From ef00a95def6f6f5e2bd18ad3cb73834650768288 Mon Sep 17 00:00:00 2001 From: Francesco Dolcini Date: Mon, 25 Mar 2024 09:33:40 +0100 Subject: arm64: dts: ti: verdin-am62: use SD1 CD as GPIO MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit TI SDHCI instance has a hardware debounce timer of 1 second as described in commit 7ca0f166f5b2 ("mmc: sdhci_am654: Add workaround for card detect debounce timer"), because of this the boot time increases of up to 1 second. Workaround the issue the same way that is done on arch/arm64/boot/dts/ti/k3-am625-beagleplay.dts, using the SD1 CD as GPIO.
