Subject: [RFC PATCH 04/13] drivers: mmc: host: sdhci_am654: Add ITAPDLYSEL in sdhci_j721e_4bit_set_clock
Date: Tue, 30 Jan 2024 18:37:05 -0600 [thread overview]
Message-ID: <20240131003714.2779593-5-jm@ti.com> (raw)
In-Reply-To: <20240131003714.2779593-1-jm@ti.com>
Add ITAPDLYSEL to sdhci_j721e_4bit_set_clock function.
This allows to set the correct ITAPDLY for timings that
do not carry out tuning.
