Subject: [PATCH v3 5/9] arm64: dts: ti: k3-am62p: Add ITAP/OTAP values for MMC
Date: Tue, 13 Feb 2024 17:56:57 -0600 [thread overview]
Message-ID: <20240213235701.2438513-6-jm@ti.com> (raw)
In-Reply-To: <20240213235701.2438513-1-jm@ti.com>
Add OTAP/ITAP values to enable HS400 timing for MMC0 and
SDR104 timing for MMC1/MMC2. Remove no-1-8-v property to
enable the highest speed mode possible.
Update MMC OTAP/ITAP values according to the datasheet
[0], refer to Table 7-79 for MMC0 and Table 7-97 for MMC1/MMC2.
