From 8c121e6e3c7fd7be6e727ddd41880c202fb6e223 Mon Sep 17 00:00:00 2001 From: Judith Mendez Date: Tue, 14 Nov 2023 12:41:44 -0600 Subject: [PATCH] HACK: arm: dts: k3-am62p: add dll delay mapping for emmc Add in the input and output delay values for the available speed modes for the MMC controller for eMMC for the am62p5 allowing it to operate that the highest speed modes available. The patch is labeled as a HACK because the HS200 and HS400 values have not been finalized as of yet even though they have been tested.
