From 5e52cf6bf3c7216de1ee4a74ee002cb99b3f6c11 Mon Sep 17 00:00:00 2001 From: Matthias Schiffer Date: Thu, 27 Jul 2023 15:21:20 +0200 Subject: [PATCH] arm64: dts: ti: k3-am64-tqma64xxl-mbax4xxl: add SD-card and WLAN overlays As the SD-card and WLAN are connected to the same SDHC interface (with a GPIO-controlled mux), they are mutually exclusive. Provide Device Tree overlays for both configurations.
