controller Support

[PATCH 5/8] dt-bindings: mmc: axiado: Add axiado eMMC variant

Posted by Tzu-Hao Wei 1 month, 2 weeks ago

From: SriNavmani A <srinavmani@axiado.com>

Add device tree binding variant for the Axiado AX3000 Arasan eMMC
controller. This variant identifies the specific eMMC controller
implementation used on the AX3000 SoC and enables the appropriate
driver configuration.
