Subject: [PATCH] ARM: dts: nuvoton: Add MMC Nodes
Date: Fri,  4 Apr 2025 12:11:44 -0700	[thread overview]
Message-ID: <20250404191144.4111788-1-william@wkennington.com> (raw)

We have the driver support code, now we just need to expose the device
node which can export the SDHCI and SDMMC properties for the 2 MMC
controllers in the npcm7xx. Tested on real hardware to verify that the
MMC controller is functional with filesystem access.
