From 9cbd5e8929c7e1a03d68afb582fc63792aa0238c Mon Sep 17 00:00:00 2001 From: Francesco Dolcini Date: Wed, 8 Mar 2023 12:36:22 +0100 Subject: arm64: dts: ti: k3-am625-verdin: fix SD1 driver strength Set SD1 interface driver strength to 33 Ohm (that is the minimum value we can configure), considering the additional 22 Ohm series resistor on the Development Carrier board we get to 55 Ohm that is the closest value to the ideal 50 Ohm we can get. Upstream-Status: Pending Initial DTS to be used for bring-up an validation of the V1.0 design, we'll decide on the step forward to mainline this once the bring-up and validation will be done.
